June 4, "World Environment Day" the day before, CCTV news broadcast a "save Ulansuhai Nur" News survey, seems to redefine the Ulansuhai Nur ecological deterioration of the main reason-agricultural pollution. Agricultural pollution too strong The survey found that in the Ulansuhai Nur inlet Fong Gu (sound) Yanghui, a large number of yellowish water is flowing from the canal to pump Ulansuhai Nur. Most of this water comes from local farmland, which accounts for 90% of the water Ulansuhai Nur. Screen shows that, because the upper reaches of the Ulansuhai Nur Bayan nur area is at the end of spring plowing, due to the high salinity of the local land, a large number of farmland and fruit in the cultivation of the Yellow River before the need to refer to a large area of water, the water through the Yellow River to remove most of the salt This led to the large amount of farmland water discharged into the Ulansuhai Nur. As a main reason for the ecological deterioration of the lake. The main reason, it seems, is understandable. As we all know, agricultural pollution is mainly from the use of chemical fertilizers and pesticides, because the current use of agricultural fertilizers in China is generally low, some fertilizer nitrogen and phosphorus components will flow into the rivers and lakes. But the problem is that only after the fertilizer has just been done, the sudden heavy rain flushing can take away a lot of fertilizer in the land. But it is not difficult to see from the screen, at present, most of the farmland discharged into the Ulansuhai Nur, is the local water pressure alkali after the retreat. Before watering the farmland did not carry on the use of fertilizer, at the same time, these farmland is in the autumn harvest after last year, has been barren, there is no fertilization after the possibility of pouring water pressure, at most the last year in the field of residual fertilizer residue. But after a winter of melting snow, it is estimated that most of it has penetrated deep into the soil. It can be seen that this period of farmland to take away the water should be saline-alkali components, rather than nitrogen and phosphorus composition of the majority of organic matter. So, the hasty conclusion is that the chemical fertilizer composition in the farmland retreat is the main reason for the Ulansuhai Nur ecological deterioration, and it is very arbitrary and lacks agricultural common sense. From the experience of my childhood in the southern countryside, I have seen parents in the paddy fields in the fertilizer soon, unforeseen heavy rain took away the rice paddy fertilizer ingredients, often complaining about weather, had to wait until after the sunny again to buy fertilizer. In the same way, it belongs to the Bayan Nur area with little rain in the northwest, suitable for crops such as maize (2427,-3.00,-0.12%) and sunflower. There are few like the southern paddy fields that water fertilization, basically is the field is poured through the water after the majority of fertilization, fertilizer along the moist soil infiltration to the root of the crop. In addition to part of the plant before the fertilizer, but these fertilizer is also watered the alkali, when sowing the use. The local farmers even basic common sense do not understand, in the water pressure alkali while still fertilizing? No, the farmers can't afford to buy the fertilizer. Obviously, the farmland water withdrawal is only a part of the Ulansuhai Nur ecological deterioration, if it is the main reason is too much move strong. In fact, the return of farmland is just a Bayan of the environmental officials of Nur. Making excuses for the federal pharmacy. As early as the end of March this year, the Reporter field interview, the local Ministry of Environmental ProtectionThe door of a deputy director, more plausibly said, this is a long-term problem, for a long time, agricultural chemical fertilizer use too much through the farmland water to Ulansuhai Nur ecological deterioration. This reporter asked if there is a relevant investigation report to support his conclusion, he said that this statement is from the agricultural sector. For the jurisdiction of the cod (chemical oxygen demand) sewage discharge of large large-federal pharmaceutical is particularly care. He explained that the federal pharmaceutical effluent was discharged to the Bayan Nur wastewater Treatment Plant and that the cod discharged into the sewage plant was below 400mg/l and discharged to the main canal after the treatment of the sewage treatment plant. With the current federal pharmaceutical API World's first production capacity, the daily average of the high concentration of cod wastewater will reach 25000 tons, and according to the cost of sewage treatment per ton of 30~35 (including electricity, labor, depreciation, pharmacy, etc.), the average daily sewage treatment cost is at least 750,000 yuan, The cost of sewage treatment in one year is as high as $270 million. Last year, the federal pharmaceutical net profit was only 160 million Hong Kong dollars, from this point of view, the federal pharmaceutical to achieve the cost of the discharge of the pressure is enormous. But in the eyes of the environmental official, federal pharmaceutical Wastewater treatment is the best in the industry, and the biggest investment. "The four or five-year federal environmental investment has reached 4% or 5% of total investment." "What surprised the environmental official, this reporter left the EPA to a sewage plant to find out, but catch up with the Bayan Nur sewage plant and the main canal connected to the drainage mouth" open door ", I do not know is the treatment of sewage or untreated sewage is a continuous flow of discharge, followed by the results of the water sample test showed that, Cod components up to 305mg/l, more than the sewage treatment plant after the discharge standard MG 5 times times more. In combination with the news survey, a local environmental monitoring staff in the two main trunk of the test results of water samples, cod values were 53.9mg/l and 61.3mg/l. Be aware that this is the cod value when returning water from a local farmland, but it is as high as 305mg/l at the end of March when no farmland was returned. The recent return of farmland has been a big help to local environmental officials-diluting the cod value of local industrial sewage. In fact, it is not authentic and unfair to Ulansuhai Nur the farmland as the main cause of the loss of water. Local farmers, who are already victims of industrial sewage, are now saddled with the "crime" of worsening Ulansuhai Nur's ecological environment. This is pure complement and lovely hetao farmer, too injustice! However, it is a good excuse for the local environmental authorities to try to divert the Ulansuhai Nur ecological deterioration to agricultural pollution. Can take away from their own environmental protection and supervision of the adverse line of sight, but also to its jurisdiction, such as the federal pharmaceutical, such as large polluters have done a cover. Although their wishful thinking played well, their acting level was too poor to be self-defeating. In the picture, the local central Supervision Detachment Horse Deputy Detachment Long led investigators, not industrial sewage source of the Linhe economic development zone, but the car dozens of kilometers, to no large industrialThe Wuyuan County of the park. A small, illiquid canal was found in the county, and it said they were looking around for no corporate sewage. The horse detachment pointed to the blackened canal water, explained that the drainage water is the irrigation infiltration water, because the crop orange rod rot causes the water quality to be blackened. From the picture shooting situation, the filming time should be in the late spring plowing in April or May, the picture of the official is too do not understand agriculture, spring sowing during the planting of how there will be a large number of agricultural water irrigation? At this time the most water is watered pressure alkali, through the large flow of the Yellow River to take away the salt and alkali composition of the ground, if the water seepage more then, first of all, this canal will not be so black, the second seepage increase will correspondingly improve the flow of water, but the screen black water is almost static. On the contrary, there will be plenty of farmland irrigation in July or August each year, when local crop production is booming, and the water should be the most permeable. In addition to the film said Ulansuhai Nur in the area of the annual water evaporation is very alarming, a wide about two or three meters of the soil canal can be the infiltration of the last year's irrigation waters retained for nearly 10 months, it is a miracle! Moreover, the canal is located in the Wuyuan County, less than dozens of kilometers away from the Ulansuhai Nur, so the flow is not strong channels, but also how the canal contains a large number of nitrogen and phosphorus components of agricultural irrigation infiltration of water into the Ulansuhai Nur? It is not hard to see, local environmental officials for the federal pharmaceutical, such as the sewage discharge of large cod to find excuses too strong, but self-defeating. In this, I suggest, instead of finding excuses, as in environmental monitoring more than a little effort to do more supervision. After all, the ecological deterioration of Ulansuhai Nur, leave you these environmental officials time is not much, has reached the point of no delay!
