The production of glyphosate-resistant wastewater from the substandard drug industry

Business June 18 News environmental Verification Notice issued just half a month, there are enterprises hit the muzzle. June 10, CCTV exposure Hengyang Bio-Pharmaceutical Co., Ltd. Jinyan Branch open to the Xiangjiang River discharge of sewage, the local environmental Protection Department said it has stopped production. Hengyang Levin Bio-Pharmaceutical Co., Ltd. is a former Hunan Tianyu Pesticide Chemical Group Co., Ltd. restructuring of a joint venture, is a national fixed-point pesticide production base, Hunan's largest set of science, industry, trade, technical services in one, with self-import and export rights of pesticide production enterprises. Jinyan Chemical plant to produce 95% grass glyphosate drugs, annual output of up to 12000 tons. CCTV exposed sewage should be produced by the production of glyphosate waste water. According to industry insiders, Hengyang Levin Biological Pharmaceutical Co., Ltd. production of glyphosate is the use of glycine process, the process of production of 1 tons of glyphosate will produce crystalline mother liquor 5-6 tons, plus other production links, each production of 1 tons of glyphosate produced waste water estimated at about 20 tons. Lednen produces 12000 tons of glyphosate, the amount of wastewater discharged can reach almost 240,000 tons, pollution is conceivable. Glyphosate wastewater is an organic high concentration heavy metal waste water discharged from the process of producing glyphosate powder and agent in pesticide industry. The main raw materials for the production of glyphosate are two ethanolamine, flake alkali, deionized water, hydrochloric acid, formaldehyde, phosphorus trichloride, 30% liquid alkali, heavy metal catalysts, hydrogen peroxide, sodium tungstate, liquid ammonia, ferrous sulfate and so on. Environmental verification clearly points out whether there will be a mother liquor recovery treatment device as one of the verification content, according to CCTV unannounced investigation of the results of water samples, COD (chemical oxygen demand) 1590mg/l,ph11.54, total phosphorus 453mg/l. According to the gb8978-1996 sewage comprehensive discharge standard, in the sewage discharge unit discharges the second class pollutant, the organic phosphorus pesticide industry highest allowable emission concentration level standard is 100mg/l, the element phosphorus is 0.1mg/l,ph is 6-9. It can be seen that the water sample test results far exceed the sewage discharge standard. Some insiders pointed out that Ryder did not carry out sewage treatment, belong to the straight row, to the current grass glyphosate medicine 37000 yuan/ton quotation to calculate, its production of 1 tons of glyphosate almost can benefit 10,000 yuan.
