摘要
水胺硫磷工业废水中 ,有机磷和硫化物含量均 >10 0 0 0mg/L ,COD高达 5 5 0 0 0mg/L左右 ,NH3 N在 4 0 0 0 0mg/L左右 ,BOD/COD仅为 0 .0 5 ,属典型难生物降解废水。本文采用常压酸性水解和脱氨除磷工艺处理该废水 ,有机磷、硫化物、NH3 N和总磷等去除率均 >90 % ,COD去除率达到 5 0 %以上 ,废水可生化性提高 ;同时 ,可回收得到硫氢化钠、氨水等物质 。
Wastewater from commercial manufacture of isocarbophos contains large amounts of organic phosphate compounds (total phosphate, TP), organic sulfides, COD and NH 3 N. In this paper, the wastewater was pretreated by acidic hydrolysis and deamination. The effects of initial pH values, temperature, hydrolysis time etc., on the removal of pollutants, along with the plausible mechanism of acidic hydrolysis, were investigated. The removal of TP, OP, S 2- and NH 3 N exceeded 90%, and the removal of COD attained 54%.
