摘要
对不同工艺废水采用物化方法分质预处理后,利用厌氧-缺氧-CAST组合工艺处理综合废水,设计处理量为470 m3/d.运行实践表明:中和反应-混凝沉淀对总磷的去除率可以达到46％,整个工艺处理出水COD稳定低于500 mg/L,总磷稳定低于8 mg/L,出水水质达到接管要求.
Abstract
Different kinds of industrial wastewaters have been pretreated by physicochemical processes,and AA-CAST Process was used to treat comprehensive wastewater.The designed treatment capacity is 470 m3/d.The operation results show that the removing rate of COD and total phosphorus reach 68％and 46％respectively after treated by neutralization and coagulation sedimentation.Treated by the whole process,the effluent COD is less than 500 mg/L,total phosphorus is less than 8 mg/L.The effluent water quality can meet the take-over requirements.
