摘要:
针对某工业园中2家工厂产生的高浓度印染废水,分析了原处理工艺存在的问题,在充分利用现有设施的前提下,提出了利用部分构筑物,对2家工厂产生的高浓度废水采用水解酸化—混凝—接触氧化的改进工艺。改造后的运行结果表明,废水处理系统对COD、BOD5、SS、色度的去除率分别达到95.3%、92.4%、93.9%、98.4%,出水各项指标均优于《广东省水污染物排放限值》(DB 44/26—2001)第二时段中的一级标准,并实现了部分回用。

Abstract:
Aiming at the printing and dyeing wastewater with high concentration discharged from two factories in an industrial park,the problems existed in their original treatment processes have been analyzed. On the premise of making full use of present facilities,it is suggested to use part of the constructions. The high-concentration wastewater in those two factories has been treated by the modified process of hydrolytic acidification -coagulation-contact oxidation. The running results obtained after the modification show that the removing rates of COD,BOD5,SS,and chroma are 95.3%,92.4%,93.9%,and 98.4%,respectively. Every index of the effluent is superior to the first grade of the second period of guangdong province local standard:Guangdong Province Discharge Limit Value of Water Pollutants(DB 44/26—2001). Part of the effluent can be reused.
