| 摘 要： | 通过混凝+两段活性污泥法对硝化棉废水处理工程运行效果的分析,研究了在不同的温度条件下利用不同的运行方式所产生的运行效果,寻求系统的优化运行方法。结果表明:当水温在18℃以上时,只采用两段生化(低氧-好氧)处理即可使出水CODCr、BOD5、SS等指标达到国家《污水综合排放标准》(8978—1996)二级标准,仅出水色度稍高;而当水温T<18℃时,经过两段生化处理后废水CODCr在300mg/L以上,需要启动物化处理单元,在生化处理前或后增加一级混凝沉淀处理,处理出水均可达到二级标准要求。

| Abstract: | In this paper,the operation effect at different temperature and conditions was studied by using the "coagulation and two phase activated sludge" combined treatment process in nitrocellulose wastewater treatment works. The running result shows that the outlet water CODCr,BOD5 and SS etc. achieve the second grade standard of GB8978--1996《General sewage discharging standards》by just using two-phase biochemical process(low oxygen and aerobic process),expect for the chroma when the water temperature was 18 degre... |
