摘要
为考察预水解对后续二级生化处理的影响,结合无锡市城北污水处理厂实际运行情况进行了生产性试验研究。结果表明,对于工业废水占40%的城市污水而言,原水经过水解预处理后的可生化性得到提高,并且由于水解池在未满负荷运行的情况下对碳源有机物的去除率较高,对后续硝化脱氨、反硝化脱氮和除磷存在不同的影响。
Plant experiments were conducted to investigate the effect of prehydrolysis on the secondary bio-treatmem in Wuxi Chengbei Wastewater Plant. It was believed that the bio-degradable character of influent was improved after the prehydrolysis of the urban sewage, of which industrial wastewater takes 40 %. The hydrolytic tank which was operating under the design load affected the followup processes, for insistence, the nitrification, the denitrification, and phosphor removal.
