摘要/Abstract

摘要： 本文研究了模拟稳定塘系统去除污染指示菌如总大肠菌群(TC),粪大肠菌群(FC),粪链球菌(FS)以及异养细菌(HPC)的作用。结果表明,16℃时污水在日进污水10t的模拟稳定塘系统停留9天后,TC与FC的密度下降4个数量级。在日进污水90t,污水理论水力停留时间10天的模拟稳定塘系统进行的全年跟踪监测结果表明,TC与FC密度随各塘依次递减。Ⅳ号塘出水的TC密度下降2.5个数量级,基本上达到了我国GB3838-88中规定的地面水Ⅲ级标准;FC密度下降3个数量级,达到WHO标准的轻污染水平,肯定了稳定塘系统去除污染指示菌的有效性。

Abstract: In this paper, the removal efficiencies of total coliforms(TC), fecal coliforms(FC), fecal streptococcus(FS) and heterotrophic plate count(HPC) in simulated stabilization pond systems were studied. In the system treating10 t of wastewater per day, the densities of TCand FCdecreased by 4 orders of magnitude in9 days at 16℃. Bacterial enumeration in the system treating90 t of wastewater per day was conducted yearly. The densities of TCand FCin its effluent decreased by 2.5 and 3 orders of magnitude respectively. The effluent quality of the system, in terms of TC, reached approximately to Ⅲ degree of surface water quality standard. According to WHO's standard, the effluent quality, in terms of FC, was of "slight pollution". The results indicated that the two systems can effectively remove TCand FC.
