生活污水中公厕粪水处理的卫生指标检测研究
Study on Detecting the Hygienic Indexes in Processing Manure Water from Public Toilets of Domestic Sewage
摘要
Abstract
[Objective] The study aimed to analyze the detection bacteria of hygienic indexes in the process procedure of wastewater from public toilets. [Method] The samples were collected randomly from many sites in the septic banks of public toilets of Yunnan Normal University. The wastewater from public toilets was processed by hydrostatic anaerobic-natural aeration processing system with retention time of 32 d. The fecal coliform and total amount of bacteria in intaken and discharged water samples were measured. [Result] The fecal coliform in the wastewater from public toilets could be removed by 99.03% through three-grade continuous anaerobic process, it reached the hygienic standard GB7959-87 for removal rate in fecal innocence. The correlation between retention time of processing procedure of anaerobic digestion and total amount of bacteria was not obvious, indicating that the hydrostatic anaerobic fermentation process could kill fecal coliform better and reduce the total amount of bacteria. After the fecal coliform was processed by continuous anaerobic processing, the color of isolated colonies on plate became lighter, also indicating that the anaerobic fermentation reduced the harmfulness of harmful bacteria. [Conclusion] The processed wastewater from toilets could be used as irrigation water in urban greening so as to relieve the stress of water resources, but the supervision on processing procedure should be enhanced to avoid secondary pollution.关键词
