Abstract
The microbiological quality of effluents from different macrofiltration systems (pressure sand filter and disc filter)used as pre-treatment and membrane technologies (microfiltration and ultrafiltration) was evaluated in order to determine their possible application as alternatives to disinfection of urban wastewater prior to reutilization. Microbiologicalquality was determined by reference to nematode egg content, fecal coliforms, E.coli and somaticcoliphages. Pathogenic nematode eggs were efficiently retained by the macrofiltration systems. However, since othertypes of nematode eggs were present in the effluents treated by both systems, the possibility of such infective agentsappearing after this type of treatment cannot be discounted. The membrane technologies proved highly efficient atretaining micro-organisms, achieving effluents of excellent microbiological quality. However, the effluents could notbe classified as sterile, since contamination of permeation zones gav

摘要
微生物质量的污水，由不同macrofiltration系统（压力砂滤器和盘式真空过滤机） ，作为前处理和膜技术（微滤和超滤）进行了评价，以确定其可能的应用作为替代消毒城市污水之前再利用。 microbiologicalquality确定参照线虫的鸡蛋含量，粪大肠菌群，大肠杆菌和somaticcoliphages 。病原线虫虫卵有效地保留了由macrofiltration系统。不过，由于othertypes线虫虫卵，目前在污水处理两个系统的可能性，这种感染agentsappearing后，这种类型的治疗，不能打折扣。膜技术证明，高效atretaining微有机体，实现了废水的优良微生物质量。然而，废水可以notbe列为无菌的，因为污染的渗透区，引起了在场的微生物。 thisresult令人怀疑的有效性，用粪大肠菌群指标，以评估微生物学质量的污水fromthese系统。两国间的分歧膜分离技术则对于病毒粒子retentioncapacity ，只有超滤模块，实现废水完全没有粪便污染indicators.the macrofiltration系统可能存在的问题时，用来作为前处理，以标准的消毒系统（ uvradiation ，无功氧化剂消毒） 。这些问题，不出现与膜分离技术，它提供avalid替代消毒城市污水之前再利用
