浅谈生活污水处理技术

浅谈生活污水处理技术浅谈生活污水处理技术摘要:在城市污水管网尚未铺就或不可能到达，或尚未建成城市污水处理厂的城市的住宅小区，生活污水处理一直都是很难解决的问题。过去常用的化粪池沉淀和厌氧发酵，虽然对悬浮物质和寄生虫卵有一定的去除作用，但BOD5去除率很低，且不具备脱氮除磷功能，已不能满足水污染防治和水环境保护的需要。近年来，适用于住宅小区的小型污水处理站和污水处理设备的技术开发发展迅速。本文拟就这方面的成果进行论述，并对存在的问题提出看法。关键词:生活污水处理；技术开发；问题探讨【Abstract】Haven'tspreadatthecitysoilpipenetorimpossiblearrive,orhaven'tbuiltupcitywastewatertreatmenttheresidencesmallareaofcityofthefactory,lifethewastewatertreatmenthavebeentheproblemthatcanhardlysolve.Pasttheincommonuseseptictankprecipitatewithbedisgustedwithoxygentoferment,althoughcleanafunctiontowardssuspendingmaterialandparasiteeggtohavecertainlyof,theBOD5cleanarateverylow,anddon'thavenitrogenoftakeoffinadditiontoLinfunction,alreadycan'tsatisfywaterpollutionpreventionandcureandwaterenvironmentalprotectionofdemand.Inrecentyearsbeapplicabletothesmallscaledwastewatertreatmentstationoftheresidencesmallareaandthetechniqueofthewastewatertreatmentequipmentsdevelopmentdevelopmentquick.Thistexthasdraftedtheresultofthisaspecttocarryondiscuss,andtoexist
