沌口污水处理厂水质水量调查和预测.pdf

武汉理工大学硕士学位论文摘要目前我国水资源的短缺和水污染的加重,使人们警觉到水环境污染已直接关系到人民的健康安全和社会、经济的可持续发展。国内外的实践证明,污水处理厂是解决城镇水污染的有效途径。但由于许多原因,特别是资金的短缺使得城市污水处理厂的建设缓慢。同时我国拟建和已建的城市污水处理厂中,还存在很多问题。其中城市污水处理厂的设计水质、水量常与实际差别很大是最主要的一个。现已建成的许多南方城市污水处理厂多年来进水的水质和水量远小于设计值,未能充分发挥其效益。为了保证沌口污水处理厂将来的有效、经济运行,本课题对其进水水质、水量进行了调查和预测。通过调查本地区的水污染情况,评价出了开发区内的主要污染源和污染物。在一年水质和水量监测的基础上,分析了该区的水质、水量的现状和变化原因,其中特别考虑了泵站的运行和雨天对该区水质、水量的影响。考虑化粪池、地下水和完善度等方面,比较了调查结果和实测值间的差异。综合各项影响因素,对开发区2020年的水质和水量进行了预测。结果表明水量变化数倍,水质变化较小。这主要是人口的急剧增长导致的。在未来20年中生活污水的比重越来越大,而工业废水的比重越来越小,污水处理厂的进水将主要体现生活污水的特征。最后对开发区的水污染治理提出了一些建议。将污水泵站纳入污水处理厂的管理之中;普查雨污水管网,减少连通现象:选择适当的截流倍数截流初期雨水;将晨鸣纸业的部分工业废水纳入城市污水管道系统,提高沌口污水处理厂工业废水与生活污水的比重。关键词:沌口污水处理厂, 污染源评价, 水量预测, 水质预测武汉理工大学硕士学位论文 Abstract With theshortage ofwater and the seriousness ofwater pollution,it is aware tllatwater pollution has affected the people’s health security and Sustainable development insociety and indomestic and overseas prove thatWPT is an effective approach tosolve thewater pollution in urban and because ofmany difficulties,especially theshortage of fund,the、矿rPs develope ,there arcmany problems inthe ofthem is thewastewater quantity and quality inthedesign theconcentration and quantity of the inletwaste water which loadsthe、m inSouth China ismuch lower thanthelevel inthedesign stage. which causes thelowefficiency inWTP. Inorder tooperate economically and effectively,the wastewater quantity andquality ofZhuanKou、7汀P isinvestigated thebasisofthe investigation toWuHan Economic Development Zone’s water pollution,the main pollution resources andmatters are evaluated themonitoring of the waste water for one year,the present level ofwastewater quantity and quality and reasons are analysed,especially about pumping stations and rain. Considering septic tanks,ground water and petence degree,the conclusion differences between the investigation and the monitoring pared. Considering severalfactors,the wastewater quantity andqual
