摘要
随着我国人口的增长,人民生活水平的日益提高及经济的迅猛发展,工业化、城镇化步伐加快,生活污水排放量也随之增加。生活污水中的有机物、病原菌、虫卵等直接排入水体或渗入地下将造成严重污染。据此,本文采用厌氧—厌氧—好氧—沉降工艺,设计出小型合并处理净化槽。经国标法——重铬酸钾测试方法测定,理论上系统中COD的去除率在90%左右,达到城市污水处理厂排放水质标准的二级标准。该净化槽具有体积小、结构紧凑、污水处理效率高等特点,适用于家庭自备或小城镇内污水处理。
With the growth of population in our country,because of the rising standard of people's living standards and the rapid development of China's economy,the pace of industrialization and urbanization has been accelerated,the domestic sewage discharge has also increased.Domestic sewage contains organic matter,pathogens,eggs,etc.,directly permeating into the water or the ground which will cause pollution.According to this situation,in this paper,an anaerobic-anaerobic-aerobic-sedimentation process is used to design a small-scale treatment purification tank.Depending on the determination of GB method-Test method for potassium dichromate,in theory,COD removal rate of the system is about 90%,which reaches the secondary standard of the urban sewage treatment plant discharge water quality.The purification tank has the characteristics of small volume,compact structure and high efficiency of sewage treatment,it can be used for home-owned or small areas of sewage treatment.
