摘要随着我国经济建设的发展,工业现代化速度的加快,人口高度集中,在选择处理污水处理工艺时,应考虑校园生活污水处理的特点:学校虽为用水大户,但校园生活污水污染程度低,污染物成分比较单一、重金属含量少、用水时间相对集中。根据本设计要求处理量为1000m3/d的校园生活污水,由于进水水质BOD/COD=0.6,BOD/COD较大,污水的可生化性较高,因此本设计采用生化处理的方法。设计时即要求达到排放标准,又要使处理费用、基建费用等综合费用达到最小,还要是处理环境美观。结合处理水质、污水排放标准、处理成本、处理环境等因素,本设计采用生物接触氧化处理工艺。生物接触氧化法兼有活性污泥法的特点,容积负荷高,处理时间短,不存在污泥膨胀问题,污泥产量低,对水质的适应能力强。关键词:生活污水,可生化性,生物接触氧化法AbstractAs Chinas economic development, industrial modernization and the accelerating pace of the population is concentrated, in the handling of the sewage treatment process, it should consider sewage treatment campus life features : water for the schools, despite the big But campus life low level of sewage pollution, pollutants Components of a single, heavy-metal content of less, the relative concentration of water time.According to the design requirements for the handling capacity of 1,000 m3 / d of campus life sewage, As the influent water BOD / COD = 0.6, BOD / COD larger sewage biodegradability higher Therefore the design using biological treatment methods. Design requirements that meet emission standards, so that the processing costs, the costs of infrastructure, such as minimizing the overall cost, It has to be dealt with landscaping. The combination of water quality, sewage discharge standards, the cost of processing, handling and other factors. The design of the use of biological contact oxidation process. Biological contact oxidation of both activated sludge characteristics, high-volume load, short processing time, There is no question of sludge bulking sludge low output and quality of the adaptation capability. Keywords : sewage, biochemistry, biological contact oxidation
