******〔东区〕生活污水处理及中水回用工程方案设计
摘 要
******每天都产生大量生活污水，在水资源日益匮乏的今天，如果这些废水能被很好的利用起来，将能很好的缓解本学院的用水压力，所以我们方案将学校污水处理后再利用。所谓回收再利用就是将水处理到中水水质的程度，再利用其浇灌花木、冲洗厕所、洗车等。针对这一想法我们设计了污水处理再利用的方案，设计过程分为三局部：普通污水处理、消毒深度处理、中水回用。其中普通污水处理我们采用CASS池法，同时到达脱氮除磷的目的，深度处理局部采用机械搅拌澄清池进行初步沉淀，之后经过滤池过滤最后经过消毒池以到达中水回用的目的。设计时因学校水量不稳定，故采用初沉调节池进行水量调节，本设计工艺仅采用一台污水提升泵，置于初沉调节池内，将水提升至CASS池内进行生物处理继而进行深度处理。

Luoyang Institute of Technology (East) sewage treatment and water reuse project design
ABSTRACT
Luoyang Institute of Technology have a large number of daily domestic sewage, the increasing scarcity of water resources today, if they can be a very good use of waste water, and will be able to alleviate the College of good water pressure, so we plan to school sewage to deal with later use. The so-called recycling is in water treatment to the extent of water quality, water re-use of its flowers and trees, flushing toilets, car washing and so on. In response to this idea, we designed the sewage treatment program reuse, design process is divided into three parts: the general waste water treatment, disinfection of the depth of processing, in water reuse. Which we have adopted a common sewage treatment pond CASS law, at the same time to achieve the purpose of nitrogen and phosphorus removal, the depth to deal with the use of mechanical agitation to clarify some of the preliminary sedimentation tank, through filter after filter after the final disinfection of pool water in order to achieve the purpose of reuse. Design of water due to instability in schools, the regulation of the use of primary sedimentation tank for water regulation, the design process is only used to upgrade a sewage pump, placed in primary sedimentation tanks conditioning will be upgraded to CASS water tanks for biological treatment and then the depth of processing .
