The utility model discloses a multi-stage treatment device for domestic sewage, including a filter pool, an aeration pool, a sedimentation tank and a clear pool. A filter net is provided on one side of the filter pool, an aeration pool is provided on one side of the filter pool, a filter pool and a aeration pool are separated by a partition I, and a number of outlet is provided on the partition board I, and one side of the aeration pool is set. There are aeration pipes with a number of aeration branches on one side of the aeration pipe, a number of evenly distributed aeration heads on the aeration branch pipe, and a sedimentation tank on one side of the aeration pool, the vertical height of the separator II is lower than the vertical height of the partition I, the bottom side of the partition plate is equipped with a back mud tube, and the bottom of the sedimentation tank is higher than the bottom of the aeration pool; precipitation is higher than the bottom of the aeration pool. There is a clear pool on one side of the pool. The utility model first filters the large particle impurities in the sewage, reduces the pressure of the subsequent sewage treatment, and uses the height difference of the treatment pool partition board to automatically flow the sewage, reduces the input of the equipment, and reduces the energy consumption of the sewage treatment device.

一种生活污水多级处理装置
本技术属于环保设备
,特别涉及一种生活污水多级处理装置。
技术介绍
随着城市人口的日益膨胀和工农业的不断发展,水资源污染越来越严重,尤其是城市水质较为严重;污水未经处理就排放,不仅会对生态环境造成严重的污染,更会造成水资源的浪费。经过检索,申请号为201620950716.2的技术专利公开了一种污水处理系统,该污水处理系统曝气池底部设置有若干曝气头;沉淀池与曝气池之间设置有曝气水输送管道;气浮池与沉淀池之间设置有沉淀水输送管道;过滤池内部设置有过滤层,过滤池与气浮池之间放置有移动水泵;清水池与气浮池之间设置有清水管道一,与过滤池之间设置有清水管道二,清水管道一与清水管道二上均设置有水泵,其在污水处理时先进行曝气再沉淀和过滤,污水中的大颗粒杂质伴随污水处理的整个过程,最后才被处理,增加了污水处理系统的压力,且其在相邻的污水处理池上均设置了水泵,不仅增加了设备的投入,而且增加了污水处理系统的能耗。
技术实现思路
本技术的目的是克服现有技术中不足,提供一种生活污水多级处理装置,先对污水中的大颗粒杂质进行过滤,降低了后续污水处理的压力,且利用处 ...
