Adjustable storage sewage treatment device and combined system

The utility model relates to an adjustable storage sewage treatment device and a combined system. The sewage treatment device comprises a coagulating sedimentation unit, an ammonia nitrogen ion exchange regeneration unit and an organic matter biological treatment unit. Compared with the prior art, quality and efficiency improvement of a sewage treatment plant can be effectively realized, and the problem of black and odorous water body caused by overflow of rain and sewage mixed water during rainfall is solved. The provided operation mode can effectively solve the problem that microorganisms in a sewage treatment system are difficult to maintain relatively high activity in a rainfall intermittent period, and also can well solve the problem that the treatment efficiency of the ammonia nitrogen ion exchange column fluctuates along with seasons. 本实用新型涉及一种可调蓄污水处理装置、组合系统，该污水处理装置包括混凝沉淀单元、氨氮离子交换再生单元和有机物生物处理单元。与现有技术相比，可有效实现污水处理厂的提质增效，并解决降雨时雨污混合水溢流而造成的水体黑臭问题。所提出的运行模式可以有效解决污水处理系统中的微生物在降雨间歇期内难以维持较高活性的难题，同时也可以很好地解决氨氮离子交换柱
