[0002] The sewage source heat pump system uses the energy in the sewage as low-level energy. Through a small amount of electrical energy input and non-clogging sewage heat exchange and heat pump technology, it develops and utilizes the low-level thermal energy that is difficult to utilize in the sewage. In order to decontaminate the sewage source heat pump system, a corresponding decontaminator is required.

[0003] The reference publication number is CN210728828U, which is a rapid decontamination device for a sewage source heat pump system. The decontamination device comprises an outer shell with an inlet end and an outlet end, and an upper filter cylinder and a lower filter cylinder installed in the outer shell and arranged in parallel at the upper and lower ends. The outer shell is provided with a sewage outlet, and the front ends of the upper filter cylinder and the lower filter cylinder are connected to the inner wall of the inlet end. The decontamination device is used to block sewage from entering the filter cylinder through the front partition, thereby realizing the flushing of the partitioned filter cylinder, and the rear partition is used to isolate the connection between the filter cylinder and the sewage outlet, thereby realizing the filtering effect of the filter cylinder where the partition is located on the sewage.
