2. The part of solid treatment agents are easy to suspend on the surface of sewage due to the buoyancy and surface tension of the sewage after being added into the sewage treatment device, so that the contact area of the agents and the sewage is small, the mixing reaction effect with the sewage is poor, and the full play is difficult.
3. The part of sewage treatment device adopts the inlet pipe to introduce the treatment agent into sewage, so that part of undissolved treatment agent is accumulated or adhered on the pipe wall, and the inlet pipe is easy to be blocked.
4. The existing sewage treatment device is generally difficult to accurately control the adding amount of treatment agents, excessive treatment agents are added into the sewage treatment device to ensure the complete progress of the reaction, and the parts which are not dissolved or do not participate in the reaction in the treatment agents are discharged along with sewage after the sewage treatment is finished, so that the waste of resources is caused, and secondary pollution is extremely easy to cause.
