After the blocking sleeve (21) is unscrewed from the end of the material conveying pipe (20), the liquid sewage treatment agent conveying pipe is sleeved on the material conveying pipe (20), the liquid sewage treatment agent is supplemented into the storage rack (2), the switch of the pump body (22) is triggered, the pump body (22) injects the liquid sewage treatment agent in the storage rack (2) into the enclosing rack (5), and the liquid sewage treatment agent is scattered through the plurality of through holes (7) and flows into the sewage tank together with the sewage.

5. The method according to claim 4, wherein the water treatment agent is added to the printing and dyeing wastewater in the form of a tablet. After the head (16) is unscrewed from the feeding port (14), the fine particle sewage treatment agent is put into the feeding ball (8), the head (16) is screwed and sealed in the feeding port (14), after one end of the rope body (28) is bolted to the pull rod (15), the feeding ball (8) is put into the sewage pool, the counterweight (9) increases the weight of the feeding ball (8), the feeding ball (8) gradually sinks to the bottom of the sewage pool, the fine particle sewage treatment agent is mixed with the sewage through the perforation (10), after the switch of the servo motor (31) is triggered, the stirring shaft (12) is driven to rotate, the fine particle sewage treatment agent and the sewage are mixed by the stirring shaft (12), and the mixed liquid diffuses outward through the perforation (10).

6. The method according to claim 5, wherein the water treatment agent is a dyeing wastewater treatment agent. When the feeding ball (8) needs to be salvaged, the hand screw rod (26) is unscrewed from the positioning groove (27), at this time, the rotating disc (23) lacks braking, the rotating disc (23) is rotated by pinching and pulling the ring (24), the rotating disc (23) winds the rope body (28), the rope body (28) pulls up the feeding ball (8), after the feeding ball (8) is salvaged, the hand screw rod (26) is screwed and inserted into the positioning groove (27), and the rotating disc (23) is braked.
