Furthermore, the box still includes the water inlet, and the water inlet setting is in the box lateral wall upper portion that is close to throw charging box one side, and the position of intaking is in throwing the charging tube below, throws the flocculating agent that the charging box throwed and can be taken away and spread by the rivers that get into, makes whole sewage treatment link just can realize certain homogeneity of throwing in the step of throwing the material.

Furthermore, the lower part of the box body is in a conical shape with a large upper part and a small lower part, the tail end of the box body is connected with a drain pipe, and a drain valve is arranged on the drain pipe.

Compared with the prior art, the sieve plate of the discharging pipe of the flocculating agent feeding box of the utility model can make the flocculating agent slowly fall into water, can be better dispersed, and the feeding position is above the water inlet, so that the flocculating agent can be driven to uniformly diffuse by utilizing the flowing action of the water inlet flow; according to the stirring device, the stirring blades are arranged in a stepped manner, the stirring effect can act on the sewage at each position through the layering of the stirring blades, the contact area between the blades and the sewage is large, and the flocculation efficiency is high;

the utility model discloses an foretell improvement just can realize the effect of better dispersion flocculation agent, the stirring process can adopt slower stirring speed, make the flocculation thing can not be because of acutely stirring and scatter with confusion, can be better deposit to the bottom, the flocculation thing of being convenient for accumulates and discharges again in the blow off pipe, set up the baffle before the delivery port and cover the delivery port partly, the lower stirring speed of reunion, can prevent to reduce the flocculation thing and get into the delivery port under stirring and cause the jam, to the risk that the drainage caused the pollution.
