Surface water pollution treatment equipment

Abstract

The invention discloses surface water pollution treatment equipment which structurally comprises a base, a roller, a water inlet, a sludge outlet and a water outlet, sludge is contained in sewage andhas viscosity, a mucous membrane is easily formed between a screw rod and the inner wall of the roller, and a clearing block in a clamping block is moved out of the bottom of the clamping block through the thrust of the sewage; the fan blades in the clearing block rotate under the thrust of water flow, and the blades on the surfaces of the fan blades pierce mucous membranes of the screw rod and the inner wall of the roller so that impurities blocked by the mucous membranes are accelerated to pass through, the mucous membranes are reduced, the rotating speed of the screw rod is increased, and mud-water separation of sewage is accelerated; when the fan blades clears the mucous membranes, sludge and impurities in sewage are easily attached to the surfaces of the fan blades, the sewage is pressurized for multiple times through the impact plate, the impact force of the sewage is increased to impact the fan blades, falling of the sludge and the impurities on the surfaces of the fan blades isfacilitated, the gravity of the fan blades is reduced, the rotating speed of the fan blades is increased, and mucous membranes are accelerated to be pierced.

Description

technical field [0001] The invention belongs to the field of water pollution treatment, and more specifically relates to surface water pollution treatment equipment. Background technique [0002] Surface water is an important source of water for human life, and agricultural water is a part of surface water. Since a large amount of agricultural chemicals are used in agricultural water and mixed with sludge, in order to speed up the treatment and purification of agricultural water, the process of purifying agricultural water is first Use a sludge dehydrator to separate water and sludge; when using a sludge dewaterer in the prior art, because the sludge is sticky and mixed with agricultural water, when the screw inside the dehydrator rotates at a high speed, the screw will It is easy to form a water film with the inner wall of the drum, resulting in the impurity of small crops contained in the agricultural water being blocked by the water film, and the impurities are attached t...

[0002] Surface water is an important source of water for human life, and agricultural water is a part of surface water. Since a large amount of agricultural chemicals are used in agricultural water and mixed with sludge, in order to speed up the treatment and purification of agricultural water, the process of purifying agricultural water is first Use a sludge dehydrator to separate water and sludge; when using a sludge dewaterer in the prior art, because the sludge is sticky and mixed with agricultural water, when the screw inside the dehydrator rotates at a high speed, the screw will It is easy to form a water film with the inner wall of the drum, resulting in the impurity of small crops contained in the agricultural water being blocked by the water film, and the impurities are attached to the outside of the screw rod, which increases the bearing force of the outer blade of the screw rod, resulting in a slowdown of the screw rod speed. Sludge dewatering is slow
