Efficient filtering and purifying treatment device for domestic sewage

Abstract

The invention discloses an efficient filtering and purifying treatment device for domestic sewage. The device structurally comprises a filtering cabin, a precipitating cabin and a purifying cabin, wherein a cleaning door is arranged at the lower part of the left side of the precipitating cabin, the bottom of the cleaning door is rotationally connected with the precipitating cabin by a rotating shaft, and a handle is arranged at the upper side of the surface of the cleaning door; a motor and an agent storage tank are arranged in the middle of the top surface of the precipitating cabin, the lower side of the motor is connected with a stirring rod by a coupler, a bearing is arranged at the connected part of the stirring rod and the precipitating cabin, a stirring blade is arranged at the lower side of the stirring rod and located in the precipitating cabin, the bottom of the agent storage tank is connected to the interior of the precipitating cabin by a pipeline, a solenoid valve is arranged at the lower end of the pipeline, and a flocculant is stored in the agent storage tank. Sewage in the precipitating cabin can be stirred due to the arrangement of the stirring blade, so as to accelerate flocculation of the sewage, and reduce the precipitation time; and the interior of the precipitation cabin can be conveniently cleaned by the cleaning door.

Description

technical field [0001] The invention is a high-efficiency filtration and purification treatment device for domestic sewage, which belongs to the technical field of sewage treatment equipment. Background technique [0002] The amount of domestic sewage discharged by each person in the city is 150-400L per day, which is closely related to the living standard. Domestic sewage contains a large amount of organic matter, such as cellulose, starch, sugar and fatty protein; it also often contains pathogenic bacteria, viruses and parasite eggs; inorganic salts such as chloride, sulfate, phosphate, bicarbonate and sodium, Potassium, calcium, magnesium, etc. The general feature is high nitrogen, sulfur and phosphorus content, and under the action of anaerobic bacteria, it is easy to generate odorous substances. [0003] The existing domestic sewage treatment device takes a lot of time to settle the domestic sewage. The sedimentation equipment is large in size and occupies a large are...
