A domestic sewage filter device

Abstract

The invention discloses a domestic sewage material filtering device, and belongs to the technical field of domestic sewage treatment. The domestic sewage material filtering device comprises two relatively large box bodies (a solid impurity filtering box and an organic matter cleaning box), a connecting pipe and an oil liquid filtering box, wherein the connecting pipe is used for connecting the solid impurity filtering box and the organic matter cleaning box; the oil liquid filtering box is arranged on the connecting pipe; the solid impurity filtering box is separated into a large solid filtering region and a small solid filtering region by a separation plate; a rotating blade group and a first rotating cylinder of a windmill structure are arranged in the large solid filtering region; fixedcutter teeth and blade cutter teeth which are matched are arranged at one side of a first fixed cylinder body and rotating blades; first through holes are formed in the side wall of the first rotating cylinder; the first rotating cylinder is filled with active carbon; a second rotating cylinder and rotating fan blades are arranged in a small solid filtering cavity; reticular metal filled with quartz sand and zeolite is arranged between the rotating fan blades; third through holes are formed in the side wall of the second rotating cylinder; the domestic sewage material filtering device is alsoprovided with a solid accommodating box and a water body accommodating box. The domestic sewage material filtering device has the advantages that the design is reasonable and is optimized; the structure is compact; the occupied space is relatively small; the work flow process is short; the treatment efficiency is high; the treatment effect is better.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a domestic sewage filter material device. Background technique [0002] Domestic sewage is mainly the discharge water produced by various kitchen water, washing water and toilet water used in human life, and most of them are non-toxic inorganic salts. Sewage produced in the process of human life is one of the main sources of water pollution. Mainly feces and washing sewage. 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 fat protein, etc.; it contains chloride, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, magnesium, etc. of inorganic salts. The general feature is high nitrogen, sulfur and phosphorus content, and under the action of anaerobic bacteria, it is ...
