Integrated three-dimensional circulation sewage treatment device

Abstract

The invention relates to the environmental protection technology, in particular to domestic sewage treatment equipment and aims at providing an integrated three-dimensional circulation sewage treatment device which is high in integration, stable and efficient. The sewage treatment device comprises a box, wherein the inside of the box is divided to form a circulating treatment area, a mud and water separation area and a filtration area in sequence; a partition plate is arranged in the middle of the circulating treatment area and divides an inner cavity of the box into an upper chamber and a lower chamber; the upper chamber is an aerobic chamber, and the lower chamber is an anaerobic chamber; an aerating device is arranged in the aerobic chamber, and a flow pusher is arranged in the anaerobic chamber; the two opposite ends of the partition plate are communicated with the aerobic chamber and the anaerobic chamber; the circulating treatment area is provided with a first water outlet leading into the mud and water separation area and the filtration area in sequence, and the filtration area is provided with a water discharge port. The integration of the device is improved remarkably, the equipment occupied area is greatly saved, the number of required power equipment is small, investment and energy consumption are reduced, and operation and management are convenient.

Description

technical field [0001] The invention relates to environmental protection technology, in particular to domestic sewage treatment equipment. Background technique [0002] Human domestic sewage 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, fat and protein; it also often contains pathogenic bacteria, viruses and parasite eggs; chloride, sulfate, phosphate, bicarbonate and sodium of inorganic salts , 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 development of existing domestic sewage treatment technology started relatively late, and the main process routes ar...

Problems solved by technology

However, the volume and integration of the equipment are still not good enough, and the sludge discharge is troublesome

Or the cylindrical processing device disclosed in CN101391834A, this device is a cylindrical shape with two layers inside and outside, and the integration is good, but the internal structure is too complicated, there are many partition ladders, poor running stability, and very troublesome to clean and maintain

CN201240939Y also discloses a cylindrical processing device, but the process route is simple, the device size is small, and there is no expansion capability, so the processing capacity is small and the practicability is poor
