Sewage recycling and regenerating combined equipment

Abstract

The invention discloses sewage recycling and regenerating combined equipment which comprises a biochemical reactor, a cylindrical base, a platy base, a crypt machine room, an outer crypt machine room, an annular tank wall, a biological sand filter box, a semicircular partition, a biological activated carbon expanded bed, a water collection tank, SBRs, BAFs and a sludge concentration tank. Biochemical reaction, biological sand filtration and biological activated carbon biochemical degrading processes can be integrated in a combined pressure bearing tower, the combined pressure bearing tower can be assembled with the water collection tank, a jet-driven sequence batch biochemical reactor, a jet oxygenation biological contact filter and the sludge concentration tank to form the combined equipment, and the crypt machine room is arranged below the biochemical reactor, a biological sand filtration box and the biological activated carbon expanded bed. Flow pipelines and pipe fittings are reduced substantially, flow resistance is lowered, biochemical reaction efficiency is improved, land occupation area is compressed, construction cost is lowered, recycling and harmless sewage treatment is realized, recycling of water resources is promoted, and the water resources are saved.

Description

technical field [0001] The invention relates to a sewage resource regeneration treatment equipment, in particular to a sewage resource recovery regeneration treatment combined equipment. Background technique [0002] Commonly used sewage treatment facilities usually treat sewage until it reaches the legal discharge standard and discharge it into the environmental water body. Although this conventional treatment method can control the hazards of water pollution, it has little effect on saving water and alleviating the shortage of water resources. Although there are also reclaimed water reuse projects that are popularized and applied, they are only used for industrial cooling water, washing water, and irrigation water. Because its purification degree has not yet reached the original cleanliness before use, and there are also the shortcomings of conventional water purification facilities that occupy a large area, consume a lot of power, and are costly.

AI Technical Summary

Problems solved by technology

However, this technical solution has the following disadvantages: First, the baffle barrel installed inside the sewage biochemical treatment tower has a huge fluid energy dissipation effect, which weakens the function of entrainment and stirring of the water body, slows down the dynamic circulation of the water body, and is not conducive to the improvement of the mass transfer rate of the biochemical process.

Second, there is still room for exploration in the degree of structural integration

Third, there is still room for reducing the fluid resistance formed by pipes and fittings

Fourth, there is still a lot of room for improvement in the efficiency of jet-driven sequencing batch biochemical reactors and biofilter aeration and oxygenation equipment. The application was filed in November 2014 with the application number: 201410675125.4, which better solves the previous practical problem. The disadvantages of the new type improve the integration of the structure, reduce the system resistance again, and improve the processing efficiency, but the invention still has the following disadvantages: the distribution distance of the containers in the first few pretreatment processes is large, and the occupied land area is still relatively large There is still room for reduction in system resistance due to long connecting pipes and many pipe fittings and valves; the vertical arrangement of the main equipment results in an excessively large gravity difference between the upper and lower water bodies, resulting in increased energy consumption and steel consumption; and the above two This invention is not suitable for use in cold and freezing areas. Pipelines, pipe fittings, and valves are prone to freezing, and the cost of antifreeze and heat preservation increases; it consumes a lot of reinforced concrete materials, and it is difficult to transport large pieces to the construction site; there are also high construction costs and long construction periods for civil engineering Shortcomings
