Sewage recycling harmless treatment integrated equipment

Abstract

The invention relates to sewage recycling harmless treatment integrated equipment. A sewage biochemical treatment tower, a biological sand filter box and a biological activated carbon expanded bed are packaged into one pressure-bearing container and are separated into three sewage biochemical treatment units which can independently operate by virtue of conical and cylindrical separating plates, the three sewage biochemical treatment units are connected with a jet flow driving sequencing batch type biochemical reactor by virtue of a pipeline and a submersible sewage pump, the jet flow driving sequencing batch type biochemical reactor is connected with a biological contact filter chamber by virtue of a water decanter, the biological contact filter chamber is connected with the sewage biochemical treatment tower by virtue of a water pump and a jet flow gas mixing device, the sewage biochemical treatment tower is connected with the biological sand filter box by virtue of a water outlet valve of the sewage biochemical treatment tower, and the biological sand filter box is connected with the biological activated carbon expanded bed by virtue of a sand filter box water collecting pipe, a sand filter box water discharging pipe and a sand filter box water outlet valve. The sewage recycling harmless treatment integrated equipment has the advantages that sewage treatment recycling and harmless sewage treatment can be implemented, recycling of water source is realized, pollution of sewage to the environment is eliminated, and the water source is saved.

Description

technical field [0001] The invention relates to a harmless treatment device for recycling sewage, in particular to an integrated device for harmless treatment for recycling sewage. 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
