Problems solved by technology

Taking the soil infiltration system as an example, the sewage is continuously degraded by microorganisms during the downward movement of the system. During this process, the phenomenon of poor sewage treatment often occurs due to insufficient carbon sources, resulting in poor treatment efficiency.

Embodiment Construction

[0029] see figure 1 . The sewage treatment device of the multi-stage water inflow vertical flow soil infiltration system of the present invention, its main structure includes:

[0030] The grid machine 1 performs grid treatment on the sewage to be treated, and separates and intercepts large solids in the effluent and suspended solids larger than the aperture of the grid to reduce the difficulty of sewage treatment. The sewage treated by the grid is introduced into multiple stages through the water inlet pipe 2 Water infiltration vertical flow soil infiltration system4.

[0031] The multi-stage water inflow vertical flow soil infiltration system 4 is provided with a top cover 5 to form a closed anaerobic environment for the multi-stage water inflow vertical flow soil infiltration system 4 . Below the top cover 5 are the surface soil layer 6 , the filter layer 7 and the water guide layer 8 sequentially from top to bottom. The surface soil layer 6 is also the water inlet layer...

Abstract

The invention provides a sewage treatment device of a multistage inflow vertical flow soil infiltration system. The device mainly comprises a grillage machine, the multistage inflow vertical flow soil infiltration system, an intermediate adjusting tank, a turbine screening tank and a discharge tank. The invention also discloses a method for treating sewage by utilizing the device. The device and the method have the positive effects that the device is small in floor area and is convenient to operate; the effluent treated by the device has high transparency and good quality; the device not only can kill aerobes such as pathogenic bacteria and eggs but also is short in reaction period and low in investment and takes effect quickly; the deep carbon sources of the soil infiltration system are ensured to be sufficient by utilizing multistage inflow and the remaining organic matters and other pollutants are intercepted by utilizing the turbine screening tank, so that the sewage is deeply purified and the effluent far exceeds the natural first-grade indicators.

Description

technical field [0001] The invention relates to a sewage treatment device of a multi-stage water inflow vertical flow soil infiltration system, in particular to a device for removing pollutants (such as organic matter, inorganic matter, microorganisms, heavy metals, etc.) in sewage. [0002] The present invention also relates to a method for sewage treatment using the above-mentioned device. Background technique [0003] Biological treatment of sewage is now very popular, and the process is becoming more and more mature, but many related problems are still unresolved and need to be further studied. For example, insufficient carbon sources are often found in the process of biological treatment of sewage. Taking the soil infiltration system as an example, the sewage is continuously degraded by microorganisms during the downward movement of the system. During this process, the phenomenon of poor sewage treatment often occurs due to insufficient carbon sources, resulting in poor...
