Water recycling treatment device and method in four-section upward soil infiltration system

Abstract

The invention discloses a water recycling treatment device in a four-section upward soil infiltration system. The device mainly comprises a nano aeration ablation device, wherein a mud discharge opening is formed in the bottom of the nano aeration ablation device; a nano aeration disc is arranged above the mud discharge opening; effluent of the nano aeration ablation device is input into the lower part of the upward soil infiltration system; the four-section upward soil infiltration system is vertically divided into four packing areas; effluent of an overflow weir in the four-section upward soil infiltration system enters a surface turbulent flow screening device; the water outlet of a water storage tank of the surface turbulent flow screening device is connected with a photocatalytic degradation reaction device. The invention also discloses a method for treating sewage by utilizing the water recycling treatment device in the four-section upward soil infiltration system.

Description

technical field [0001] The invention relates to a water reuse treatment device in a four-stage ascending soil seepage system. [0002] The present invention also relates to a method for sewage treatment using the above-mentioned device. Background technique [0003] The soil infiltration system is widely used in domestic sewage in small and medium-sized towns and rural areas due to its relatively low construction and operating costs, convenient management, strong adaptability to load changes, certain biological safety of the effluent, and significant ecological and environmental benefits. deal with.

AI Technical Summary

Problems solved by technology

However, in the long-term operation of the soil seepage system, it is inevitable that there will be clogging, which is an important problem to be solved in the application.

For the composite vertical flow soil infiltration system, it is mainly due to the blockage of the upper layer of the down-flow tank, which causes the water accumulation layer on the surface of the down-flow tank, which prevents the oxygen in the air from entering the substrate layer, and reduces the activity of aerobic microorganisms in the composite vertical flow.
