A high hydraulic load garden land infiltration system and treatment method for rural sewage treatment

Abstract

The invention discloses a garden land percolation system with high hydraulic loading for treating rural sewage. Water distributors are uniformly distributed at both sides of crops, a plurality of drip holes are distributed along the length direction of the water distributors at equal intervals; drainage pipes are distributed in the middle two rows of crops, a plurality of drainage holes for collecting treated sewage are distributed along the length direction of the drainage pipes, and each drainage pipe is wrapped with a water permeable geomembrane; the water distributors are in parallel with the discharge pipes; treated wastewater is collected to the water collector wells by water collector pipes perpendicular to the drainage pipes. The invention also discloses a treatment method of rural sewage. According to the garden land percolation system and the treatment method disclosed by the invention, due to direct holing on a water dropper instead of carrying out drop irrigation by virtue of a drip irrigation emitter, sewage can directly drop from dripholes to soil, and thus the occurrence of clogging of the emitter can be effectively avoided; because of the introduction of an underground drainage system, the sewage treatment capacity of the system is effectively improved and purified water is conducive to be collected; the rich resources of garden land in China are taken as a carrier for treating sewage, the soil is not subjected to modification, and thus construction is simple, management is easy and sustainability is good.

Description

technical field [0001] The invention relates to the technical field of sewage ecological treatment, in particular to a high hydraulic load garden land infiltration system and treatment method for rural sewage treatment. Background technique [0002] With the rapid economic development in rural areas of our country, environmental problems are becoming more and more serious. At present, rural sewage has caused great harm to the living environment and the health of residents in rural areas, and has seriously threatened the national water environment security. Rural areas have low population density and scattered residences. Building sewage treatment plants not only costs a lot, but also wastes a lot of clean water in the process of transporting sewage. Therefore, low-cost, high-efficiency, and environment-friendly sewage ecological treatment technology has been paid more and more attention by researchers. [0003] Land treatment systems control the application of sewage to th...
