Problems solved by technology

[0005] Rural areas lack a complete separation and collection system for rainwater and sewage. According to the urban sewage treatment model, a huge rainwater and sewage pipe network needs to be laid. The investment is high, the operation, management and maintenance of sewage treatment facilities are high, and it is difficult to operate stably for a long time. The current needs of rural domestic sewage treatment

Embodiment 1

[0038] An ecological system for comprehensively treating rural rainwater pollution in hilly areas of the present invention is composed of an improved three-compartment septic tank, an ecological pond, a water collection well, a waste flow device, a permeation well, a first valve and a second valve;

[0039] The improved three-compartment septic tank consists of the first pool (1), the second pool (2), the third pool (3), the wall (4), the feces inlet pipe (5), the exhaust port (6), and the Fecal pipe (7), clapboard (8), hexagonal honeycomb inclined pipe (9), feces discharge pipe (10), slag cleaning port (11) and septic tank cover plate (12); the first pool (1 ), the volume ratio of the second pool (2) and the third pool (3) is 2:1:3, and the pools are connected by the feces pipe (7); the feces inlet pipe (5) is arranged in the first pool (1 ) in the wall (4) on one side, the exhaust port (6) is at the top of the first pool (1) near the feces inlet pipe (5); the bottom section ...

Embodiment 2

[0044] In a rural area in a hilly area, ecological technology is used for comprehensive treatment of domestic sewage and rainwater runoff. The rural houses are built close to the mountains, and the distribution is relatively dense. The road has a steep slope. A river with a width of 1.5m flows through the village and flows into the water source. The main economic crop is rice.

[0045] There are 5 people per household in this village on average, and the volume of the improved three-compartment septic tank is calculated and designed to be 2.4 m 3 . The new improved three-compartment septic tank has high anti-seepage performance. The volume ratio of the first tank (1), the second tank (2) and the third tank (3) is 2:1:3. The pipe (7) is connected, the wall (4) is made of concrete bricks, plastered with anti-seepage materials, and the top is covered with a reinforced concrete septic tank cover (12). The tops of the first pool (1) and the third pool (3) The slag removal port (11...

Abstract

The invention discloses an ecological system for comprehensively treating rural rainwater and sewage in hilly areas. The ecological system is composed of an improved three-grid septic tank, an ecological pond, a water collecting well, a flow discarding device, an infiltration well, a first valve and a second valve. Rural rainwater and domestic sewage in the hilly areas are comprehensively treatedin an ecological treatment mode. The domestic sewage treatment system comprises the improved three-grid septic tank and the ecological pond, wherein the ecological pond consists of a drop-type ecological water distribution channel and a main body. A rainwater runoff treatment system comprises the water collecting well, the discarding device and the infiltration well, rainwater runoff is filtered,infiltrated and accumulated through the infiltration well to be used for supplying underground water, and an overflow part is used for guiding water to activate the ecological pond or used for agricultural irrigation and direct drainage of rivers together with effluent of the ecological pond. The ecological system is novel in structure, rainwater and sewage are collected in an unpowered self-flowing mode, rural rainwater and sewage comprehensive treatment and water resource utilization are achieved, and the system has the advantages of being free of power output, low in construction cost, convenient to operate and maintain, outstanding in economic and environmental benefits and the like.

Description

technical field [0001] The invention relates to an ecological system for comprehensively treating rural rain pollution in hilly areas, and specifically belongs to the technical field of wastewater treatment. Background technique [0002] With a large rural population in my country, the random discharge of untreated or improperly treated rural domestic sewage is very common, causing serious impacts on the rural living environment and the health of residents, and exacerbating the deterioration of the water quality of rivers and lakes. It is the main problem in my country's current water environment governance one. With the continuous advancement of my country's new rural construction work and the continuous improvement of public environmental protection awareness, rural domestic sewage treatment has gradually become a hot spot. In 2018, the Central Office and the State Office issued the "Three-Year Action Plan for the Improvement of Rural Human Settlement Environment", which c...
