Problems solved by technology

However, rural domestic sewage has the characteristics of many points, wide areas, relatively scattered, good biochemical properties, and low treatment cost, so that we cannot copy the existing treatment technology of urban sewage treatment plants, but should adopt the characteristics of rural sewage treatment in my country. sewage treatment technology
my country's rural sewage treatment has just started, and the existing domestic sewage biogas purification tanks, land infiltration, artificial wetlands and other rural sewage treatment technologies have problems such as low nitrogen and phosphorus removal rates and secondary pollution.

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the embodiments of the accompanying drawings.

[0016] Such as figure 1 , figure 2 As shown, the rural domestic sewage filter-soil tank ecological treatment system is composed of a multi-stage baffle hydrolysis tank (1), a water pump (2), a filter tank (3), and a soil tank (4). Wherein the multi-stage baffle hydrolysis tank (1) includes baffles (5) and packing bundles (6); the filter tank (3) includes nozzles (7) and ceramsite (8); the soil tank (4) includes plants (9) ), soil (10), geotextile (11), water distribution pipe (12), water distribution tray (13), phosphorus adsorption filler (14), water collection pipe (15).

[0017] The filler bundle (6) in the multi-stage baffle hydrolysis tank (1) is a plastic soft filler bundle, and the volume of the filler bundle (6) is 1 / 4 to 1 / 3 of the volume of the multi-stage baffle hydrolysis tank (1). 3.

[0018] The particle size of the ceramsite (8) i...

Abstract

The invention discloses a filter tank-soil groove ecological treating system and process for rural domestic sewage. The treating system comprises a multistage baffling hydrolytic bond, a water pump, a filter tank and a soil groove, wherein, the multistage baffling hydrolytic bond comprises a baffle plate and a packing bundle, the filter tank comprises nozzles and ceramists, and the soil groove comprises plants, soil, earthwork cloth, a water distributor, a water distributing disc, a phosphorous adsorption filling material and water collecting pipe. According to the treating process, sewage tobe treated flows automatically from a water inlet into the multistage baffling hydrolytic bond for treatment, treated sewage flows into the filter tank and then to the soil groove for treatment, and treated effluent is discharged after reaching the standard. High efficiency nitrogen and phosphorus removal technology is employed in the treating system, and the treating system has the advantages ofa good treating effect, low operating cost and convenient maintenance, providing a novel treating technology for rural domestic sewage.

Description

Technical field: [0001] The invention belongs to the technical field of rural domestic sewage treatment, and relates to a rural domestic sewage filter tank-soil tank ecological treatment system and technology. Background technique: [0002] With the rapid development of my country's economy, environmental pollution has become increasingly serious. The environmental problems of urban domestic sewage have attracted great attention, urban sewage treatment plants have emerged as the times require, and point source pollution caused by urban sewage and domestic sewage has been effectively controlled. However, rural domestic sewage has the characteristics of many points, wide areas, relatively scattered, good biochemical properties, and low treatment cost, so that we cannot copy the existing treatment technology of urban sewage treatment plants, but should adopt the characteristics of rural sewage treatment in my country. sewage treatment technology. my country's rural sewage trea...
