Embodiment 1

[0039] Near the new campus of Southwest Jiaotong University - Xipu Town, Pi County, Chengdu City, an artificial rapid infiltration tank was built to treat domestic sewage for a farm family of 3. The initial investment cost of the artificial rapid infiltration tank built for this farmer is about 200 yuan, and the later operation cost is only a small amount of electricity.

[0040] Design scale: Q=38L / d;

[0041] Design hydraulic load: 1.0m / d;

[0042] Water distribution scheme: 4 times of water distribution within 24 hours a day, dosing once every 6 hours, each water distribution time is 1.5 hours, and the drying time is 4.5 hours;

[0043] Percolation medium and thickness of percolation medium layer: The artificial rapid percolation tank is filled with an artificial filter material which is uniformly mixed with granular river sand and sponge iron at a volume ratio of 5:1. The filler of the artificial rapid percolation tank is divided into 3 layers, the bottom filler is grave...

Abstract

The invention discloses a constructed rapid infiltration pond and an application thereof in decentralized treatment of rural domestic sewage. An artificial filter material which is manually configured is filled in the constructed rapid infiltration pond, and is produced by mixing granular river sand and sponge iron according to the volume ratio of 5 to 1. Compared with the prior art, the constructed rapid infiltration pond can effectively improve phosphorus removal efficiency on the basis of effectively degrading and denitriding organic substances, so that the cost is lowest when the outlet water quality standard of sewage achieves the primary A standard in Pollutants Emission Standard of Urban Wastewater Treatment Firm (GB18918-2002).

Description

technical field [0001] The present invention relates to an artificial rapid percolation sewage treatment tank, in particular to a low-cost artificial rapid percolation tank that can improve phosphorus removal efficiency on the basis of effectively degrading organic matter and denitrification, and its application in rural domestic sewage applications in decentralized processing. Background technique [0002] Rural domestic sewage has become one of the main sources of water pollution in rural areas of my country. Due to factors such as scattered sources, backward supporting treatment technology, lack of environmental protection funds, and poor awareness of environmental protection in rural areas, it is almost directly discharged into rivers without any treatment. , reservoirs and lakes, resulting in black and smelly rivers, eutrophication of lakes and reservoirs is a serious problem, and the natural environment, ecological environment and drinking water safety have been serious...
