Embodiment Construction

[0028] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0029] refer to figure 1 , a decentralized sewage multi-layer soil ecological treatment device, including a raw water pool 1, a sedimentation tank 2, a contact oxidation tank 3, a biological filter 4, a sedimentation tank 2 5, a flow regulation tank 6, a soil treatment tank 7 and a collection tank connected in sequence The pool 8, the raw water pool 1, the contact oxidation pool 3, the biological filter pool 4, and the soil treatment pool 7 are all connected to the blower through pipelines. Both sedimentation tank one 2 and sedimentation tank two 5 rely on gravity to settle sludge and discharge the sludge to sludge drying tank 9 for natural filtration and drying, and the filtrate returns to raw water tank 1. The lower part of the biological filter 4 is filled with suspended filler, and the biological filter 4 is connected to the contact oxidation tank 3 ...

Abstract

The invention relates to a dispersive sewage multilayer soil ecological treatment device which comprises a raw water tank, a first sedimentation tank, a contact oxidation tank, a biological filter tank, a second sedimentation tank, a flow regulating tank, a soil treatment tank and a water collection tank which are connected in sequence,, wherein the raw water tank, the contact oxidation tank, the biological filter tank, and the soil treatment tank are respectively connected to an air blower, and the soil treatment tank comprises a tank body, a water distributing pipe, a water passing layer, a soil layer, a ventilation layer, an air layer, a quartz sand layer, a cobblestone layer and a water collecting pipe. A treatment method comprises the following steps of: (1) lifting sewage to the first sedimentation tank for anaerobic sedimentation after collecting the sewage by using the raw water tank; (2) entering the contact oxidation tank, and then making discharged water pass through the biological filter tank; (3) after passing through the second sedimentation tank, making the discharged water enter the flow regulation tank, and then delivering the discharged water to the soil treatment tank; and (4) intermittently performing water intake and ventilation on the soil treatment tank. The invention effectively improves the osmotic coefficient of a soil layer, the hydraulic loading is up to above 2.0-8.0m and is increased by dozens of times higher than the traditional soil treatment method, and the treatment efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a decentralized sewage multi-layer soil ecological treatment device and method. Background technique [0002] my country is a country that lacks water resources. With the development of the economy and the improvement of people's living standards, the consumption of fresh water resources and the corresponding discharge of domestic sewage and industrial wastewater continue to increase. Due to backward economic and technical conditions, pollution has not been achieved. Timely control, nationwide water pollution is becoming increasingly serious. The direct discharge of a large amount of sewage without effective treatment has caused a series of environmental problems such as river pollution and eutrophication of lake water, which has seriously deteriorated the ecological environment of my country's surface water bodies. Serious water pollution and shortage of water resou...
