Ecological type manual fast-permeability sewage processing system

Abstract

The invention discloses an ecological type manual fast-permeability sewage processing system, which is used for purifying and processing sewage. Suspended solid in the sewage can be firstly intercepted by a grid tank (1), and the sewage can then flow into a micro aeration tank (3) through a drainage pipeline which is arranged at the lower part of a regulating tank (2) after the water quality and the water quantity are subjected to equalizing regulation by the regulating tank (2); and the sewage can flow into an ecological fast-permeability tank (4) to be subjected to purification processing after being subjected to aeration processing by the micro aeration tank (3), is collected by a water collecting pipeline (7) which is arranged at the bottom, and can be discharged after flowing into a post-positioned denitrification tank (5) and being subjected to denitrification processing. The ecological type manual fast-permeability sewage processing system disclosed by the embodiment of the invention has the advantages of being less in field limit, less in occupied area, high in hydraulic loading, good in water outlet efficiency and easy in operation and management; and due to the implementation of the ecological type manual fast-permeability sewage processing system, the removing ability for TN (Total Nitrogen) and TP (Total Phosphorus) is increased, each water outlet water quality index is stably up to the level A emission standard, the investment cost and the running cost can be reduced, and the ecological landscape effect can be increased.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an ecological artificial quick-seepage sewage treatment system. Background technique [0002] With the enhancement of people's awareness of environmental protection, sewage treatment has become a key issue of concern to the governments of various countries. There are three main sources of sewage in our country, namely, decentralized domestic sewage in township residential areas, centralized domestic sewage in urban living areas, and sewage generated in industrial production processes. The use of sandy land to purify sewage is the most commonly used traditional sewage treatment method. It uses natural sandy land with good permeability as a percolation tank. When sewage passes through a percolation tank, it will go through a series of complex physical and chemical processes. and biological changes, thereby being purified. However, this sewage treatment method has at least the foll...

AI Technical Summary

Problems solved by technology

[0003] First, the traditional method of using sandy land to purify sewage is subject to strict site restrictions, because the permeability of the infiltration tank is directly related to the ability of sewage treatment, and natural sandy land with good permeability must be selected;

[0004] Second, the traditional method of using sandy land to purify sewage occupies too large an area, which is very unfavorable for our country with a large population and limited available land;

[0005] Third, due to the non-homogeneous permeability of natural sandy land, the hydraulic load of traditional sewage treatment methods (the so-called hydraulic load refers to the amount of wastewater that can be treated per unit volume of filter material or unit area per day, and its unit is cubic meters (wastewater) / cubic meter (filter material) · day, or, cubic meter (wastewater) / square meter (pool) · day, usually written as m / d (m 3 / m 2 d)) lower;

[0006] Fourth, the traditional sewage treatment method is to TN (TN is the abbreviation of total nitrogen, translated as total nitrogen; refers to the total amount of various forms of inorganic nitrogen and organic nitrogen in water in this field, including NO 3- , NO 2- and NH 4+ Such as inorganic nitrogen and organic nitrogen such as protein, amino acid and organic amine, calculated in milligrams of nitrogen per liter of water; often used to indicate the degree of water pollution by nutrients) and TP (TP is the abbreviation of total phosphorus, translated as total phosphorus ; In this field, it refers to the total amount of various forms of inorganic phosphorus and organic phosphorus in water, calculated in milligrams of phosphorus per liter of water; it is often used to indicate the degree of water pollution by nutrients) does not have a good removal effect
