Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0021] refer to Figure 1-2 , a buried biochemical sewage treatment method, comprising the following steps:

[0022] S1: Solid-liquid separation, inclined from top to bottom, and the mesh aperture is successively reduced. The multi-layer filter screen is used for solid-liquid separation of sewage. A solid recovery tank is installed at the lower end of the filter screen to adjust the pH of the sewage to neutral, and the sewage is pumped into the drain. In the oxygen pool;

[0023] S2: Anaerobic microbial treatment, the sewage is treated with oxygen consumption in the anaerobic tank, and anaerobic microorganisms are added to the sewage to decompose the high-concentrat...

Abstract

The invention discloses a buried biochemical sewage treatment method, which comprises the following steps of: S1, solid-liquid separation: sequentially and obliquely arranging a plurality of layers offilter screens from top to bottom to perform solid-liquid separation on sewage, arranging a solid recovery tank at the lower ends of the filter screens, adjusting the pH value of the sewage to be neutral, and pumping the sewage into an anaerobic tank. Multi-layer solid-liquid separation is carried out on sewage; solid impurities in the sewage are reduced to the maximum extent; high-concentrationorganic wastewater is treated by anaerobic microorganisms, then organic substances are treated by aerobic microorganisms, residual organic matters are treated by an air flotation method, inorganic impurities are absorbed by sandstone, straws and silt, and residual water is subjected to emergent aquatic plant absorption treatment and biological diversification treatment, so that the treatment efficiency is improved, and the sewage residual degree is low.

Description

technical field [0001] The invention relates to the technical field of sewage biochemical treatment, in particular to an underground biochemical sewage treatment method. Background technique [0002] Sewage biochemical treatment is a method of using the metabolism of microorganisms to transform organic pollutants in dissolved and colloidal states into harmless substances in order to achieve purification. It can be divided into aerobic biological treatment method and anaerobic biological treatment method. The former mainly includes activated sludge method, biofilm method, oxidation pond method, sewage irrigation and so on. [0003] The existing treatment methods have a single treatment method and cannot use biodiversity to treat sewage, so the treatment efficiency is low, and the sewage discharge cannot meet the standard. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present invention proposes an underground b...
