Problems solved by technology

[0006] In order to solve the problem that when the traditional AB method sewage treatment system is applied, the quality of the effluent from the sewage plant is difficult to guarantee, and the content of nitrogen and phosphorus in the treated sewage is relatively high, which cannot meet the requirements of the existing sewage discharge standards, and the equipment is expensive, Short service life and inconvenient maintenance

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] figure 1 It is a flowchart structure diagram of a sewage treatment system determined by the present invention. As shown in the figure, the water treatment method is divided into three sections: pretreatment section, adsorption deposition section, and biodegradation section.

[0025] The pretreatment section includes grid 1 and grit chamber 2. The sewage first passes through the grid 1 to remove coarse suspended solids and sundries, and then enters the grit chamber 2, where the inorganic particles contained in the sewage are removed through physical settlement to protect subsequent equipment. Of course, in this pretreatment section, other methods can also be used to initially remove coarse suspended solids and impurities in the water, such as filtration or air flotation, which can also achieve the same effect of removing impurities and realize t...

Abstract

The invention relates to a sewage treatment system, which comprises a grid for filtering suspended substances and impurities in the sewage, a sand sedimentation pond used to separate the sediment and inorganic granules in the sewage, a middle sedimentation pond and an absorption pond used to absorb the contaminations in the sewage; wherein the grid and the sand sedimentation pond are connected each other to perform the pretreatment of the sewage, the absorption pond and the middle sedimentation pond are connected each other to perform absorption sedimentation treatment of the contaminations in the sewage; the invention is characterized in that: the sewage treatment system also comprises an anoxic pond and an aerobic pond that are connected each other, the aerobic pond is added with biological fillings, entire system solves effectively the problem of inadequate carbon source when denitrifying in the original AB water treatment system, thereby enhancing the effect of removing total nitrogen, moreover the invention has convenient management, no needing frequent maintenance, no needing frequent process parameter adjustment according to sludge retaining time and sludge concentration.

Description

【Technical field】 [0001] The invention relates to a sewage treatment system, in particular to a water treatment system which uses HYBAS (hybrid biofilm-activated sludge) aerobic process to upgrade the original urban sewage treatment system. 【Background technique】 [0002] AB method sewage treatment process is the abbreviation of Adsorption-Biodegradation (Adsorption-Biodegradation). It was created by Professor Bohnke of RWTH Aachen University in Germany in the mid-1970s to solve the traditional secondary biological treatment system. Since the early 1980s, it has been used as a sewage treatment process for production practice. [0003] The whole system of AB process is divided into three sections: pretreatment section, adsorption deposition section, and biodegradation section. The principle of removing pollutants in the pretreatment section is through physical interception and sedimentation. The adsorption deposition section is composed of an adsorption tank and an interme...
