Phosphorus removal device for domestic sewage

Abstract

The invention relates to a phosphorus removing apparatus, in particular, a household sewage phosphorus removing apparatus. The invention aims to provide a household sewage phosphorus removing apparatus, which has a strong phosphorus removing performance, is capable of precisely removing phosphorus, does not waste raw materials, and can remove the stinky smell of household sewage at the same time.In order to solve the abovementioned technical problem, the invention provides a household sewage phosphorus removing apparatus, which comprises a processing box, inclined plates, a water outlet pipe,a first valve, a water inlet pipe, and a first non-return valve. Inclined plates are horizontally and symmetrically arranged in the bottom of the processing box. The water outlet pipe is arranged inthe middle of the bottom of the processing box. The lower end of the water outlet pipe is provided with the first valve. The upper part of the left wall of the processing box is provided with the water outlet pipe. The first non-return valve is arranged in the water inlet pipe. The apparatus has the advantages that the phosphorus removing performance is strong, the phosphorus can be removed precisely, raw materials are not wasted, at the same time, the stinky smell of household sewage is eliminated, and a rubber sleeve can protect a fixed ring from being destroyed by household sewage.

Description

technical field [0001] The invention relates to a phosphorus removal device, in particular to a domestic sewage phosphorus removal device. Background technique [0002] Domestic sewage is mainly various detergents and sewage, garbage, feces, etc. used in urban life, and most of them are non-toxic inorganic salts. Domestic sewage contains a lot of nitrogen, phosphorus, sulfur, and many pathogenic bacteria. Domestic sewage is also Low-temperature heat sources and methane generation sources are even more prospected oil and gas fields. [0003] Phosphorus removal refers to the removal of phosphorus in sewage. Phosphorus exists in the form of phosphate in sewage, so it actually refers to the removal of phosphate. Phosphorus removal in domestic sewage is divided into primary sedimentation, secondary sedimentation and chemical precipitation. Chemical precipitation treatment is Add calcium, aluminum or iron compounds such as lime, alum, ferric chloride, etc. to the sewage, and reac...
