Abstract

The invention provides a phosphorus removal system for sewage treatment. The system comprises a micro-electrolysis phosphorus removal tank body, a sand filtration tank body and a self-priming pump device; the self-priming pump device comprises a self-priming pump, a first pipeline and a second pipeline, and the self-priming pump is communicated with the first pipeline and the second pipeline separately; the micro-electrolysis phosphorus removal tank body comprises a first hollow tank body and a fixed bed, the fixed bed is formed by a plurality of hollow pipes, and each hollow pipe is filled with micro-electrolysis filler; the fixed bed is arranged at the bottom of the first hollow tank body, and the first hollow tank body is provided with a first water inlet and a first water outlet; one end of the first pipeline penetrates through the first water outlet and enters the hollow tank, the sand filtration tank is provided with a second water inlet and a second water outlet, and the secondpipeline is communicated with the second water inlet. The phosphorus removal system for sewage treatment is convenient to maintain and manage in the whole process and does not need chemical addition,and phosphorus in sewage can be removed more effectively due to the fact that the sewage is treated twice.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a phosphorus removal system for sewage treatment. Background technique [0002] In the field of sewage treatment, especially in the field of rural sewage treatment, the removal of total phosphorus is an important sewage treatment project. The commonly used method is to add polyaluminum chloride, ferric chloride, etc., but the dosage cycle of this method is short, but This method has a short dosing cycle and is prone to secondary pollution. In addition, rural sewage is widely distributed. In the absence of professional and technical personnel for management and maintenance of rural sewage treatment, maintenance costs are greatly increased. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the purpose of the present invention is to provide a phosphorus removal system for sewage treatment, which can solve the problem that the existing method...
