Abstract

The invention discloses urban sewage treatment equipment which comprises a denitrification tank, a dephosphorization tank and a dosing tank, a first motor is fixedly mounted at the center of the top surface of the denitrification tank, and the output end of the first motor penetrates through the denitrification tank and is rotationally connected with a first stirring paddle. The urban sewage treatment equipment has the beneficial effects that sewage is sequentially introduced into the denitrification tank, the dephosphorization tank and the dosing tank, and then the first motor and the second motor are started respectively, so that the first stirring paddle and the second stirring paddle are enabled to disturb the sewage in the denitrification tank and the dephosphorization tank respectively, bacteria (a biological filter material carrying anaerobic denitrification bacteria is arranged in the denitrification carrier disc, and a biological filter material carrying aerobic bacteria is arranged in the dephosphorization carrier disc) in the denitrification carrier disc and the dephosphorization carrier disc are in full contact with sewage; the sewage is subjected to secondary treatment in a medicament form after biological treatment by gradually adding enitrification and dephosphorization agents into the dosing tank so that the biological treatment and the medicament treatment of the sewage are synchronously carried out.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to urban sewage treatment equipment. Background technique [0002] With the development of cities, the increase of population, and more and more industrial sewage and domestic sewage, sewage treatment has become a major problem that people need to solve immediately. Sewage treatment refers to the water quality requirements for sewage to be discharged into a certain water body or reused. The process of purifying it, sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. There are many treatment methods, among which the use of microorganisms to remove nitrogen and phosphorus in wastewater is a very environmentally friendly way. Microbial denitrification is the ...
