AI Technical Summary
Technical Problem
Existing urban sewage treatment facilities cannot effectively remove grease and fibrous impurities in the pretreatment stage, resulting in low subsequent treatment efficiency, unstable effluent quality, and grease discharge that can easily lead to eutrophication of water bodies.
Method used
It adopts a conical flow guide plate and a multi-stage filtration structure, combined with an electrostatic adsorption net, to achieve oil-water separation and pollutant removal through a combination of physical interception and biochemical degradation.
Benefits of technology
It improves oil-water separation efficiency, reduces energy consumption and maintenance costs, extends equipment life, improves effluent quality, and reduces pollutant load on the biochemical treatment unit.

Abstract
The invention relates to the technical field of sewage treatment, in particular to an urban domestic sewage treatment device which comprises a treatment pump station, a flange water inlet pipe opening is formed in the top of the outer arc surface of the treatment pump station, and a conical bucket type flow guide junction plate is connected to the bottom, close to the flange water inlet pipe opening, of the inner arc surface of the treatment pump station. A water inlet is formed in the middle of the upper surface of the conical bucket type flow guide junction plate, the conical bucket type flow guide junction plate is arranged in an inner layer and an outer layer, an arched end part is arranged in the conical bucket type flow guide junction plate, water flow is guided to form a slow flow state through a special structural design, sufficient reaction time is provided for coalescence of tiny oil drops, and the reaction efficiency is improved. By utilizing the physical characteristic that the density of grease is smaller than that of water, the oil droplets can naturally float upwards and form a stable floating oil layer, the whole oil-water separation process can be completed only by the action of gravity without additional power drive, the oil-water separation efficiency is effectively improved, and the oil-water separation efficiency is improved. The operation energy consumption and the maintenance cost of the device are reduced.
