Description

A kind of sewage purification equipment

technical field

The utility model relates to the technical field of environmental protection equipment, in particular to a sewage purification equipment.

Background technique

Sewage treatment refers to sewage purification, which refers to the process of treating sewage to achieve the quality of discharging a certain water body or reusing it. In modern life, especially with the deepening of urbanization, the living density of the population continues to increase, so the domestic wastewater and some other sewage in the population are also increasing. At the same time, in order to find more space in the existing living environment, urban construction is also increasingly developing towards high-rise buildings and underground buildings. But the problem of urban pollution, especially the problem of domestic sewage is also becoming more and more serious.

Sewage purification can be divided into primary treatment, secondary treatment and tertiary treatment according to the degree of treatment. The primary treatment is mainly to remove the suspended solid matter in the sewage. The wastewater after the primary treatment is still not suitable for discharge and must be treated in the secondary treatment. The main task of the secondary treatment is to substantially remove colloidal and dissolved organic matter in the sewage. Generally, the sewage after the secondary treatment can meet the discharge standard. The purpose of the tertiary treatment is to further remove certain special pollutants, such as fluoride removal, phosphorus removal, etc., which belongs to advanced treatment.

Most of the existing sewage purification equipment adopts the sedimentation method. The defect is that there will be some precipitated impurities mixed in the water flow, and the treatment effect is poor. After the primary treatment, there are still suspended or precipitated solid impurities in the sewage. These solid impurities will enter the secondary treatment device with the sewage, affecting the treatment effect of the secondary or tertiary treatment device, and at the same time reducing the service life of the secondary or tertiary treatment device. In addition, the settled sludge is not easy to discharge, which also affects the sewage Processing efficiency.
