Description

Sewage treatment prefilter

Technical Field

The utility model relates to a sewage treatment prefilter belongs to sewage treatment device technical field.

Background

The domestic sewage is the wastewater discharged by people in daily life activities, the wastewater is mainly polluted by domestic waste and human excrement, and the quantity, the components and the concentration of pollutants are related to the living habits and the water consumption of people. Domestic sewage generally does not contain toxic substances, but it has conditions suitable for the propagation of microorganisms, contains a large amount of bacteria and pathogens, and has a certain hazard from a hygienic viewpoint.

As the urban population is continuously increased, the problem of urban domestic wastewater treatment is increasingly highlighted. And the urban environment and the construction thereof are always influenced because of the technical lag, the fund shortage and the great treatment difficulty. If the problems are not solved as soon as possible, the pollution is more serious and the influence is worse as the water consumption is continuously increased along with the advance of urbanization.

The urban domestic sewage is different from industrial wastewater, can be prevented or moved by industrial enterprises, and solves the source. The urban domestic sewage mainly comes from a series of urban public places and public facilities such as families, schools and businesses. The wide and inevitable nature of its origin also makes the treatment of sewage face a regional trend. The pollutants of urban domestic sewage are more of the eight flowers, but the main contents of the pollutants are mainly organic matters, wherein the domestic garbage such as starch, protein, sugar, mineral oil and the like is more, wherein the BOD2 (biological oxygen demand), CODC2 (chemical oxygen demand), TkN (Kjeldahl nitrogen), TP (total phosphorus), TN (total nitrogen) and the like are also higher, and the pollutants are easy to cause eutrophication of water bodies after being discharged into the water bodies, so that a large amount of algae grow and reproduce, and the red tide and the water bloom which are usually seen are related to the pollutants. And when the temperature is in seasons, the algae die instead of being used, the water in the water area is rotten and smelly, and the water quality is deteriorated, so that the expression characteristics and the content of specific components of the urban domestic sewage are ensured, and people can know all the links more clearly when treating the urban domestic sewage.

The direct discharge of waste water can cause huge harm to the environment, so need handle waste water when discharging waste water, waste water treatment's first step is just filtering, filter equipment is all fixed in the waste water treatment equipment that has on the market, this just leads to when handling waste water, the filter screen blocks up easily, reduce the filter effect, still need the manual work to change the clearance behind the filter screen jam, and impurity after the filtration also needs the manual work to clear up, work efficiency is low, operating personnel's intensity of labour is big.
