Sewage treatment plant for environmental protection
Technical Field
The invention relates to the technical field of sewage treatment, in particular to an environment-friendly sewage treatment device.
Background
The municipal sewage is a common water pollution, the municipal sewage treatment process generally determines the treatment degree of the sewage and a corresponding treatment process according to the utilization or discharge direction of the municipal sewage and considering the natural purification capacity of a water body, and the treated sewage, whether used for industry, agriculture or recharging and supplementing underground water, must meet the relevant water quality standards issued by the state.
In a sewage treatment system, a flocculation technology is often used for treating sewage, so that suspended particles in water or liquid are gathered and enlarged or form floccules, thereby accelerating the coagulation of particles and achieving the aim of solid-liquid separation. In the prior art, most of the sewage treatment plants are provided with a stirring device at the central position of a sewage pool, the output end of the stirring device is provided with a stirring sheet, and the sewage is stirred by the stirring sheet, but the positions of most of the stirring sheets are fixed and unchangeable, and because the volume of the sewage introduced into the stirring pool is indefinite, when more sewage is introduced into the pool body, the stirring sheet is positioned in the deep part of the sewage to stir the sewage, but the sewage on the upper layer cannot be effectively stirred, so that the impurity-containing substances in the sewage cannot be effectively mixed with a flocculating agent; and when the sewage that lets in is less, when not submerging the stirring piece, the stirring piece also can't carry out effective stirring to sewage, has restricted agitating unit's normal use.
