Abstract

The invention discloses a preliminary recirculating filtering device for sewage treatment and a use method and relates to the technical field of sewage treatment. The device comprises a bracket, wherein a first filter tank and a second filter tank are fixed to the top of the bracket, the side face of the first filter tank communicates with the second filter tank through an overflow pipe, an impurity filter screen is fixed to the top of the internal wall of the first filter tank, an impurity discharging mechanism matched with the impurity filter screen is fixed to one side face of the first filter tank, a dosing pipe penetrates through the other side face of the first filter tank, a supporting plate is fixed to the side face of the first filter tank, and a stirring mechanism is fixed onto the supporting plate. According to the device and the method, through carrying out recirculating precipitation treatment on sewage, chemical-treated sewage can be subjected to precipitation treatment again, so that suspended pollutants are effectively removed from the sewage, and the efficiency of sewage treatment is increased while sewage treatment effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a preliminary circulating filter device for sewage treatment and a use method thereof. Background technique [0002] With the development of science and technology, environmental pollution is an increasingly serious problem, among which sewage treatment is the most important of many environmental problems. Sewage includes industrial sewage and domestic sewage. If the sewage cannot be completely purified and discharged directly, it will re-enter the earth's water cycle system, destroying the ecological environment, and the sewage will also enter the human body and affect human health. [0003] Existing sewage treatment and filtering devices are composed of coagulation sedimentation tanks and filter tanks, which not only have many structures and occupy a large area, but also have a complicated use process and low efficiency in the initial removal of pollutants....
