Coagulation gravity fiber filter device

Abstract

The invention belongs to the field of sewage treatment devices, and in particular relates to a coagulation gravity type fiber filtering device. A partitioning plate is arranged between a coagulation basin and a maturation pond in such a manner that the bottoms of the coagulation basin and the maturation pond are communicated with each other; a stirring device is arranged inside the coagulation basin; a water inlet tube is arranged on one side of the coagulation basin; the water inlet tube is communicated with a dosing device; a water inlet cavity, a filtering cavity, a water generation cavity and a backwash water discharge cavity are respectively formed inside the filtering pond; the water inlet cavity is communicated with the maturation pond; water inlet valves are arranged at the top of the water inlet cavity; a fiber filtering device is mounted inside the filtering cavity; a fiber beam control device is connected with the top of the filter filtering device; the fiber filtering device is communicated with the water generation cavity through an inner cavity; a water outlet is formed in the side wall of the water generation cavity; backwash aeration devices are arranged at the bottom on the outer side of the fiber filtering device; the backwash aeration devices are connected with a fan through a backwash air pipeline; backwash water discharge valves are arranged on the backwash water discharge cavity. The coagulation gravity type fiber filtering device is good in effluent quality, stable in treatment effect, high in impact resistance burden, small in medicine use amount, free of water supply and backwash water pump, and low in energy consumption.

Description

technical field [0001] The invention relates to a coagulation gravity fiber filter device which does not need sedimentation and direct coagulation reaction filtration, and belongs to the field of sewage treatment devices. Background technique [0002] The removal of SS (suspended solids) and phosphorus at the end of the existing sewage treatment is mainly achieved by adding chemical agents, coagulation reaction + sedimentation + filtration to remove SS and chemical phosphorus removal. Because it must be precipitated before filtering to enter the filter device, it has the disadvantages of large floor space, high operating costs, and high investment. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a high-efficiency, low energy consumption, small footprint, good effluent water quality, stable treatment effect, no need for precipitation after coagulation, and directly filter SS and phosphorus through a gravity fiber...
