Abstract

The invention discloses a device and preparation method for preparing polyferric sulfate through microbial catalysis. The device is arranged in a sewage treatment plant, the device comprises a bioreactor, the bioreactor is respectively connected with a PFS product storage tank and a precipitate storage tank through a liquid outlet pipe and a discharge pipe, The PFS product storage tank is connected with an inlet of a secondary sedimentation tank through a conveying pipeline, and the secondary sedimentation tank and a water outlet are connected with the bioreactor through a water inlet pipe. An aeration device is arranged on the bioreactor, the aeration device comprises an air pipe and an aeration head, the aeration head is arranged in the bioreactor, and the other end of the air pipe is connected with an aeration system in a sewage treatment plant. The device has the advantages that a synthesis device is arranged in a sewage treatment plant, so that the prepared product is directly conveyed into the sewage treatment plant for use through a conveying pipeline, and the transportation cost is effectively saved.

Description

Technical field[0001]The present invention belongs to the field of environmental engineering, and more particularly to a microorganism catalytic device and a method of preparing a polymer sulfate.Background technique[0002]Polymeric sulfate (PFS) is an inorganic polymer flocculant, which is reddish brown. The polymeric sulfate is introduced into a hydroxyl group in a network structure of a feroconus cluster to form a multi-core ion in an OH-frame bridge. The polymerization of iron sulfate is widely used in drinking water, industrial water, various industrial wastewater, urban sewage, sludge dehydration, and the like purification treatment. Compared with traditional flocculant, iron sulfate, aluminum sulfate, iron chloride, etc., is small, using a wide range of pH, small in the range of pH, low impurity removal rate, low residue concentration , Good dehydration, non-toxic and other advantages.[0003]Since the early 1980s, my country has been developed, and a large number of studies hav...
