Abstract

The invention discloses a device and a preparation method for preparing polyferric sulfate by microbial catalysis. The device is arranged in a sewage treatment plant, and the device includes a bioreactor. The storage tank is connected to the sediment storage tank, the PFS product storage tank is connected to the inlet of the secondary settling tank through the delivery pipeline, and the secondary settling tank and the water outlet are connected to the bioreactor through the water inlet pipe. An aeration device is installed on the bioreactor, and the aeration device includes an air pipe and an aeration head, the aeration head is inside the bioreactor, and the other end of the air pipe is connected with the aeration system in the sewage treatment plant. The advantage of the present invention is that the synthesis device is arranged in the sewage treatment plant, so that the prepared product is directly transported to the sewage treatment plant for use through the conveying pipeline, effectively saving the transportation cost.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a device and a preparation method for preparing polyferric sulfate by microbial catalysis. Background technique [0002] Polyferric sulfate (PFS) is an inorganic polymer flocculant, and its liquid is reddish brown. Polyferric sulfate introduces hydroxyl groups into the network structure of iron molecular clusters, and forms multi-nuclear complex ions with OH- bridging. Polyferric sulfate is widely used in the purification treatment of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dehydration, etc. Compared with traditional flocculants such as ferric chloride, aluminum sulfate, and ferric sulfate chloride, polymerized ferric sulfate has the advantages of less dosage in the purification process, wide pH range, less corrosion to equipment, high impurity removal rate, and low residue concentration , good dehydrat...
