Distributed sewage disposal device and method

Abstract

The invention belongs to the technical field of sewage disposal and particularly relates to a distributed sewage disposal device and method. The distributed sewage disposal device includes an adjustment pool, a hydrolysis acidification pool, at least four catalytic oxidation pools, an air pipe, an aeration head, fillers, a lifting pump and an air blower; the lifting pump is connected to the adjustment pool, the hydrolysis acidification pool is positioned in one side of the adjustment pool, and the catalytic oxidation pools are positioned on one side of the hydrolysis acidification pool; one end of the air pipe is connected to the air blower, the other end of the air pipe stretches to the bottoms of the catalytic oxidation pools, and the aeration head is installed on the portion, at the bottoms of the catalytic oxidation pools, of the air pipe. The fillers are suspended in the catalytic oxidation pools and positioned above the aeration head. A multilevel catalytic oxidation method is adopted for sewage disposal, the yield of organic remaining sludge almost reaches zero, and the distributed sewage disposal device has the advantages that the effluent quality is great, the process parameters are easy to control, the equipment is compact, the occupied land is small, and automatic control management is easy.

Description

technical field [0001] The application belongs to the technical field of sewage treatment, and in particular relates to a distributed sewage treatment equipment and method. Background technique [0002] As we all know, the most effective process equipment for treating distributed sewage is MBR (Membrane Bioreactor, Membrane Bioreactor). MBR is a new type of water treatment technology that combines a membrane separation unit with a biological treatment unit. Well, it has the advantages of greatly reducing the occupied area and saving civil construction investment, so its number is increasing and its scale is expanding. It has been widely used in the field of water treatment and has played a very important role in alleviating the increasingly serious water pollution in our country. role. [0003] However, in the face of the vast rural areas with scattered residences and no drainage pipe network, MBR technology still has the following shortcomings: [0004] 1) The equipment p...
