Sewage treatment device

Abstract

The invention provides a sewage treatment device which comprises a shell, a support board, a compound filling material in the shell, a water inlet pipe, a water outlet pipe, a perforation aerator and an air supply device. The sewage treatment device is characterized in that the shell is internally provided with a center barrel in which a water distributor and a micro-electrolysis filling material are arranged, and the micro-electrolysis filling material and the bottom of the center barrel are located on the support board; the water inlet pipe is connected with the water distributor; a water colleting sump which is of a ring shape and is upwardly opened encircles the periphery of the upper part of the center barrel; one end of the water outlet pipe is connected with the water colleting sump, and the other end of the water outlet pipe penetrates through the shell to be led out; a center draft tube the upper and lower ends of which are opened is connected to the lower part of the support board; the center draft tube is internally provided with a doser, and a dosing tube connected with the doser upwardly penetrates through the center barrel and then is led out from the upper part of the shell; and the compound filling material in the shell encircles the periphery of the center barrel and is divided into upper and lower layers to be supported by the support board. The sewage treatment device has a reliable and compact structure; a micro-electrolysis technique and a biological treatment technique as well as a filtration technique are organically combined; and the effluent quality is good, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage processor. Background technique [0002] The treatment of industrial sewage is a hot spot of general concern. Due to the wide variety of industrial sewage, large changes in water volume, high water quality concentration, and complex components, it is difficult to treat. At present, most of the combined treatment processes of conventional technologies are used. These processes often have a long process, high energy consumption in the transfer process, and high operating costs, making it difficult to achieve the ideal treatment effect. In particular, high-salt and high-concentration organic sewage has always been a difficult point to deal with. The organic pollutants in sewage have high concentration, stable structure, and poor biochemical properties. It is difficult to achieve standard discharge by conventional processes, and the treatment cost is high. big pres...
