Abstract

The invention provides a chemical and biological sewage treatment device, which comprises a shell, a central cylinder, a central cylinder supporting frame, a composite filtering material, a filtering material supporting plate, a water distributor, aerators, a water collection tank, a water outlet pipe, a water inlet pipe, a chemical feed pipe and a dredge pipe, wherein the central cylinder is arranged in the shell; the water outlet pipe is connected with the water collection tank; the water inlet pipe is arranged on the top of the shell; the dredge pipe is arranged at the bottom of the shell; the chemical and biological sewage treatment device is characterized in that active sludge is filled in the central cylinder; the aerators are micro-porous aerators; and the micro-porous aerators are arranged both inside and outside the lower end in the central cylinder and are positioned on the central cylinder supporting frame. According to the chemical and biological sewage treatment device, chemical coagulation, chemical-biological oxidation, filtration and adsorption effects are finished in the same tank; and the chemical and biological sewage treatment device has the advantages of rational and compact structure, good effluent quality, high treatment efficiency, low operation cost, high adaptability and easiness in operation and management.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage chemical and biological treatment device. Background technique [0002] The basic methods of sewage treatment include physical methods, chemical methods, biochemical methods, filtration methods, etc., which are often combined in series with these methods in the practice of industrial or urban sewage treatment. For example: coagulation + biochemical + filtration, biochemical + coagulation + filtration, coagulation + biological aerated filter, biochemical + membrane treatment, etc. Each of these processes has its own characteristics, but the disadvantage is that the process is long or the operating cost is high , each processing unit technology cannot cooperate. How to organically combine the technologies of each treatment unit to complement each other's advantages and achieve the effects of good effluent quality, high treatment efficiency, low treatment cost, an...
