Abstract

The invention discloses a vertical low-energy consumption and internal-circulation integral sewage treatment apparatus. The apparatus comprises a gas stripping zone, an aerobic zone, an anoxic zone and an anaerobic zone which are sequentially arranged from top to bottom, the gas stripping zone is provided with a reflux quantity regulator, a center cylinder is arranged under the reflux quantity regulator, the aerobic zone is provided with a filler, an aeration pipeline assembly is arranged under the aerobic zone, the baseboard of the anaerobic zone is provided with a water inlet tube, a three-phase separator is arranged between the anaerobic zone and the anoxic zone, a circulating pump is arranged between the three-phase separator and the bottom of the anaerobic zone, two sides of the gas stripping zone are provided with tilted plate assemblies used for removing mud, and filler layers are arranged above the tilted plate assemblies. The problems of many devices, tedious operation, large occupied area and complex filter structure in the prior art are solved in the invention due to the simple structure of the tilted plate assemblies.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a vertical low energy consumption internal circulation integrated sewage treatment equipment. Background technique [0002] Sewage treatment is usually composed of four series: physical method, chemical method, physical chemical method and biochemical method. Most of the whole sewage treatment process can only be completed by two or more methods. The equipment is mainly building structures. , The main unit is a single unit supplemented by electromechanical equipment, which has the problems of large area, high investment, high operating cost, poor load resistance, low response efficiency, backward management, and low equipment efficiency. At present, the treatment of sewage has been using a similar process route, such as the traditional activated sludge method, developed to the A / O process and the A2 / O process, the essence is to increase the anaerobic (anoxic) b...
