Monotubular anaerobic-aerobic composite microencapsulation biological fluidized bed automatic control apparatus

Abstract

The invention discloses single cylinder type anaerobic-aerobic composite microencapsulation biological fluidized bed automatic control equipment, wherein an anaerobic fluidized bed body is a reaction area which is, from top to bottom, orderly provided with a water inlet(outlet), a water distribution machine, an electric heating pipe, a grille, an overflow opening, a lighting device, a sampling opening, an automatic detection device and a material feeding and gas exhaust device; water source enters from the bottom of the anaerobic fluidized bed through an ultraviolet sterilizer, and a microbe capsule is driven to keep in fluidized state by water flow; wastewater in the anaerobic fluidized bed directly flows in a pollution discharge pond or an aerobic fluidized bed through the water outlet pipe on the bottom; an aerobic fluidized bed body is similar to the anaerobic fluidized bed body, but the difference lies in that an aeration disk is used to replace the water distribution machine, and the microbe capsule is driven to keep in the fluidized state by air flow; and because channels of the anaerobic fluidized bed and the aerobic fluidized bed are provided inside with one-way valves, the anaerobic fluidized bed and the aerobic fluidized bed can independently work. Under the condition of saving labor, the equipment realizes that the high-concentration polluted wastewater is denitrified and dephosphorized with high efficiency, and the pollution discharge meets the national standards; moreover, the equipment also has the advantages of simple structure and automatic operation.

Description

technical field [0001] The invention belongs to the field of resources and environment, and mainly relates to a single-tube anaerobic-aerobic composite microencapsulated biological fluidized bed automatic control equipment. Background technique [0002] In the context of sustained economic growth and tremendous pressure on resources and the environment, it is the strategic goal of environmental protection during the "Eleventh Five-Year Plan" period to pursue a win-win situation for the environment and the economy while curbing the trend of "increasing environmental pollution". At present, my country's economic development is in the stage of rapid industrialization, and the environmental problems caused by many polluting industries are exacerbating the deterioration of the ecological environment. The present invention aims at the practical problem of difficult removal of organic pollutants in sewage treatment, and develops single-tube anaerobic-aerobic composite microencapsul...

Problems solved by technology

In recent years, most of the many types of carriers developed for biological fluidized beds at home and abroad are inorganic carriers, among which granular activated carbon has better effect and is widely used. However, the common disadvantages of inorganic carriers are high density and energy consumption for fluidization. High, its surface properties, shape and pore structure are difficult to artificially control and transform, so researchers are currently looking for polymer synthesis technology, screening suitable materials to find the best molding process, and developing carriers with excellent comprehensive properties
