Micro-power municipal sewage treatment equipment and process

Abstract

The invention discloses micro-power municipal sewage treatment equipment which comprises a tank body as well as a micro-power aeration system, wherein a water inlet tube and a water outlet tube are respectively arranged at the upper parts of two sides of the tank body; a partitioning plate parallel to the tank wall is arranged on one side of the tank body, close to the water inlet tube; the partitioning plate is used for partitioning the tank body into a water inlet area and a reaction area of which the bottoms are mutually communicated; an active sludge layer, a suspension filler layer, a light ceramsite layer and a clean water layer are sequentially arranged in the reaction area from bottom to top in sequence; the micro-power aeration system comprises an aeration pipeline arranged on the active sludge layer, an aerator connected with the aeration pipeline and a power device arranged outside the tank body and used for supplying power to the aerator. The invention further discloses a process for sewage treatment by using the equipment. The equipment and the process disclosed by the invention have the advantages of good treatment effect, high efficiency in nitrogen and phosphorus removal, sludge loss prevention, sludge dead angle prevention, small occupied area, investment preservation, low operation cost, low energy consumption, convenience in operation and management, flexibility in process and the like.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a micro-power township sewage treatment equipment and process. Background technique [0002] In towns and villages, a large amount of domestic sewage is produced every year. If it is discharged directly without treatment, it will cause serious environmental pollution problems, directly threaten the health of the people, and restrict the scientific development of the economy. Domestic sewage treatment in towns and rural areas in my country started late, and due to scattered water sources, difficulty in laying pipe networks, and low technical and management levels of employees, the sewage treatment rate in towns and rural areas is low, and sewage treatment is difficult. Therefore, it is necessary to According to local conditions, seek economical, efficient, energy-saving and convenient operation and management of sewage treatment solutions. [0003] At present, the technologies and ...

Problems solved by technology

The biofilter requires regular backwashing, which is inconvenient to maintain and has high operating costs; the high-efficiency algae pond covers a large area and is significantly affected by environmental factors. When the temperature is too high in certain months of the year or the temperature is low in winter, Because the growth of algae is inhibited, the treatment effect is affected; artificial wetlands also have the disadvantage of large area, and are easily affected by diseases and insect pests, and the technology is not mature enough; Oxidation ditch is suitable for large water volume, not suitable for small water volume, and the area occupied Relatively large, high operating costs, and unstable effluent quality during long-sludge age operation
