Facultative device applied to sewage treatment

Abstract

The invention provides a facultative device applied to sewage treatment. An aeration port is formed in an aeration gas inlet pipeline, an aeration component is arranged at the aeration port, aeration nozzles are formed in tops of aerators, and the bottom of each aerator is connected with an aeration connection pipe; a stirring motor is arranged at one end of a stirring lifting rod, and a stirring head is arranged at the other end of the stirring motor; a sludge lead-out bottom plate on the bottom layer is arranged nearby the bottom end of a main adjusting tank body, a sludge lead-out groove is formed below a sludge water outlet, a lead-out scraper blade sliding rail is arranged at the bottom end of the main adjusting tank body, and a lead-out scraper blade is arranged on the lead-out scraper blade sliding rail; one end of a sewage discharging pipe is connected with a water inlet in the bottom end of an acidic adjustment reflux tower, and an adjustment reflux pipe is arranged in the acidic adjustment reflux tower; a three-way switching valve is arranged at a water outlet; a flocculation filtration grid is arranged in a main flocculation tank body; a water discharging port is formed in the top end of one side of the main flocculation tank body, and a sediment discharging device is arranged at the bottom end of the main flocculation tank body. Acid sewage can be effectively treated, and the treatment efficiency of the acid sewage is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, and more specifically relates to an aerobic device applied to sewage treatment. Background technique [0002] Sewage treatment (wastewater treatment): The process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] In recent years, the discharge of urban domestic sewage has become the main pollution source of China's urban water. Urban domestic sewage treatment is the top priority of urban water conservation and urban water environment protection at present and in the future. This requires us to deal with domestic sewage facilities. Construction is...

Problems solved by technology

However, the current sewage treatment tanks have high production costs and poor treatment effects.

[0004] In some industrial processes, such as food, paper, steel and other chemical enterprises, a large amount of sewage is also discharged during the production process, and most of these sewage are organic wastewater. This organic sewage needs to be treated before it can be discharged into nature, otherwise it will be discharged directly. In the natural water body, the dissolved oxygen in the water will be consumed rapidly, resulting in the lack of oxygen in the water body and affecting the survival of fish and other aquatic animals. At the same time, the suspended solids in the sewage are easy to decompose under anaerobic conditions to produce odor and deteriorate the water quality.

In addition to organic wastewater, acidified sewage is also produced in some industrial processes. If the acidified sewage is directly discharged into rivers, lakes and seas, it will have a great impact on the ecological environment.
