Problems solved by technology

Although the cost of this method is low, due to the competitive relationship between the microorganisms in the activated sludge and the microorganisms in the sewage, the adaptability of the activated activated sludge to wastewater is poor, the cultivation period is long, the degradation ability is poor, the start-up is difficult, and the treatment efficiency is low. Low, complex operation and management, poor impact resistance

Abstract

The invention discloses a device and a treatment method for degrading organic wastewater by using microorganisms. The device includes a primary filter device, a reaction tank, an aeration device, a bacterial agent feeder, and a secondary filter device. The primary filter device and the secondary filter Both the device and the aeration device are connected with the reaction tank; the device of the present invention has strong practicability, simple and uncomplicated structure, low maintenance cost, short period for cultivating activated sludge, strong degradation ability of activated sludge, and high treatment efficiency; The invented treatment method can cultivate and domesticate high-efficiency microorganisms suitable for the characteristics of organic wastewater in a short period of time, greatly improving the activity and quantity of microorganisms in sewage treatment, and significantly improving the treatment effect.

Description

Technical field [0001] The invention is a water treatment field, which involves a device and processing method that uses microbial degradation organic wastewater. Background technique [0002] At present, organic pollution has replaced microbial pollution as the greatest water hazard.The water quality census found that the water quality of the water plant with water sources as the water source was unqualified, and the main reason was caused by the total amount of organic compounds exceeded the standard.At present, the domestication of microorganisms in the biological treatment of sewage treatment plants generally use natural activated sludge to cultivate domestication, and the pre -processing sewage into the active activated sludge reaction pool is directly treated.Although this method is low in cost, there is a competitive relationship between microorganisms in the active activity sludge and microorganisms in sewage in the sewage, which makes the active activated sludge's adapta...
