Problems solved by technology

[0003] At present, the existing sewage treatment methods include biochemical method and incineration method. The biochemical method often adopts a simple filtration method. This method has a simple equipment structure, but the filtration effect is not obvious; there are also high-end reverse osmosis technologies, but need to apply pressure. The structure of the equipment is complicated and the practicability is not strong; the incineration method is easy to produce harmful gases to pollute the air, and it is also very difficult to deal with the sewage components in sewage structures

Abstract

The invention discloses a method for treating sewage by microorganism through activated sludge inoculated flora. The method comprises the following steps: preparing an adsorbent; preparing a microorganism nourishment; preparing a barrier; pretreating sewage; fixing the microorganism; and treating the sewage. According to the method, the microorganism is high in activity, high in adaptability, highin degrading capacity, fast to biologically degrade, high in treating efficiency, and high in quality of treated water.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a microbial sewage treatment method using activated sludge to inoculate flora. Background technique [0002] Sewage mainly includes domestic sewage and industrial wastewater. Among the water pollution caused by human production activities, the water pollution caused by industry is the most serious. For example, industrial wastewater contains many pollutants and complex components. It is not only difficult to purify in water, but also difficult to treat. Industrial wastewater is the most important cause of water pollution caused by industrial pollution. It accounts for the majority of pollutants emitted by industry. The pollutants contained in industrial wastewater vary widely depending on the type of factory. Even in the same factory, the quality and quantity of pollutants contained in them are different due to different production processes. In addition to the pol...
