◆ Reduce the cost of nitrogen and phosphorus nutrition

◆ Facilities occupying small area

◆ Storage energy and have the advantages of ecological and economical

◆ Simple operation

◆ No tail gas pollution

◆ Processing the problem of wastewater with surface active agents without foam

◆ You can unlike the non -biodegradable substance during the process of oxygen

◆ Reduce the toxicity of chloride organic matter

◆ The wastewater that can be treated with seasonal emissions

Basic principle

The EGSB reactor is composed of a waterfrier, a particle dirt layer, a three -phase separator and a sludge interface controller and a water seal. The entire reactor forms a cylindrical tower. According to the amount of water and water inlet, the diameter of the tower changes from 4-14 meters and heights from 15-20 meters.

The water inlet enters the cloth water device through the pump. The water flow flows evenly in the section of the reactor in the open hole of the cloth water. During the rise of the water flow, the organic matter in the water is constantly decomposed by anaerobic bacteria and converted into biogas. Therefore, there are a large number of tiny biogas gas foaming and rising with the water flow, forming the speed of the air flow, thereby increasing the granular dirt bed bed Layer disturbance and expansion.

As the water flow reaches the top of the reactor, the concentration of organic matter in the water is reduced to the minimum and the airflow speed reaches the maximum. That is, the concentration of organic matter in the reactor decreases from bottom to top, the speed of air flow increases from bottom to bottom, and the expansion of the granular mud bed layer increases from bottom to top. During the operation, the law of anaerobic reaction was made full use, that is, the two -step reaction law of acid and methane production, which maintained the characteristics of the two phase reactions of the reactor at the bottom of the reactor. Essence

The sludge interface controller adjusts the height of the separation layer interface in the three -phase separator through the principle of pressure difference to ensure the stability of the separation effect. When the sludge interface rises to a certain degree, the pressure is released by automatic control valve to return the excess sludge to the reaction to ensure the stability of the interface.
