Abstract

The invention provides a micro-aerobic environment moving bed biological film reaction device and a method for utilizing the same to treat coal gas wastewater, and relates to a water treatment deviceand a method for utilizing the device to treat the coal gas wastewater. The micro-aerobic environment moving bed biological film reaction device solves the problems that the effect of an existing coalgas wastewater treatment device on removing the pollutants in the coal gas wastewater is poor, the hydraulic retention time is long, and the treatment fee is high. The micro-aerobic environment moving bed biological film reaction device comprises a pond body, two underground water impellers, two aeration heads, a sludge return pipe header pipe, an air pump, a settling pond, a water impeller fixing rod and a partition wall. The method comprises the steps that 1, the coal gas wastewater enters the pond body from a water inlet pipe and a water inlet through the gravity flow hydraulic dropping mode, and the underground water impellers are opened; 2, the air pump, a valve on an aeration branch pipe, a valve on a sludge return pipe branch pipe and an electromagnetic valve are opened; 3, a biological film filler is added; and 4, hydraulic retention is conducted. The method is suitable for treating the coal gas wastewater.

Description

technical field [0001] The invention relates to a water treatment device and a method for treating coal gas waste water by using the device. Background technique [0002] my country's petrochemical resource characteristics of "rich in coal, poor in oil, and lack of gas" determine that my country must develop a modern coal chemical industry. In response to the current situation of insufficient oil and natural gas resources and rapid growth in demand, coal-to-gas will quickly become one of the leading industries in the modern coal chemical industry to make up for the current situation of insufficient clean fuels. The country's advocacy of high-efficiency and clean energy, the need to develop alternative energy sources for oil, the need to make full use of inferior coal resources, and the requirements to reduce environmental pollution have brought a broad market to the development of the modern coal-to-gas industry. Therefore, in the coming decades of transition to clean new e...
