Abstract

The invention discloses a method for judging whether a chemical agent is put into production and used to affect the normal operation of a sewage anaerobic treatment system and an anaerobic reaction device used. The described anaerobic reaction device comprises an anaerobic reaction container, an oscillator, a gas collection container and a carrying container, the described anaerobic reaction container is placed on the oscillator, and the described gas collecting container and the carrying container are filled with liquid, and the gas collection container is placed in the carrying container with the opening facing downwards. At this time, the gas collection container is in a liquid-tight state, and the anaerobic reaction container and the gas collection container are communicated through pipelines. The determination method simulates the anaerobic environment, sets the same amount of anaerobic mud, sewage water quality and quantity in the anaerobic reaction device, and adds chemical agents (and blanks) equivalent to the production discharge concentration in the external environment to test, and passes the test. The CODcr removal rate and gas production were compared with the blank to determine whether the chemical agent is toxic to anaerobic bacteria.

Description

technical field [0001] The invention relates to a judging method and an anaerobic reaction device for determining whether chemical agents are put into production and use to affect the normal operation of a sewage anaerobic treatment system, and belongs to the field of sewage treatment. Background technique [0002] With the increasingly stringent national food quality requirements, food production enterprises will use various chemicals in the production process in order to meet the quality requirements, and a large part of the chemicals used will eventually be discharged into the sewage treatment system along with the sewage . The existing conventional sewage treatment system includes a regulating system, a sewage anaerobic treatment system and a sewage aerobic treatment system according to the process of sewage treatment. For these chemical agents that enter the sewage anaerobic treatment system with sewage, many of them will affect the activity of anaerobic bacteria in th...
