Abstract

The invention discloses a method for judging the degree of influences of chemical reagent production application on normal running of a sewage anaerobic treatment system. Testing is carried out through a specific anaerobic reaction device, the anaerobic reaction device comprises an anaerobic reaction container, an oscillator, a gas collecting container and a bearing container. The anaerobic reaction container is arranged on the oscillator. The gas collecting container and the bearing container are filled with liquid. The gas collecting container with an opening facing downwards is arranged in the bearing container. At the moment, the gas collecting container is in a liquid sealed state, the anaerobic reaction container is communicated with the gas collecting container through a pipeline. By means of the method, by simulating an anaerobic environment, a chemical reagent with concentration 1-10 times of the production emission concentration is added in the anaerobic reaction device at the same anaerobic mud amount, sewage water quality and water amount and external environment for testing, and the toxicity level of the chemical reagent to anaerobic bacteria in the sewage anaerobic treatment system is judged by comparing with a blank.

Description

technical field [0001] The invention relates to a method for judging the degree of influence of chemicals put into production and use on 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 the sewage anaerobic treatment system, thereb...
