Chemical constant-temperature anaerobic degradation device capable of continuously sampling

Technical Field

The invention relates to the technical field of anaerobic degradation devices, in particular to a chemical constant-temperature anaerobic degradation device capable of continuously sampling.

Background

With the development of chemical industry, the yield of various chemicals is greatly increased, and new chemicals are also emerging. People can generate a large amount of chemical waste while fully utilizing chemicals, and toxic and harmful substances are not contained in the chemical waste. Due to uncontrolled random discharge and other ways of discharging chemicals, the environmental conditions are increasingly worsened and the environment is seriously polluted.

Anaerobic biodegradation is a process of converting organic substances into various organic acids, alcohols, CH4, H2S, CO2, NH3, H2, etc., and a small amount of cell substances using metabolic activities of anaerobic microorganisms under anaerobic conditions. It is a process of concerted metabolism of multiple populations of bacteria. In the process, the metabolic processes of different microorganisms are mutually influenced and restricted to form a complex ecosystem. And some chemicals which are toxic and harmful to the environment can effectively solve the pollution of the chemicals to the environment through biological anaerobic degradation. On the other hand, parameters related to anaerobic degradation half-life, reaction rate and the like and anaerobic degradation reaction are important parameters for measuring the stability of chemical substances in ecological environment, and have important significance for predicting the environment of chemicals. To accurately obtain these parameters, single factor tests in the laboratory need to be performed. The reaction conditions of each sampling point in the anaerobic degradation device are consistent, and the method is an important guarantee for accurately obtaining the parameters.

We find that the existing device has no controllable temperature when the anaerobic degradation device is actually used, and can carry out the anaerobic degradation device with a plurality of groups of continuous sampling experiments simultaneously, and we find that reagent needs to be added in the middle of the anaerobic degradation experiment process sometimes to develop the degradation tests of different influence factors, so that the reaction condition of the reaction device can be influenced in the adding process, and the accuracy and the reliability of reaction experiment data are further reduced.
