Abstract

The invention belongs to the technical field of sewage treatment, and provides a method for monitoring and removing poisonous substance selenium by using a microorganism electrochemical system. Basedon a microorganism electrochemical system and an external circuit system, the method comprises: 1) assembling a microorganism electrochemical system; 2) performing positive electrode carbon brush culture to form an electricity generation biofilm; and 3) performing continuous operation, adding 0-150 mg / L of selenium-containing waste water, carrying out stable operation, recording the voltage periodof selenium-containing waste water in a concentration gradient, and measuring the concentration, which is a characteristic concentration, of selenium-containing waste water outlet. Based on the microorganism electrochemical system, selenium pollution of water is monitored in real time on line, and poisonous substance selenium is removed. The method has multiple functions of electricity generation, monitoring, and poisonous substance removal, and is economic eco-friendly treatment technology.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a method for monitoring and removing endotoxic selenium of a certain concentration in water quality using a microbial electrochemical system inoculated with pure electrogenic bacteria. Background technique [0002] At present, the total annual sewage discharge in our country is relatively large. Serious water pollution poses a serious threat to the ecological environment and affects human production and life as well as future survival and development. Objective real-time evaluation of water pollution is an important part of early warning of water pollution. However, at present, selenium-containing water toxicity testing is mostly in the laboratory testing stage. The sample pretreatment is cumbersome, time-consuming, complicated to operate and expensive, which cannot meet the urgent needs of extensive early warning of water pollution. [0003] Traditional physical and chemi...
