Abstract

The invention discloses a method for detecting the influence of Cu2+ on an electron transfer system of an SBR technology. The influences of Cu2+ on the nitrogen and phosphorus removal effect and the activated sludge electron transfer system (ETS) are investigated, and it is shown through results that under the condition that COD, NH4+-N and PO43--P of inflow water are 1,000 mg / L, 40 mg / L and 20 mg / L respectively, the average value of the activity of the INT-ETS of an anaerobic zone, an aerobic zone and an anoxic zone is increased by 4.5 mg / (g.h) when the concentration of Cu2+ is 1.0 mg / L compared with that when Cu2+ is not included, and when the concentration of Cu2+ is 10.0 mg / L, the average value of the INT-ETS is reduced by 65.1 mg / (g.h). Thus, it can be known that the influence rules of heavy metal on the ETS and the removing effect of pollutants are identical, and thus activity of the ETS can effectively represent the biochemical reaction process.

Description

technical field [0001] The invention belongs to the field of waste water treatment, in particular to a method for detecting Cu 2+ The method of influence on electron transfer system of SBR process. Background technique [0002] With the rapid development of mineral mining and metallurgical industry, heavy metal pollution in water is serious. Studies have reported that heavy metal wastewater is treated by activated sludge method. Heavy metals affect microbial population structure, growth and reproduction, and activity. At the same time, heavy metals also affect the effect of sewage treatment. The research on the influence of heavy metals on the effect of sewage treatment mainly focuses on the types, concentrations, and valence states of heavy metals. Wang Qin and others found that the ability of heavy metals to biological denitrification is related to the type of metal ions. Cu 2+ , Zn 2+ 、Cr 6+ 、Cd 2+ When the concentration exceeds 0.5mg / L, 30mg / L, 0.5mg / L and 5mg / L, ...
