摘要:Abstract: According to the characteristics of the wastewater in workshop of wet method, the feasibility of break point chlorination treating industrial wastewater containing ammonia nitrogen was studied. This paper focused on the content of ammonia nitrogen in wastewater; the effect of concentration of sodium hypochlorite solution on the treatment was studied, and at the same time, the dosage of sodium hypochlorite was investigated. The test results showed that: the process route of break point chlorination treatment of wastewater containing ammonia nitrogen is mature, having the effect on different concentrations of wastewater containing ammonia nitrogen. The optimum conditions are as follows: the influent concentration of ammonia nitrogen is less than 400 mg/L; the concentration of sodium hypochlorite is more than 8%, and then ton of water consumption of sodium hypochlorite is 40 - 60 L. Finally, aiming at the characteristics of wastewater, feasible treatment scheme is designed.
