沱江氮污染物转化规律及污染容量
- NITROGENOUS POLLUTANTS TRANSFORMATION AND ASSIMULATION CAPACITY OF WATER FROM TUOJIANG RIVER
- 摘要:本文研究氮污染物在沱江水体中的转化规律及其主要的影响因素。通过实验室模拟试验和野外现场水团追踪试验求得氨氮在沱江水中的总消失速度常数kT、硝化速度常数k_N、温度校正系数θ以及氨氮的耗氧系数fn。在参数计算方法上较前人有所改进。建立了计算沱江氮污染容量的数学模式,并用该模式估算了沱江在不同流量和不同水温条件下所能容纳氮污染物的负荷量。
- Abstract:Nitrogenous pollutants transformation and temperature effect on the process in Tuojiang River were studied. The total decay rate constant, KT, and nitrification rate constant, KN of ammonia nitrogen, and temperature coefficient,θ were obtained through simulation experiment and field sample determination. A mathematical model with modified parameter estimation procedure for nitrogenous pollutants assimulation capacity was developed and used to calculate loading capacity of Tuojiang River for nitrogenous pollutants.
