Analysis of water environment capacity and total quantity control prediction in Pingyang section of Aojiang River;

Combined with the project of Comprehensive Assessment for River Water Quality and Quantity, sampling interval, water quality simulation and prediction, water quality evaluation for different quantities, dynamic water environment capacity evaluation were reviewed.

Based on the generalization of river pollution sources, a method and a formula for calculation of water environment capacity are proposed.

It is found that pollution factor in under ground water around pollutant-holding water body is consistent with high content pollutant in surface pollutant-holding water body,that is to say,mainly because of organic pollution,the higher the concentration of pollutant in pollutant-holding water body,the higher the concentration of the same pollutant in underground water.

By calculating the ability for pollutant and studying pollutant total con- trol of Zhongshan proper section of the Qijiang River,the maximum pollutant discharge allowance was determined,and supplied science ba.

By calculating the ability for pollutant and studying pollutant total control of the Yulin proper section of the Nanliujiang river, the maximum pollutant discharge allowance was determined, and supplied science base for water environment quantitative management.

Application of S-P generalized model to analysis of water environmental capacity in Linyi water function area;

Study results show that it is feasible in theory and reliable on results to calculate water environmental capacity under unascertained information by unascertained mathematics.
