Basin/region water quality and quantity allocation II. Application

In order to test the feasibility of basin/regional water quantity and quality of joint configuration theory, taking the main stream of Huangshui River for example, this study analyzes the supply-demand balance and water consumption balance, simulates the change of water quality and identifies the water shortage type, constructs the water demand scheme and engineering scheme, and puts forward the recommended scheme. Taking the improved three-time balance as the guidance, the quantity of pollutants received in water function area in 2030 were simulated under the current pollution control level, the trend of water environment capacity was analyzed and the controlling pollution amount was allocated. The results show that with the scheme implementation, the proportion of water ecology for each water resources district will be above 60% with only 0.4% of water shortage induced by water pollution; the quantity of COD and ammonia nitrogen will be 4, 585.51t and 244.63 t into the main water functional areas in 2030 respectively, and the pollution amount will be controlled, meeting the water quality requirements for each water functional area. Basin/regional water quantity and quality joint configuration method is feasible.
