| With the development of society and economy and people's the continually improvement to environment requirement, water environment pressure is increasing, Total Quantity Control of Water Pollutants becomes an important research field in keeping the balance of environment and the sustainable development of the society. This paper presents the method of water pollution total control based on the environmental carrying capacity analysis ,the water pollution total control put forward to the total amount control plan suitable for the environmental protection with sustainable development of water environment was investigated through applying environmental science ,the statistics analysis,ect.As a useful attempt to total quantity control plan, it abounded with the theory and method of total amount control and provided science basis and decision support for the environmental managers. The conclusion of the research is as following:This paper carried on investigation towards pollution source of industrial enterprises and the towns and cities which lead to water pollution in Suzhou. Synthetic pollution index method is used to analyze and evaluate the water quality in the district. From quantitative evaluation results ,we may know that the major sources of the drinking water in Suzhou in 2006 could reach III class level, belong to a safety drinking water source; The water quality results of main lakes almost attained the goal of《Surface water functional district allocation in Jiangsu province》about the water area; the top five worst water quality in the main river is Zhang Jia Gang river, Jinghang Canal , the Eleven Yu harbors,Jishui harbor, Yan Tie pond, the one that better is Tai Pu river, Xu river.This paper has selected output value coefficient method and per-capita coefficient method which are relatively perfect to predict the emission of Chemical Oxygen Demand(COD) in Suzhou. The prediction on discharge coefficients of pollutant is a method combined with the grey model used to reveal the macroscopic development rule and the Markov Model used to seek the microscopic fluctuation,through the comparison of different emission prediction methods of water pollution in the total amount control plan. Use the gray model to predict the discharge coefficients of pollutant emission based on the data of Suzhou gross industrial output value and the discharge coefficients of pollutant emission from 1999 to 2006; Then apply Markov Model calculate the state transition matrix based on the results from last step, and make a prediction on deviation of the results form the gray model step, based on the prediction above, we gave some modification about the discharge coefficients of pollutant emission, increasing the reliability of the prediction result.This paper compares and analyses the measuring and calculating method in the water environmental capacity , combining present situation of water environment of Suzhou, selects environmental capacity definition method to calculate the capacity of COD in Suzhou, analyzes the rationality about the total control plan of chemical oxygen demand in Suzhou during eleventh Five-Year Plan ,analysis the accessibility of the total control plan of COD of Suzhou in the period of eleventh five years with Environmental Kuznets Curve.The Suzhou, in accordance with the government policies, make COD total amount reduction countermeasures from the reduction in engineering, the structure, the management, to fulfill the goal, so as to achieve the regional water environment protection target.Gini Coefficient is used in distribute total load of COD in the industrial and regional water pollutants in Suzhou ,Through calculating, we can find that the total load distribution in Suzhou regional water pollutants is reasonable, while, the total load distribution in industrial exceeded its rational range, the one on top of cone curve is the significant pollution source,also the main subject need to be restricted.Put forward that we should realize the maximization of economic benefit under the precondition of considering environment, resources, sector planning etc. realize the optimal adjustment of regional industrial structure and the synergistic goal of the optimal allocation about the resources, This paper builds up a sustainable development-oriented multi-objective optimal allocation model based on the total amount control on the COD capacity. This paper puts forward the concept of industrial water environment considering the constraint on optimal industrial structure in the model, calculates by the artificial neural network method.Practical applications in Suzhou indicate that the current distribution of water environmental capacity and water resources in Suzhou City is not scientific, nor conform to requirements of continual development. gross output value still has a large space of growth; water environmental capacity and water resources is redistributed after optimum design with this model, under conditions of constraint by the environment and the resources, gross output value has a tendency to increase, with the Coordination among the social economy, environment, resources。Therefore, combining the total amount control about the water pollutants and optimal adjustment about industrial structure is a more Scientific water Management Principle...
