人类聚居区的水环境保护与水资源综合利用研究

In the light of the social cycle of water, this project covers the following four dimensions: 1) the extreme carrying capacity of water resources in urban areas and its.integrated utilization; 2) the supply and security system of safe drinking water in urban areas; 3) the highly efficient low-cost techniques of removing pollutants in wastewater and resuing wastewater as a resource; 4) the information system for the.monitoring, analysis, evaluation and control of the quality of water environment. As a result, we have been trying to establish a theory concerning the coordination of population, society, economy, water environment and water resources, as well as the.sustainable harmonious development model .（1）Extreme carrying capacity of water resources in urban areas and its integrated utilization In view of the theories in Resource Economics, Environment Economics, Water Resource Management and Population Growth, this project initiatively introduces the.conceptual model for the extreme carrying capacity of water resources, establishes a quantitative index system for water resource carrying capacity according as this conceptual model and a summary of the present index systems and their ways of construction, puts forward the evaluation model and the way of quantitative calculation of the extreme carrying capacity of water resources, and, solves the effectiveness and equity problem in gross environment capacity control with the new approaches derived from the quantitative index system and quantitative calculation of.the extreme carrying capacity of water environment in urban areas. On the basis of this study, a model is proposed for the water resource protection and optimal utilization of environment capacity.（2）Supply and security system of safe drinking water in urban areas This project compares the removal of algae in conventional water treatmentprocesses,pre-chlorination, pre-oxidation with potassium permanganate,pre-oxidation with perferrite; studies the principles and methods of the manufacturing of multi-functional perferrite compound, as well as its effects, mechanism and.equipment in removing the organics and ammonia nitrogen in micro-polluted water and in disinfection and sterilization. This research obtains the technical manufacturing principles of flocculating agent with gh-efficiency and multiple functions for the.water treatment; the techniques of highly-efficient adsorption and filtration by.continuous regeneration; and the technical principles for harmless disinfection..Through the research on the effects of four kinds of water (pure water, purified.water, cold boiled water, tap water) on the white mice’s growth, immunity,.inter-secretion, pathological tissues of the important organs, behaviors, this project.obtains the basic medical evidence of the effects of water quality on human health – a.basis for further study in water quality hygiene and nutriology..（ 3 ） Highly efficient low-cost techniques of removing pollutants in.wastewater and resuing wastewater as a resource.In the light of the adsorption and flocculation performance of sludge, the growth.patterns of the micro-organisms and the characteristics of their extracellular polymers,.systematic study of the organic degradation mechanism in Phase A of the AB process.develops the highly-efficient biological flocculation techniques for super-high loading.and the separation techniques for sedimentation in wastewater treating..Based on the thermodynamics, biothermodynamics and the principles of.chemical reactions, an analysis and research of the thermodynamic and kinetic.relations in microbial growth and substrate utilization in the biological treatment.process of wastewater, develops the energy-consumption index system and the.mathematical model for calculation of energy balance assessment in biological.treatment of wastewater, thus proposes the energy-saving means and technical.principles for municipal wastewater treatmen
