Research on Establishing Monitoring Index System of Pollution Source in Puhe Basin

Scientific and reasonable monitoring indexes are the key to establish monitoring system. Based on the single index, it is essential to launch the optimization and selection of indicators. Take thermal power as the research object in demonstration area and adopt comprehensive evaluation and three parameters evaluation methods to select index, successfully construct system of monitoring indicators which include in COD, suspended solids, sulfur, oil, volatile phenol and ammonia nitrogen. It will provide theoretical basis and technical support to build intelligent water environment safety and pollution monitoring system.

Pollutant Discharge

With the increase of pollutants discharged into the water, it is difficult to control the water environment pollution via reducing part of pollutant discharge. Therefore, the control method of pollutant total amount of water quality based on fuzzy mathematics is proposed. Firstly, a control framework and process of the pollutant total amount was built. The total amount of pollutant discharged into this region was controlled within a certain amount to achieve the predetermined environmental objective. Then, water pollution of different regions was evaluated via water quality model based on the fuzzy mathematics in the region or key protection domain with severe pollution and a concentrated pollution source, which makes the comprehensive evaluation of the water quality pollution more scientific. Finally, the control of pollutant total amount was completed via the optimized combination of point source control and unit control of total amount. Experimental results show that the method is scientific, objective and reasonable during controlling the pollutant discharge. It controls the pollutant total amount excellently.

Selection Of

The problems of modern geological ecology associated with the study of pollution of sediments of water bodies by heavy metals are considered. The Volga River basin is quite heterogeneous, both in geomorphological and hydrological terms, and in thechnogenical development and usage. A fourrank taxonomy is presented for the selection of sites for monitoring, based on a combination of natural, landscape, climatic and thechnogenical factors. To the largest – the highest taxon – sites of the Ist category – bowls of reservoirs with the slopes and the urban zones, industrial and agricultural structures located within them are carried. Within these areas are allocated to smaller taxa, areas category IInd are the industrial and urban zones, areas category IIIrd are the small rivers without significant contamination and areas category IVth to conduct special observations. The examples of special observations in the study of the annual migration of heavy metals in the system «bottom sediments – water column» on the Ivankovo reservoir are highlighted. The investigations were carried out under the conditions of the standard flow rate for this reservoir and in the conditions of slow water exchange.
