Identification of Water Environmental Risk in Industrial Parks

Water environmental risk identification (WERI) is a basic step for industrial parks in the regional water environmental risk (WER) management. It is an effective means to control risk damage in advance and help find out the regional hazard sources. It will be helpful for putting forward corresponding countermeasures to avoid water pollution accidents. Depending on the features of risk sources, control system, as well as regional risk receptors, and taking the enterprise and its surrounding area away from 1 kilometre as the evaluation unit, integrated evaluation index system (IEIS) was developed to identify the region WER. The analytic hierarchy process (AHP) was applied to determine the weight of each factor. Taixing Economic Development Zone (TEDZ) was taken as a case study for the application of the model. The results showed that 3.57%, 50% and 46.4% of the enterprises in TEDZ had high, medium and low risks, respectively. Countermeasures were provided for the decision-makers on the risk management.
