| Abstract | The current environmental status of Tan Thuan industrial estate (IE) was reviewed after it has operated for seven years. The potential pollution in term of wastewater and air pollution was assessed with the focus on two air pollutants, S02 and suspended particulate matters, and two conventional water pollution parameters BOD and DO. A Streeter-Phelps or DO sag curve model was applied to determine the assimilative capacity (AC) of receiving water (Tacroi Canal). The result shows that the canal itself does not have enough self-purification capacity in case of lowest flow when BOD concentration in the effluent of the CWTP is higher than 50 mg/l. Industrial sources complex short-term model (ISCST2) was applied to estimate the dispersion of S02 and SPM concentration in the atmosphere. The AC of the atmosphere was determined as the total emission from the IE that results in the model output concentrations not exceeding the Vietnamese ambient air quality standard. The simulation model was run for four scenarios: no control emission, emission reduction by 75 percent for the main 12 polluting industries, fuel switching for the main 11 fuel-oil based industries and emission reduction by 75 percent for thermal power plant, and increase the stack height of the largest source (Hiep Phuoc power plant). An environmental management strategy for Tan Thuan IE was developed for wastewater and air pollution debating based on the AC of the atmosphere and the receiving water. Two kinds of economic tools charging scheme and tradable permits are suggested to applied. Overall replacement of traditional regulatory instrument by economic tools was not considered to be feasible and efficient at present. Therefore, a combination of the two approaches was proposed to be applied for the environmental management of the IE. |
