Water Quality and Pollution Assessment

Abstract This paper uses a single-factor index evaluation method to evaluate the water quality of the Cotai Ecological Reserve in Macau. Water quality evaluation is a necessary way to rationally renovate the water environment. In this paper, the average dissolved oxygen, average total nitrogen, average total phosphorus and BOD5 in the water environment of the ecological protection zone are used as the evaluation indicators of water quality. The analysis results show that the average dissolved oxygen index can maintain the requirements of water function zoning throughout the year. The average total nitrogen and BOD5 index exceeded the standard seriously. Therefore, the water quality index of the ecological zone needs to be improved.
