The paper aims to find out the best wastewater pollution control technology of high efficiency and low energy consumption in the Municipal wastewater treatment plants. The method of entropy weight TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) was used to build the estimate model for wastewater treatment technology of the plant. Choice of three municipal wastewater treatment plant processes is A/O, BIOLAK and A2/O. The close degree calculated by the entropy weight TOPSIS respectively is 0.4530, 0.4987 and 0.5176 in the treatment process suited for the municipal sewage treatment. The A2/O treatment process is the best, then is the A/O treatment and the worst is the BIOLAK treatment process. Entropy weight TOPSIS method, used in the assessment of the wastewater treatment technology is flexible, convenient, scientific and suitable for the assessment of sewage disposal technology.
