The results of the investigation on sludge treatment systems over 400 municipal wastewater treatment plants in China show that only about 46 plants have sludge anaerobic digestion systems,most of which adopt thickening/mesophilic anaerobic digestion/dewatering process.

Study on pretreatment methods of measuring heavy metals for treating municipal sludge;

This article has mainly carried on the research about the processing which the microwave cooperated with different catalysts radiates on the methyl orange, the active colorful blue X-BR solution and the tail water of the municipal sewage plant.

It is hoped to provide basis for the future research and process design of odor control in other municipal sewage treatment plant.

Based on the effect of odor from the municipal sewage treatment plant on the surroundings, brings forward the concept of the acceptance of atmosphere quality.

Aimed at the problems rising from the municipal sewage treatment plant on the environment pollutions and the increasing residents complaints and the damage to worker health,analyses the forming mechanism of odor in sewage processing together with the close correlation of odor forming and sewage treatment process,from which brings forward the concept of odor process control.

Policy analysis for sludge treatment and disposal in municipal wastewater treatment plant;

Economical criterion of urban municipal wastewater treatment plant's layout optimization

Combining with sludge reduction,stabilization and change for harmlessness and usefulness,this paper summarized the main theory and techniques of sludge treatment and disposal in municipal wastewater treatment plant at present.

Comprehensive Evaluation Model of Urban Sewage Treatment Plant;

Research on energy optimizing mathematical model of urban sewage treatment plant

The selection of process programs is one of the most important steps in the construction of the urban sewage treatment plant, it plays a determinant role in the investment cost running cost effluent effect operation and management of the urban sewage treatment plant.
