Abstract: MBR technology has been widely used in northeast China's leachate treatment projection for its obvious technical advantages. However, the complex nature of the Northeast leachate as well as relatively more calculations design of MBR process, became the key to the success of the project. This article in view of the present our country MBR treatment process of domestic refuse landfill leachate treatment of some design problems and puts forward some personal views and suggestions,, for example the MBR process calculation method of reference.

Abstract: There’s a sufficient solar energy resource in our country, but the shortcomings of its discontinuity and instability makes it hard for a further development. The research on multiple applications of the solar collector and phase-change material cannot only reduce the building energy consumption, but also improves the thermal environment. This method can make the solar energy into a continuous, stable and available state which has a very important meaning to alleviate the increasingly serious energy status. This article mainly introduced two united systems of solar energy collector with phase change energy storage wall and phase change composite floor, theoretical basis and actual operation effect for these two systems are introduced summarily in the article.

Abstract: Bio-drying is an important method to reduce the excess sludge which use the inner biomass of sludge itself to generate heat for a water discharging has a broad prospects in sludge treatment. However, our research in this field is still very limited. In order to better mastering and promoting sludge bio-drying technology, this paper summarized the advantages of bio-drying, initially described the microbial mechanism of spontaneous heat generation and the heat and mass transfer phenomena in a bio-drying process, then build a macro heat conservation formula based on material conservation.
