                Anaerobic degradation of particulate materials and macromolecules is considered to 
follow a sequence of four steps: hydrolysis, acidogenesis, acetogenesis, and methanogenesis.
Recent studies have focused on destruction of floc structures and lysis of microbial cells to release biodegradable organic materials and render them more accessible to anaerobic digestion.
Materials and methods TWAS and seed sludge Raw TWAS was obtained from a WWTP in S city, Japan, and was stored at 4℃ in a feed tank.
It was also possible that MW irradiation creates a higher amount of intermediate molecular size organic materials (such as, colloids) between soluble (<0.45 μm) and particulate (>0.45 μm)[15].
The authors would like to thank the friends for their continual assistance in preparing and caring out this research in department of civil and environmental engineering, Tohoku University.

                Thus, formulating of the evaluation criteria, identifying their key role and the value functions for the purposes of frames optimization, cannot be done without taking into consideration the information collected during the initial-stages of the design and manufacturing process (Table 1).
Assessment of structural solution in the respect of economic worthiness requires the determination of production costs (material costs and overall production costs).
The value or worthiness of design variants of the frames is determined automatically without the participation of the design engineer.

Abstract: In the iron ore mining process, often encounter the fault fracture zone, the weak interlayer and the moisture content of the anomalous body is not a direct predictor of adverse geological formations, timely forecasts and governance of these geological disasters will affect the safety in production.
Therefore, prevention and control of water is for the iron ore mining safety of key geological factors.
But, magnetic prospecting limited to the ground of the application of the census of resource, really will be used in iron ore mine electromagnetic method, from the literature material or very lack.
Can quickly and effectively predict underground coal mine roadway of different space rich water abnormal body, the control of the coal and rock tunnel 120 m, face ahead of roof and floor, 100 m range of mine water gushing engineering problems, and also can evaluate the quality of the floor grouting effect and drilling the sealing quality.
If the magnet ore distribution uniformity, existing ahead rich water structure, still have the detection of conditions. 2 A test of mtem’ application in the iron mine 2.1 Engineering survey DongPing located in shandong province southwest direction, iron mine resources are rich, but relatively low grade.

Piglets are usually weaned at 8 weeks of age and the growing of the piglets is profit-key to the pig farms.
Material and methods Establish of the Hot-water insulation system To remove the hydrogen sulfide of the biogas, the purification system was set up in this study because of that the hydrogen sulfide of the biogas is more easily soluble in water than methane.
