In a conventional biotrickling filter system, small pieces of packing materials are filled in a cylindrical container and nutrient solution is sprayed over the bed.
Materials and methods Pilot-scale Rotating Drum Biotrickling Filter.
The latter are packed with small pieces of inert materials whose diameter ranges from few milimeters to few centimeters.
Hence, most bulk air passes through the interstitial space between the pieces and the inner part of the packing materials are not exposed to the gaseous flows.

Using these materials as OPC replacement binders may help reduce the expansion due to the ASR.
Experimental Program Materials and Mixture Proportion.
After that, mixing was stopped for 90 seconds to scrape down all materials collected on the sides of the bowl.
Finally, all materials were remixed at medium speed for additional 120 seconds.

Conclusion Through research on conservation planning of Huangbu Village, we had the keen understanding that village conservation planning is much more than simple space layout, but rather a comprehensive consideration of economy, industry and appropriate use of land; rebuilding urban village into modern residential community with good habitability, both rural and urban features, it requires in-depth investigation and research in the whole process, obtain first-hand materials, widely solicit opinions from villager representatives, and proactively seek collaboration from relevant departments.

Application of Computer Integrated Process System in the Pulp and Paper Industry Zhongjun Xiao School of Electrical and Information Engineering, Shaanxi University of Science & Technology, Xi’an Shaanxi 710021, China xiaodongjun08@sina.com Keywords: Pulp and paper, Computer integrated process system (CIPS), Process control system(PCS), SIMATIC PCS7.
The whole pulp and papermaking process flow can be described as that the wheat straw, cotton stalks, bulrush and other papermaking materials are prepared through the dry and wet process, and are digested in the digestion section mixing with digestion liquors (black liquor and white liquor) under high temperature, and produce coarse pulps through the digestion reaction, and through washing and filtering, the black liquors, residues and coarse fibers could be removed from the coarse pulps which could be turned into accepted pulps, and the accepted pulps are sent to the whitening section and turned into paper pulps through CEH three-section continual whitening, and the pulps from the washing, filtering and whitening workshop mix with other pulps according to certain proportion, and mix with fillings, gluing materials, coloring matters and other accretions, the mixed pulps could be formed, and the mixed pulps are put into the pulp pool, and diluted as the paper pulp with regulated concentration
The keystone of ERP of the papermaking corporation is the logistic management, and the raw materials, finished product quality and quality traceability should fulfill very high management requirements, and the system should follow from the finished goods to semi finished articles and to material suppliers, so the ERP system must effectively help the corporation to follow the quality responsibility, and offer strong quality management and following function, and allow the corporation to follow the quality from the finished goods to raw materials.
Conclusions At present, many problems such as numerous corporate quantity, small scale, deficient raw materials, large resource and energy consumption, lower production efficiency and serious pollution still exist in Chinese pulp and papermaking industry, and the key reason is that the technologies (including the industrial technology and the equipment automatization technology) are lagged.

Introduction Copper and copper alloy is widely used as structural materials with the characteristic of high strength, good toughness, easy processing and strong corrosion resistance.
The material model of H62 is the Eq. 2 to Eq. 6 and material properties are shown in table 2.
The re-crystallization process is completed and the grains present the tiny acicular distribution at point 2 where the materials is flowed upward and the inverted extrusion is conducted from this position, the deformation is acutely and the temperature is high.
(4) The microstructure prediction of the extruded part is conducted utilizing the established material models.
