At the same time, it must be focus on the technological transformation and pollution control of the six sectors of the food, petrochemical, metallurgy, building materials, textile, and nonferrous metallurgy.
During architectural design, it is important to encourage the adoption of a new structural system, new wall materials and renewable energy.
It should introduce the low-carbon concept from the full use of solar energy, the choice of thermal insulation building materials, the rational design of ventilation and lighting systems, the choice of energy-efficient heating and cooling systems, etc.
During architectural operation, it is important to advocate the construction of low-carbon decoration and selection of low-carbon decorative materials to avoid excessive decoration.
One is to use crop straw resources as feed, fertilizer or training materials.

Membrane materials with a predominance of the thermodynamic component of transport cope well with the selective transfer of VOCs.
These materials have gained their widespread use due to their high permeability and stability of transport characteristics over time.
Therefore, they find real industrial application as materials for separating membranes [6].
Each subsequent application brings the selectivity of the composite membrane closer to the selectivity of the membrane material.

Modeling of PVA Modified Non-woven for Submerged Membrane Bioreactor Treating Synthetic Wastewater ZHANG Chun Hua , DONG Yu Ying*, ZHANG Feng Jie Department of Environmental Engineering, Dalian Nationalities University, Dalian 116605, China, zhangchunhua@dlnu.edu.cn, dongy @dlnu.edu.cn, zhangfengjie@dlnu.edu.cn Keywords: submerged membrane bioreactor; membrane fouling; model Abstract.
The commercially used membrane materials include ceramics and both unmodified and surface modified polymeric materials, such as polyethylene, polypropylene and polysulfone [11].
However, the high cost of membrane materials limits its further applications.
Polypropylene (PP) non-woven fabric (NWF) materials are composed of random network of overlapping fibers.
It shows that the cake resistance is the key part in fouling resistance when the operation is stable, which consists with Lim’s study.

It has negative impact on exploitation of plant biomass for pulp production in paper industry and biodegradation of lignocellulosic materials [1, 2].
Modulation of the composition, size and magnetic properties of these materials permit their use in a variety of instruments and formats for biosensing.
MNPs, with their reduced size and ability to be transported in biological systems and reacting medium, is superior to traditional materials.
The combination of some novel materials with MNPs had well improved the kind of electrochemical sensor, most importantly, compared with common biosensor based on expensive metal electrodes, the proposed sensor exhibit similar sensitivity and reproducibility.
Further experiments are undertaken to improve the problem such as introducing materials with excellent conductivity as filler to improve the performance of the electrode and modifying the surface of the electrode for better distribution of nanoparticles, and so on.

The key to the establishment of a "resource recycling-based society" is the zero emission process.
However, recycling materials will produce an amount of scrap that cannot be recycled and will become waste.
A design that considers the intended usages and includes recycling should be incorporated into the materials development to reduce as much waste as possible.
The presence of iron in these intermetallic compounds is assumed to increases the density of the material.

Recently, electrochemical/chemical dealloying has been widely employed to fabricate various nanoporous materials.
In particular, exploratory studies on the NPC-supported MnO2 (MnO2/NPC) composites as new electrode materials of supercapacitor or electrochemical sensors in 0.5 M Na2SO4 solution are also investigated.
For exploring the new functional properties of NPC, the cyclic voltammograms (CVs) are performed to investigate the electrochemical performance of MnO2/NPC composites as a new type of electrode materials of supercapacitor.
For NPC serving as a working electrode or electrode substrate, it should be emphasized that the mechanical integrity of NPC is key requirement.
