Main contents of "Building Energy Efficiency and Green Building Technology Integration"
   "Technology Integration" section of the building from the outdoor environment, energy conservation and energy use, water conservation and water use, materials and material use, indoor environmental quality and operations management 6, a total of 54 introduced building energy efficiency and The applicable technology of green building, some technologies are also introduced in combination with the case inside and outside the province. Welcome to the company's official website http://
   Regarding land-saving and outdoor environmental technologies, it is mainly required to build participants, and plans must be made in the early stage of the project to effectively utilize land resources under the premise of protecting and creating a good ecological environment. " Technology Integration " starts from practicality and introduces the comprehensive utilization of underground space, wind environment simulation technology, planting roofing technology and vertical greening technology of building exterior walls. The underground space utilization of Xinsheng Street in Shijiazhuang is an example of comprehensive utilization of underground space.
   About energy-saving and energy-using technologies, from building exterior insulation structure insulation technology and new energy-saving building systems, heating and air-conditioning refrigeration energy-saving technologies, renewable energy and new energy application technologies, urban and architectural green lighting energy-saving technologies And other energy-saving technologies introduced in five aspects, the main content: passive low-energy building technology, external wall insulation system, energy-saving doors and windows, external shading technology, water storage central air-conditioning technology, efficient integrated refrigeration station, exhaust heat recovery device, Various energy-saving technologies for pumps, fans and air-conditioning systems, solar photovoltaic technology, solar water heating systems, wind energy utilization technologies, intelligent lighting control systems, elevator energy feedback technology, grid harmonic control technology, distributed energy technology, etc.
   The passive low-energy building technology comes from Germany, which means that the heat loss in the external heat conduction process and the heat loss in the ventilation system are minimized through the construction and equipment technology under the premise of economical construction cost, and the solar energy is rationally utilized. Renewable energy sources such as geothermal energy and wind energy make the fossil energy not consumed ( or rarely consumed ) during operation , and the indoor environment meets the requirements of health and comfort. The Sino-German passive low-energy building technology demonstration project has been constructed in Hebei Province Building Technology R&D Center and Qinhuangdao “ in the water side †community and can be completed in 2013 . These two demonstration projects have pioneered the construction of passive low-energy office buildings and passive low-energy residential buildings in China, and their practical significance and historical significance are extremely important. At present, cities such as Tangshan are also developing passive low-energy buildings.
   With regard to water-saving and water resources utilization technologies, from the perspective of water conservation and water resources reuse, water balance technology, rainwater recycling technology, water reuse technology for sewage treatment, roof siphon rainwater drainage technology, and quality water supply are introduced. Technology, green irrigation water saving technology and water treatment monitoring system. Among them, water balance technology and green irrigation water-saving technology have been widely used in water supply systems in various cities.
The granular of Activated Carbon has a very good removal effect for less than the molecular weight below 480 extractable organic matters, and the removal efficiency is very low for macromolecular organic matters. This is mainly because the micro-porous structure of the activated carbon, too large organic molecules cannot into the pores of the internal activity carbon, only adsorption in activated carbon surface.
Comparing the adsorption effect of volatile carbon and organic compounds on activated carbon, we draw the conclusion:
Activated carbon has a big difference in adsorption for volatile organic compounds and extraction of organic compounds. Volatile organic compounds with the molecular weight increased, the adsorption effect is better; and the extraction of organic compounds reduce with molecular weight, the adsorption effect is better. This is mainly due to volatile organic compounds mainly polar is the small organic matter, and the extractable organic matter is the relatively large polarity of organic matter. Activated carbon itself can be seen as a non-polar adsorbent for water adsorption capacity of nonpolar substances, which is greater than the adsorption capacity of polar compounds. Moreover, the adsorbate molecule size and activated carbon in a certain proportion, which is the most conducive to the adsorption. For small polar molecules, the larger of the molecular weight, the more conducive to the adsorption.
