It contains the subjects of setting up an engineering research center, mainly developing leading products, giving priority to the development of a chemical industry by using Qinghai salt lake resources, actively popularizing results, stressing basic research and systematic management.展开更多

Solid waste is mainly from urban garbage and industrial waste. Sludge is from water treatment factories, paper mills, chemical factories, pharmaceutical factories, rivers and lakes. The waste and sludge are very harmful to water organisms, human health and drinking water, and directly affect the environment. Sludge and waste also occupy large areas of land. There are several methods to treat waste and sludge, such as burial, chemical treatment and incineration. Incineration is more effective than the展开更多

Green construction of civil engineering can play an important role in addressing the issue of reducing contamination. A common strategy used to study green construction of civil engineering to decrease contamination, decrease waste of energy, and increase utilization ratio of resource. Evidence suggests that green construction of civil engineering is among the most important factors for saving energy. Along with this growth in development of green construction, however there is increasing concern over sustainable development. While green construction of civil engineering presents a promising direction, some of the essential prerequisites can be cumbersome to acquire and can restrict decrease contamination. Therefore the primary goal of this article is through rational use of green construction technology, decrease contamination of water resource, enhance manipulation of electric energy consumption.展开更多
