Abstract: The paper presents methodology for calculation of a spatial noise field in an urban area where the dominant noise source is road traffic passing over an overpass. The height of the overpass is variable, with one end in the foot, and with the other end at the top of a hill. On one side of the overpass is the hill, covered by vegetation. On the other side of the overpass is residential area with houses and multi-floor buildings. The noise map is obtained by SPM9613 software package, which is based on international standard ISO 9613.

Abstract: To advocate and promote environmental protection building decoration materials is the inevitable trend of the development of the times is the requirement of sustainable development, also is the construction of environmental protection, healthy living security. We introduced the environmental protection building decoration material advantages, classification and the current flow of Ding green building and decoration materials, and the environmental protection building material prospects into Ding exploratory prospects.

Abstract: South Hot Spring wastewater source heat pump technology was introduced, and the basic status and application situation of South Hot Spring wastewater were analyzed. The environmental pollution index of wastewater was detected. Besides, the energy efficiency ratio of wastewater source heat pump system in South Hot Spring was predicted. What's more, the payback period and environmental benefits of the system in theory were also calculated. It shows that the system's payback period is 7 years, while 351 tons of standard coal and 2.25 million kWh of electricity were saved.

Abstract: In ord to solve the hole collapse problem of mud shale in LiaoHe Oilfield,further research and improment of KCl drilling fluid was conducted.and promotion in mine house, two South Beach Sea and other regions, to prove that the strong anti-sloughing drilling fluid system capacity, accident low, Liaohe Oilfield meet the needs of sloughing shale.

Abstract: To reduce environmental pollution caused by waste drilling fluid , Liaohe Oilfield takes methods of sewage pit seepage control and waste drilling solidification disposal.Firstly,different impermeable material comparation has been taken , as a result , high-density polyethylene geomembrane (HDPE) was choosn as the impermeable material for sewage pit .which has features of good seepage control, good chemical stability, low price ,non-toxic and environment friendly.According to features of five different landforms in Liaohe Oilfield, corresponding seepage control programs are developed. impermeable material, implementation and measurement of sewage pit are unified and standardized.which prevent contamination of underground water caused by waste drilling fluid effectively. Finally, curing treatment of the waste drilling fluid is carried out ,forming a system engineering to meet the needs of environment protection and costs control.

Abstract: Abstract: In view of the situation of domestic iron and steel enterprises to energy-saving, consumption reduction, reducing emissions, to improve the environment and the development of circular economy, the gas of the top tank pressure relief from six blast furnaces in Baotou Group is recycled in the project which has been used in blast furnace of developed countries for more than twenty years. Although China is a big country of iron and steel, it has always belonged to the rough type development, and there has been no precedent application. This design solved the long-standing top charging even pressure diffused pollution of the atmosphere and the noise pollution to the surrounding environment, in addition to recovery the gas recycling.

Abstract: In the process of tourism development, the constant damage of tourism resources and ecological environment has aroused people’s wide concern. Low- carbon tourism is an important means for tourism industry to realize energy-saving and environment protection. Hengyang is a city rich in tourism resources, cultural heritage, and obvious traffic advantages. The comprehensive exploitation of Hengyang tourism resources exerts great significance on promoting transformation and upgrading of Hengyang tourism industry, speeding up the pace of constructing a powerful tourism city and further developing and expanding tourism in Hengyang .

Abstract: Saving energy and resources and protecting the environment is closely related to the sustainable development of our country and the people’s happiness, so we should take on actions conscientiously, change the economic development mode, lessen the energy consumption per Gross Domestic Production, at the same time, we should conduct energy saving and environment protection propaganda, wake up the people’s consciousness, lay down applicable laws and regulations and put them into effect, then the energy & resources saving and environment goal can be achieved.

Abstract: Through the data query method, we analyses the solar energy resources survey of the Panzhihua city, summarizes the thermal resources and the backward situation; Taking a small solar energy theme park as an example, we elaborated the use range and feasibility of the solar energy resources in the theme park. The results show that solar energy resources can not only protect the city environment but also promote the tourism development of Panzhihua city and the development of other related industries.

Abstract: With the development of printing technology, greater emphasis has been laid on environmentally friendly materials. Due to its printability and environmental friendliness, Water-based flexo ink is gradually gaining popularity at home and abroad, and has been widely applied in the field of printing. Different from other kinds of bills, scratch-type invoices have an additional scratch area on the surface, which highly covering performance is required for the ink applied. This paper emphatically analyzes and discusses: (a) flexo water-based covering ink and its application in scratch-type invoice covering region printing; (b) how to explore and evaluate new developed green inks. Compared with traditional inks, the water-based flexo ink is free of emissions of volatile organic compounds (VOC), and its popularization might have significant meanings for the environment protection and sustainable development.
