Among all kinds of environmental pollution, wastewater pollution is the most common and the degree of pollution is relatively large. The wastewater discharged by enterprises will have a serious negative impact on domestic water resources and ultimately affect people's healthy development. In addition, corporate wastewater pollution will also affect our country's long-term sustainable development strategy. Therefore, this paper will conduct relevant research and analysis on the environmental analysis and treatment of enterprise sewage pollution discharge. The main purpose is to promote scientific and reasonable discharge of enterprise wastewater, which is particularly important for enterprise development and social and economic development.展开更多

At present, the society gives positive encouragement and advocacy to the sustainable development of the project, and takes energy conservation and emission reduction as a very important task at present. Environmental protection has also become the primary factor of project construction. Central heating has been gradually adopted by construction workers in the heat network, mainly because central heating can greatly reduce the cost of the project. But if there is a problem in a node in the heat network, it will lead to a large area of the heat network without heating phenomenon. Therefore, due to the complex pipe network, the quality danger of heating pipe network is easy to occur in the construction process. Strengthening the construction technology is an important basis to ensure the quality.展开更多
