Garbage Classification Based on Fuzzy Mathematical Model

Research article of Global Journal of Energy and Environment Garbage Classification Based on Fuzzy Mathematical Model Yu Cao1*, Zhong Zheng2, Hairui Zhang1 1College of Science, China Three Gorges University, Yichang, 443002, China. 2College of Electrical Engineering & New Energy, China Three Gorges University, Yichang 443002, China. China is the world’s largest garbage importer, importing more than half of the global trade volume of garbage every year. By the end of 2019, “foreign garbage” was banned from entering the country, which led to the global attention to garbage treatment and classification. This paper studies the impact of foreign waste ban on China’s economy and environment and the problem of waste classification. By using the mechanism modeling method, a solid waste recycling and degradation model is established to analyze the impact of foreign waste ban on China’s economy and environment. Finally, it comes to the conclusion that the foreign waste ban slightly hinders the development of China’s economy and reduces waste to a certain extent Rubbish’s damage to our environment. In addition, the fuzzy mathematical model is established by using the fuzzy clustering analysis method to calculate the membership degree of the given garbage on all kinds of garbage and finally determine the types of garbage.

Emission control of pollutants in waste incineration power generation process

Review article of Global Journal of Energy and Environment Emission control of pollutants in waste incineration power generation process Sifang Kong 1,2, Jianlin Sun 1*, Xueqin Cheng 3 1School of Traffic & Environment, Shenzhen Institute of Information Technol-ogy, Shenzhen 518172, China. 2Shenzhen Key Laboratory of Circular Economy, Shenzhen Graduate School, Peking University, Shenzhen 518055, China. 3Shenzhen Shanshuile Environmental Technology Co., Ltd. The waste incineration power generation is not only an effective measure to deal with the urban domestic garbage, but also can realize the supplement of the urban electric energy resources. Because of the complexity and diversification of the municipal solid waste in our country, there are different and complex chemical reactions in the waste incineration process. The reaction itself has a direct hazard to the human body and the environment, especially the highly toxic dioxins, which is a key factor to hinder the development of the waste incineration power generation technology. In order to better improve the comprehensive benefit of the waste incineration power generation, this paper briefly analyzes the emission control of the pollutants in the waste incineration power generation process, and hopes to provide theoretical help to the relevant workers. Keywords: Waste Incineration; Power Stations; Pollutants; Emission Control ...

Essay on Sustainable Development of Ethiopia in Relation to Environmental Policy

Review article of Global Journal of Energy and Environment Essay on Sustainable Development of Ethiopia in Relation to Environmental Policy Kebede Lemu Bekelcha Department of Social Anthropology, Faculty of Social Sciences and Humanities, Bule Hora University In the developing countries like Ethiopia most of the environmental problems are caused by underdevelopment. Millions continue to live far below the minimum levels required for a decent human existence, deprived of adequate food and clothing, shelter and education, health direct their efforts to development, bearing in mind their priorities and the need to safeguard and improve the environment. For the same purpose, the industrialized countries should make efforts to reduce the gap themselves and the developing countries, environmental problems are generally related to industrialization and technological development (Yared, 2017:17). Keywords: sustainable Development, Environmental Policy ...

Power Planning

Research article of Global Journal of Energy and Environment Power Planning Peijun Jiang, Yiqian Gao, Ao Luo School of Electrical and New Energy, China Three Gorges University 43002, China This paper calculates the existing system reliability index and typical daily optimal load distribution, studies the optimization problem of the generator unit’s investment plan in the next ten years, and uses the minimum cost of the investment plan to establish a multi-objective planning model. Combined with the artificial bee colony algorithm. It also discusses the impact of a large number of renewable energy power generation access power systems on traditional power system planning, and proposes an experimental model to solve this problem. Based on the system enumeration method of fault enumeration, enumerate all possible states of the system at each moment, consider the total cost of the system, increase the load demand constraint on the basis, and obtain the probability of occurrence of low-order faults. LOLP, EENS and power outage fees. After the above analysis, after the fault order reaches 5th order, the LOLP of the system is negligible, so the power loss cost is considered to be 4th order. Using the minimum total cost as the objective function, the artificial bee colony algorithm is used to find the optimal solution. The uncertainty of the output of renewable energy in the power system greatly increases the risk of operation scheduling, does not guarantee the quality of power, and is currently economically poor. In view of the difficulties caused by the system components in solving nonlinear constrained power supply planning, an experimental model is also established.
