How "junk Lanjin"
Wang Jing
Europeans from the United States developed the "gold rush" the sky, and that the times and with a simple rinse method of sediment from the Gold Rush. Ancient Chinese people have fossil Lanjin. Gold is because people have to exchange any of the intermediary goods, with all the gold there, until today, a lot of people eager to make money. In fact, the "gold" as a means of diversity, the scientists have been able to put the rubbish into gold, the Chinese Academy of Sciences Guangzhou energy there is a specialized refuse to change the date of the laboratory of new and renewable energy laboratory. But their methods more delicate, non-direct "point for the garbage," but refuse to be accepted into people, the needs of the community's shortage of resources or jujube power plants organic fertilizers, natural on the "money" a passer-by measureless. Variable waste electricity or organic fertilizer plant with a simple process that, in fact complex. First of all, you want to track garbage dump months collecting samples, the establishment of a database on the garbage classification. Because different areas have different types of rubbish, and some areas can be combustible materials, in some areas more than fresh, can only be determined after only classification is used garbage power plant or composting. If garbage generation, will have to deal with the burning of garbage, refuse incineration process in the heat into electricity. With the advantage of generating garbage is garbage dumps on the site, saving land resources, but the high technical requirements. Perhaps you have heard of, garbage incineration technology but if the Commissioner, the burning of carcinogenic dioxins will be released, secondary pollution. This is what scientists currently putting in a lot of effort to study the key issues. If composting garbage, the need for the establishment of the garbage dumps to the fermentation tank. The most senior generation and waste disposal methods is the use compost, and by the need to tackle the problems of science and technology is more. With garbage power plant equipment is the key to refuse incineration furnace, furnace decide the merits of the efficiency of waste incineration. After the garbage into the incinerator can be fully burning? How can the full combustion of refuse? , Etc., are all scientists need to answer clearly an important issue. That is the problem with these "garbage Lanjin" the basic principles. As the efforts of scientists, China's current "junk Lanjin" approach does not exist any big problem. Many brokers have to waste incineration technology from the laboratory transplantation in the market for processing MSW, and obtained good return. Such as Sichuan ring can be set up, for eating garbage circle surrounded Chengdu, in addition to suffering from both for the people, has built up its fortune can become rich. The company forecast that at present, China's implementation of the summary disposal of municipal solid waste accounts for only 2.3 per cent of the total, over the years the garbage heap stock has reached over 60 million tons. In 2001, China's urban life has reached 150 million tons of refuse. If low heat value of 800 kcal / kg, the equivalent calorific value of 700 kcal / kg of 17.14 million tons of standard coal if all the electricity used by 20% of the power generation efficiency, can be installed 3,180 MW power generating equipment, even if all domestic use garbage power plant construction equipment, the work will invest more than 65 billion yuan. "Central to the" unique intellectual property rights in China SHNB waste incineration boilers, the work overseas investment cost is only 24 per cent of imported equipment, "Central to the" exclusive property rights in China can realize its boiler power generation with garbage favorable to the unique competitive advantages. Its market prospects for a bright future. Excerpt from "Science Times"
