Description
Technical Field
The utility model relates to a refuse treatment specifically relates to a rubbish storage hole filtration liquid collection device.
Background
With the increasing emphasis on environmental issues, energy conservation and environmental protection have become the subject of development in various countries, and have begun to provide industrial development opportunities for garbage disposal. The annual growth rate of garbage all over the world is 8.42 percent, and the growth rate of Chinese garbage reaches more than 10 percent. Worldwide, 4.9 million tons of garbage are produced each year, and only China produces nearly 1.5 million tons of municipal garbage each year. The accumulated quantity of domestic garbage in China reaches 70 hundred million tons.
It can be seen from the above that, in recent years, the situation of garbage disposal in China is very severe, and countries, enterprises and colleges make great progress in the development of new garbage disposal technology, but the garbage disposal technology still far cannot meet the requirements of huge markets, and particularly, in the aspect of garbage resource utilization, a great gap exists, and the technology and equipment are relatively lagged behind.
At present, the municipal refuse treatment modes in China mainly include composting, burning, sanitary landfill and the like, wherein the sanitary landfill and high-temperature composting technology are taken as main technologies, and the burning technology is advocated to develop in conditional cities, particularly in coastal economically developed areas. In recent years, fundamental research and application research work of waste incineration treatment in various cities is carried out, and a large number of NF series reverse combustion type, RF series pyrolysis type and HL series rotary small-sized waste combustion furnaces and a large number of hospital waste special-purpose incinerators are developed, and a large number of small and medium-sized simple urban incineration plants (stations) are built. In 1985, Shenzhen introduced the incineration complete technology and equipment of Mitsubishi corporation of Japan, built the first large (300t/d) modern integrated refuse incineration and power generation treatment plant in China, and laid a foundation for developing the domestic chemical work of municipal refuse incinerating devices in China.
The landfill is the final disposal mode of the garbage disposal in China at present, but due to the problems of the limitation of land resources, the influence of sanitary landfill on the environment and the like, the government needs to plan in advance, and the limited landfill capacity is applied to the waste after the stabilization, reduction and resource treatment of the garbage in the future.
With continuous and deep innovation and acceleration of urbanization process, the generation amount of urban garbage is increased year by year, and the components are more and more complex, so that the urban garbage is one of important factors for restricting the sustainable development of cities. The garbage itself contains a large amount of water, the landfill site is influenced by rainfall, surface runoff and other factors, and high-concentration garbage leachate (hereinafter referred to as leachate) with complex components and difficult degradation is formed after a biochemical process. The improper treatment of the leachate can cause secondary environmental pollution, and affect surface water, underground water, soil and the like. From the viewpoint of the generation mechanism of percolate, the sources are mainly as follows: precipitation, surface runoff, garbage moisture, moisture in the garbage covering material, moisture generated by the degradation of the garbage, moisture generated by the evaporation of the garbage, and the like.
According to the construction age of the landfill, the percolate can be roughly divided into a young percolate (less than 5 years) and an old percolate (more than 5 years). Wherein, the pH value of the water of the 'young' percolate is lower, and the contents of COD, BOD/COD ratio, heavy metal ion concentration and the like are higher; the pH value of the aged percolate is close to neutral, the ratios of COD, BOD and BOD/COD are lower, the concentration of ammonia nitrogen is higher, and the concentration of heavy metal ions begins to gradually decrease. In addition, the water quantity of the percolate is greatly changed, the water quality is influenced by factors such as garbage components, treatment scale, landfill process, age and the like, and the change range is also large.
Traditional leachate collection is that the manual work is directly gone to the landfill and is gathered, and this kind of collection mode not only receives the restriction of condition such as weather, also is difficult to realize the detection of leachate comprehensively simultaneously.
