Description
Technical field
The present invention relates to field of garbage disposal, more particularly, it relates to the disposal system of a kind of percolate and method.
Background technology
It is world subject that municipal garbage " innoxious, minimizing, resource " processes utilization. The method that focuses on of current China town and country municipal garbage mainly has landfill, compost, burning. Landfill method floor space is big, and the minimizing degree of rubbish is low, need to do Anti-seeping technology, also to build methane recovery and percolate treatment plant, it is easy to subsoil water and surrounding air are polluted. Composting process is suitable for processing the rubbish many containing perishable organic matter, can realize the comprehensive utilization of part resource, but compost quality is wayward, and harmful components usually exceed standard. Waste incineration and generating electricity is very fast in China's development, but investment is big, operating cost is high, and the flying dust hazardness containing two English and heavy metal is big, difficult treatment, and cleaning system highly advanced and complicated despite the use of, but two English in flue gas are still difficult to control to and monitor.

Immersible pump is placed at the bottom of percolate collecting-tank, it is easy to corroded by percolate, and overhauls difficulty. Meanwhile, immersible pump instability of flow, easily bring impurity into, affect follow-up process program.
Usual municipal garbage percolate anaerobic digestion reaction process is: the pretreatment heating follow-up flow process of anaerobic reaction (such as nitrated/denilrification system).Percolate after heater via heating will be directed into anaerobic reactor, and the filtrate after anaerobic treatment flows directly into again follow-up flow process. When percolate organic pollution content is high, after anaerobic reaction of this system, in its effluent quality, content of organics is still difficult to be down to desirable level, and COD concentration is still higher. On the other hand, the percolate after heater heats is directly entered anaerobic reactor, can cause that in reactor, temperature is difficult to regulate, and fluctuation is bigger. The methane backeria played a crucial role in anaerobic reactor, temperature sensitive. In generally, the existence adaptive temperature of temperature methane backeria is 30-36 DEG C, exceedes this scope, or temperature fluctuation all can cause organic acid to accumulate in a large number relatively greatly, it is suppressed that the activity of anaerobe or cause their death.
