Beneficial effect of the present invention:
1, can effectively contain the generation and the harm of dioxin
Primary composting is handled by the technology of the present invention, can effectively contain the generation and the harm (it is following that the dioxin discharge index can be controlled in 0.03ng/m3) of dioxin, can not only reach the discharge standard (standard of China's incinerator toxic emission dioxin is 1.0ng/ m3) of China, and can be better than most advanced world Japan and the discharge standard (0.10ng/m3 of European Union greatly,), this is the most outstanding beneficial effect of the present invention, also is that the present invention will make one of bright spot of major contribution for China and even world's environmental protection cause and human health.
Current, waste incineration and generating electricity technology both domestic and external, no matter be grate furnace, gas-controlled type boiler, CFBB etc., because the process of incineration treatment of garbage is an oxidation reaction, so, directly burn the primary composting that comprises plastics, unavoidably to produce a large amount of dioxin, though can control or reduce the discharging of dioxin by measures such as active carbon adsorption and bag-type dusts, if but poor management or misoperation is arranged slightly, the discharging that will exceed standard causes the serious consequence of dioxin contamination.Adopt the technology of the present invention disposal of refuse can effectively contain the generation and the harm of dioxin, need not just can reach or be better than most advanced world Japan and European Union's discharge standard, can reduce the risk of dioxin contamination greatly through active carbon adsorption and bag-type dust.Because dioxin is called as " the first under heaven poison ", and is extremely harmful to human health, thereby the direct burning electricity generation of primary composting often is subjected to the common people and resolutely opposes.
, innoxious thoroughly
Primary composting adopts the technology of the present invention to handle, can finish sterilization, sterilization, deodorizing, and can contain effectively that dioxin produces and harm, reach " no waste water, no waste residue " discharging, burn directly with primary composting that the dioxin generation is big, garbage loading embeading long-term pollution air is compared with underground water, innoxious more thorough.
, recycling rate height
Primary composting adopts the technology of the present invention to handle, and organic matter becomes fuel gas by the destructive distillation pyrolytic gasification and all effectively utilizes as new forms of energy; Inorganic matter and waste residue are as whole recyclings of interpolation raw material such as brickmaking, and its recycling rate has only about 50% to compare near 100% with recycling rates such as burning electricity generation, rubbish compostings, and its recycling rate improves greatly.
, minimizing is remarkable
Primary composting adopts the technology of the present invention to handle, and organic matter has become fuel gas and all collected utilization; Inorganic matter comprises that sieve sandy soil and lime-ash down all carries out recycling as the interpolation raw material of brickmaking etc., has reached " no waste water, no waste residue " to discharge, and the physical form of rubbish is all cleared up, and minimizing is near 100%.Can only decrement tens percent compare at most with burning etc. with present garbage loading embeading, minimizing is very remarkable.
