Current, substantial contribution, equipment all in the work of treatment of firmly grasping rubbish, have been dropped in countries in the world, and a lot of measures have been taked in the processing of rubbish.Main the have heat supply of burning, burning electricity generation, heat energy are made oil and are produced biogas etc., and these processing modes all need several ten million or the fund input of more than one hundred million units, and need a considerable amount of waste resources.For general middle samll cities and towns, the growing amount of rubbish is limited on the one hand, and fund is difficult to again bear on the other hand.The garbage disposal of samll cities and towns has faced many difficulties in making.China Patent No. 01113020.2 discloses the patent of invention that a kind of name is called " comprehensive city garbage treating method and system thereof ", adopts computer system processor in this method, and the cost of investment height is had relatively high expectations to administrative staff, comprehensive operation cost height.Samll cities and towns are subjected to capital effect in general, and this method is difficult to apply.

Summary of the invention

The objective of the invention is situation, a kind of little and effective waste disposal method of investing is provided, accomplish the effective utilization and the recovery of refuse at middle samll cities and towns.

To achieve these goals, technical solution of the present invention has adopted following steps:

A. rubbish storing;

B. rubbish oven dry is delivered to rubbish oven dry workshop with storehouse rubbish, sends into and dries processing in the dryer, and its thermal source adopts Electric heating or other mode of heatings such as fuel oil, fire coal;

C. screening separates, and by conveyer belt rubbish is slowly sent in the refuse sieving machine, by manually picking up foreign material such as plastic products, rubble tile block, glass, screening machine separation stack fertilizer and combustible;

D. the plastics of screening are put into the plastic processing workshop,, make plastics again by fire coal and electrical heating combination; The combustible that filters out is pulverized through pulverizer, mixes and other batching, and its proportioning is: rubbish combustible 40～60%, coal slime 20～35%, coal dust 10～20%, paper pulp 5～30% is after mixer mixes, be squeezed into coal briquette by briquetting press, or be pressed into other moulded coals, as honeycomb briquette with other mould.The composting that sifts out enters the compost fermentation pond after the composting pulverization process, mix leavening and fertile secondary material, ferments.

Fire coal that adopt in plastic processing of the present invention workshop and electrical heating combination are according to coal-fired heating earlier, and electrically heated again step is operated, and temperature is controlled at 150 ℃～180 ℃.But saves energy.

Described composting fermentation employing natural style pressure high temperature fermentation process more than 30 ℃, the cycle is 5-7 days.

The present invention has following characteristics: with mechanical grading, to rubbish classify, be convenient to the operation.Invest for a short time, can select for use arbitrarily for big samll cities and towns.Can turn waste into wealth effectively, create the wealth, national resources is saved in the creation of value.Do not have burning and contaminative and bury, do not produce secondary pollution, help environmental protection.

Description of drawings:

Fig. 1 is a method flow schematic diagram of the present invention.

The specific embodiment:

Embodiment 1:

Ci Yutuo town, Liaozhong County, Liaoning Province house refuse, wherein organic waste (comprising vegetables, root leaf, residue leftovers etc.) about 40%; Flammable organic matter (comprising foam, fatty plastics, vegetation leaf etc.) about 40%; Waste plastics bag, plastic products etc. about 5%; Glassware, brick and tile stone, cement products about 10%; Other are about 5% years old.Operation as follows:

1, with special-purpose vehicle rubbish is transported in the factory, is discharged in the rubbish storehouse and keeps in, percolate stream ditch is set in the storehouse, at any time percolate is flowed in the raffinate pond the about 1.5m of percolate generation every day ³
