Description

A kind of high-efficiency refuse total system

Technical field

The present invention relates to environmental technology field, particularly a kind of high-efficiency refuse total system utilizing the organic matter gone out refuse classification to carry out integrated treatment.

Background technology

Current China domestic waste annual just with 10% speed increase, and the municipal refuse implementing simply and easy treat only accounts for 2.3% of total amount, and current China rubbish over the years is stored up shared cultivated area and is about 500,000,000 square metres, and direct economic loss reaches 8,000,000,000 yuans.National urban has now developed into 660, and wherein existing 200 cities are absorbed among rubbish encirclement.With urban population 2.6 hundred million, produce 440 kilograms of rubbish for each person every year and calculate, producing quantity of refuse is 1.14 hundred million tons, and the city of 1,000,000 populations can be made to cover 1 meter.And also increasing progressively with the speed of 8-10% every year.China has become the country that rubbish burden is the heaviest in the world, municipal refuse innoxious, subtract appearanceization and recycling treatment is extremely urgent.

The collection method of rubbish domestic is at present mixing and receives, and the kitchen in rubbish is remaining and bath pin class amount of substance is higher; Moisture and putrescible matter higher; Packed lack of standardization; Form that raw refuse is almost " bag in bag " is thrown in and in bag, material composition complexity cannot be classified; So we are commonly referred to as " high humidity composting " it possess following characteristic in field of environmental engineering:

1, mixing receives complicated component, and bagged articles content is high;

2, moisture is large, average moisture 50%, and limit moisture is up to 70%;

3, kitchen is remaining, dregs class content is higher, is separated with dehydration difficulty larger;

4, easy corrupt content of material is higher, deals with improperly and causes serious secondary pollution.

As can be seen here, the core technology of domestic garbage as resource process is effective sorting and the deep dehydration process of rubbish.

The sorting classification of existing rubbish is mainly by screening and manual sorting, and by component of refuse and moisture effects, rotary screen is frequent plug-hole in real work, if moisture is comparatively large, balling-up of simply uniting, cannot realize the classification effect that it is good.

Existing the deep dehydration of rubbish is mainly adopted drop from the method that combines of fermenting, mainly there is following problem:

1, severe operational environment, secondary pollution is serious: its cycle of moisture is long, bad smell gas emissions is large, Landfill Leachate Production large, the high processing cost of COD, BOD content is large in percolate to adopt the method for draining and fermentation evaporation to remove;

2, by refuse moisture variable effect, the serviceability extremely unstable of tunning.
