Description

Household garbage treatment device and method

Technical Field

The invention relates to the technical field of household garbage treatment, in particular to a household garbage treatment device and method.

Background

The resource utilization and reduction of the household garbage are called as a big trend of the environmental protection measures in the world nowadays. The domestic garbage is considered as the second largest pollution source next to domestic sewage in cities because of high pollution indexes. The method realizes the recycling of the household garbage, can effectively reduce the quantity of the urban household garbage, improves the urban sanitary environment and prevents diseases.

The domestic waste refers to food blanking residues in catering industries such as villages, communities, restaurants, hotels and the like and public dining halls such as families, enterprises and public institutions, schools and the like. And the wastes generated in the life process such as packaging bags, waste clothes, broken tableware, broken glass, bricks, plastic sheets, packaging boxes, wood chips and the like are generally classified into recoverable household garbage, kitchen garbage, harmful household garbage, other household garbage and the like.

The recyclable household garbage mainly comprises paper, plastics, glass, metal objects and the like, wherein the paper mainly comprises newspapers, periodicals, books, various wrapping papers, office papers, advertising papers, paper boxes and the like; the plastic mainly comprises various plastic bags, plastic packages, disposable plastic lunch boxes, tableware, toothbrushes, cups, mineral water bottles and the like; the glass mainly comprises various glass bottles, broken glass sheets, mirrors, bulbs, thermos bottles and the like; the metal objects mainly comprise pop cans, can boxes, toothpaste skins and the like; the cloth mainly comprises waste clothes, tablecloth, face washing towels, schoolbag, shoes and the like.

The kitchen garbage comprises food wastes such as leftovers, bones, roots, leaves and the like.

Harmful household waste refers to household waste that may pose a hazard or potential hazard to the environment without proper disposal. Such as fluorescent lamps, dry batteries, various chemical batteries, and the like, which contain harmful substances.

The other domestic garbage comprises wastes which are difficult to recycle, such as brick and tile ceramics, muck, waste paper in a toilet and the like except the domestic garbage, and the pollution to underground water, surface water, soil and air can be effectively reduced by adopting landfill.

The domestic waste has the following characteristics.

1. High organic content: it is rich in starch, protein, meat, oil, etc.

2. High water content: as the residual material of catering, the water content of the swill is about 70 percent.

3. High oil content and salt content: due to the dietary habits of China, compared with the food domestic garbage of foreign countries, the food domestic garbage (including hogwash) of China has high oil content and salt content besides high yield.

4. The hazard is large: the domestic garbage is easy to deteriorate, rot, decompose organic matters, breed mosquitoes and flies, spread diseases, generate a large amount of toxins, emit malodorous gases and pollute water and the atmosphere.

5. The resource property is strong: compared with other household garbage, the household garbage has the characteristics of high water content, organic matter content, salt content, grease content, rich nutrient elements and the like, and has great recycling value. The recycled plastic, waste clothes, packing boxes, wood chips and the like can be used as high-fuel-value fuel for household garbage incineration power generation. The recycled bricks, cullet, broken tableware and the like can be used as the domestic garbage filler.

At present, domestic garbage classified collection is carried out in China, and most domestic garbage is mixed after being transported to a domestic garbage transfer station, not to say that domestic garbage in China has not formed a classified storage habit. The current domestic waste classification in China basically adopts the technical processes that: the domestic garbage is conveyed to a manual sorting conveyor before screening by a plate chain type quantitative conveyor, is primarily screened and then is subjected to drum-type sorting, and finally is conveyed to an oversize material conveyor. The defects of the process are obvious, the manual sorting environment is severe, harmless treatment is not carried out, and direct resource utilization cannot be realized.

At present, the domestic waste treatment equipment of community level is few, and degree of automation is low, the domestic waste treatment equipment of many community level scales is when handling, need sort out the debris in the domestic waste, extravagant a large amount of manpower and materials, and a lot of equipment in case the letter sorting is not thorough, sneak into debris glass cullet, bone, debris such as chopsticks, can lead to the equipment card machine, need carefully clear up the back, the ability is worked once more, even person very, just can normally work once more after probably needing professional maintenance, such treatment facility, low efficiency.

The current community and household garbage resource treatment equipment is in a blank state.
