Description

Method for quickly and sanitarily sorting household garbage

Technical Field

A method for rapidly and sanitarily sorting domestic garbage relates to an operation system for the sanitary sorting economic production of the domestic garbage, and the technology for obtaining single sanitary material to meet the recycling requirement of the domestic garbage by the sanitary sorting of the domestic garbage through the production, conversion and cyclic utilization of biogas slurry and organic matter liquid; belongs to the technical field of environmental sanitation and solid-liquid waste resource utilization.

Background

Domestic garbage in China is characterized by complex components, large quantity and high water content. The total amount of urban domestic garbage reaches more than 1.93 hundred million tons per year in 2016, domestic garbage is produced by people every day by 1.0-1.2 kilograms per person per day, and the daily increase is carried out at a speed of 8% -10% every year, so that the phenomenon of 'garbage enclosing city' is generated, and the garbage treatment is quite attractive every day; the main mode of garbage disposal is as follows: the landfill or sanitary landfill, incineration and incineration power generation account for 95 percent of the total amount of municipal solid waste treatment, and as a result, the disposal cost is huge, the resources are wasted, no economic benefit is returned, and human health and environmental loss are brought.

At present, the known household garbage treatment is to put household garbage producers in classification or forcibly classify the household garbage, and is characterized in that a classification putting collection box is arranged at a garbage recovery point, namely, recyclable matters (waste paper, waste metal, waste plastic, glass and the like), kitchen garbage (leftovers, bones, vegetable leaves, tea roots and the like), non-recyclable matters (including other wastes except the two kinds of wastes), and hazardous matters (waste batteries, waste paint buckets and the like) are collected and treated remotely. In reality, the nature of the embodiment is not distinguished, and a correct conclusion can be obtained only by looking at the target household garbage collection box, so that three different garbage collection trucks are used for transportation in the classified collection, the cost is too high, the reality is not realized, and the result is a pile of garbage.

At present, some sorting facilities of domestic waste treatment are more advanced, and the complete set of technology has:

introduction of the product network "LJ Wuhua" technology mainly comprises a main method for sorting municipal domestic waste: the sorting of the municipal solid waste mainly adopts a method of air separation and heating sorting. The main classification after the separation of the municipal solid waste is as follows: organic matters, inorganic matters, ferromagnetic matters, plastics, non-recyclable combustible matters and sandy soil.

At present, the granted publication number CN 206240589U, publication date 2017.06.13 utility model patent of research and development: domestic waste sorter, characterized by: the domestic garbage is classified by adopting a physical classification method according to different material characteristics of the mixed garbage. Such as large, medium, small, shape, dry, wet, mass (weight) differences. The inertia force generated in the movement is different, and classification is carried out under the matching of the vibrating screen. "the result is: separating out light, dirty liquid and heavy substances, and treating putrefactive odor.

From the above embodiment and other domestic waste sorting methods and apparatuses, there is a common point: the method focuses on sorting plastics and magnetic materials, provides service for domestic garbage treatment enterprises, separates combustible materials and compostable materials, is convenient to burn and prepare fertilizer, and forms a secondary pollution and pollution circulating body. It is largely unknown that this cost is actually too large. This is confirmed by the following examples and data.

Wherein, incineration power generation: according to the recent social cost evaluation report of urban domestic waste incineration in Beijing City published by China university on the near day, the social cost of the whole process of Beijing domestic waste management, collection, transportation and landfill, is 2253 yuan/ton, wherein the social cost of collection, transportation and transportation is 1164 yuan/ton, the social cost of incineration disposal after entering an incineration plant is 1089 yuan/ton, and the health loss of dioxin carcinogenesis only reaches 764 yuan/ton. Improper subsidy policies stimulate enterprises to increase the amount of incineration, and lag behind, thus hindering the social civilization process of scientific treatment of the household garbage. According to the implementation scheme for three years of construction of the Beijing municipal solid waste treatment facility (2013-2015), eight incineration plants normally operate in 2018, and the annual incineration amount reaches 597.2 ten thousand tons, which accounts for 60% of the annual solid waste amount. At that time, the concentration of the Beijing dioxin will continue to be improved, and the health loss will reach 267.3 million yuan, namely 4476 yuan/ton. The social cost of the whole process of managing the household garbage of eleven incineration plants is as high as 373.2 hundred million yuan/year, namely 6250 yuan/ton, and the total cost is predicted to be 1.33 percent of that of Beijing CDP in 2018.

The domestic garbage is burnt to produce dioxin substances which belong to strong carcinogens, are extremely difficult to decompose under natural conditions after being generated, and can enter a human food chain through media such as soil, animals and plants and the like, so that the health of human is harmed; the urban domestic garbage incineration capacity in the urban area accounts for more than 50% of the total harmless (harmful equivalent standard generated by relative incineration) treatment capacity, namely, the urban domestic garbage incineration capacity accounts for more than 60% of the total harmless treatment capacity, namely, the urban domestic garbage incineration capacity accounts for more than 50% of the total harmless treatment capacity in 2020, namely, the urban domestic garbage incineration capacity is about 2.6 hundred million tons, namely, the urban domestic garbage incineration capacity of 1.3 hundred million tons only can not achieve the social cost, namely, the human health loss cost reaches 993.2 hundred million yuan, which is equivalent to 0.29% of the income which can be controlled by 2017, 74.45 yuan can be paid by one person in a year, and the number can averagely occupy, and if the urban domestic garbage incineration capacity falls on a few heads, the number is astronomical number.

Furthermore, the main emission of the domestic waste incineration is CO₂，CO₂Discharge is a form of household waste existence. CO 2₂The emission produces greenhouse effect, which directly causes frequent natural disasters. The domestic garbage incineration is resource material emission and waste, data show that the incineration power generation treatment processes of 6 urban domestic garbage researched by greenhouse gas emission characteristics of typical urban domestic garbage incineration treatment process of China, Yana and the like are greenhouse gas emission sources, and CO of each ton of primary garbage₂The discharge equivalent is 17-185 kg. In the process of burning domestic garbage to generate electricity, the most main greenhouse gas emission way is to burn fossil source carbon in garbage to emit CO₂And is 56-256 kg. CO per ton of raw refuse resulting from other processes (transport, auxiliary fuel and material manufacturing, sludge and percolate treatment, etc.)₂The emission equivalent is 80-102kg, which is 44-71% of the carbon emission of the waste fossil. One ton of domestic garbage is incinerated to generate electricity and the whole process of burning and discharging CO from the fossil source carbon₂The average value is 124kg, and if the year is 2020, the burning amount of the household garbage is 1.3 hundred million tons, and CO is realized₂The direct discharge amount is 0.1612 hundred million tons per year, which is equivalent to 2 million artificial forest ecosystems of million Seaham dams and absorbs the total amount of carbon dioxide annually.

Wherein, composting: the known domestic garbage has lower fertilizer components, is not like manure, and a large amount of nitrogen, phosphorus and potassium elements are required to be added in the fertilizer preparation process, and particularly, the heavy metals in the domestic garbage cannot be separated and selected by the domestic garbage solid material compost. The result of the composting technology from the equipment characteristics and the production process is that the production cost of the domestic garbage as the fertilizer is increased, the effective use value is lost, and the fertilizer value is also lost from the viewpoint that the soil is polluted by heavy metal.

According to the following steps: vol.15 No.6 Dec.1996, Ministry of agriculture and agriculture in China, and evaluation of municipal refuse compost quality and application thereof indicates that the quality of refuse composts produced in 2 mechanized refuse disposal sites in Wuhan City and old estuary City in Hubei province is determined and evaluated, and the fertility characteristics of the refuse composts and the influence of the fertility characteristics on the basic soil characteristics are researched by pot biological experiments and field sampling investigation methods. The results show that the total nitrogen and total phosphorus contents of all 7 tested garbage composts can not meet the requirements of national standards, the lead content of a few garbage composts is over-standard, and the garbage composts in Wuhan city are superior to those in the old estuary city. The garbage compost has certain fertilizer effect and can improve the nutrient content of soil under the condition of large-scale application, but the effective fertilizer supply time is short, and the soil desertification and pollution can be caused by long-term continuous application. The results of biological experiments, physicochemical inspection, quality conditions of the garbage compost, fertilizer characteristics of the garbage compost, and influence processes and research results of the garbage compost on soil physicochemical properties show that the garbage compost has certain fertilizer efficiency and can improve the soil fertility properties under the condition of large-scale application, but the hidden troubles of causing soil desertification and farmland pollution still exist after the garbage compost is continuously applied in large scale. On the other hand, although the application of the garbage compost on the acidic clay soil has certain soil improvement and fertility improvement effects, the application of a large amount of the garbage compost cannot replace chemical fertilizers, and a large amount of manpower and material resources are also needed, so that the agricultural production cost is inevitably increased, and the garbage compost seems to be irreparable. "especially the increase of the heavy metal content in the soil, people are reminded to pay attention to the possibility of soil pollution caused by the continuous application of a large amount of garbage compost. See the following table for details:

attached table: effect of application of waste compost on soil chemistry
