    TECHNICAL FIELD
    [001] This invention relates to waste treatment equipment, and in particular, relates to a waste treatment method for the separation of solids and liquids and separation of organic and inorganic materials.
    [002] This invention also relates to a waste treatment apparatus to implement the method described above. FUNDAMENTALS OF THE TECHNIQUE
    [003] China is one of the countries that have the most serious domestic waste problems.
    [004] According to statistics, the production of urban household waste across the country was 115 million tons in the 1980s, and had been 143 million tons in the 1990s, the second production in the world, behind only from the United States.
    [005] Currently, the total amount of domestic waste piled up in recent years is up to 7 billion tons, and the amount of production increases at a rate of about 8.98% per year. The stored waste occupies a total area of up to 500 million square meters, which can be converted into around 500 km2 (750,000 mu) of arable land.
    [006] 70% of 600 large and medium cities across the country are surrounded by garbage, and urban development and the living conditions of surrounding residents are severely affected.
    [007] In China, waste treatment currently employs substantially conventional methods such as landfill, composting, incineration, etc. However, the conventional waste treatment techniques described above have well-known flaws. I. Waste Compost Treatment
    [008] Waste composting treatment is a biochemical process that decomposes organic components in waste using microorganisms. In the process of biological chemical reaction, through the interaction of organics, oxygen and bacteria, carbon dioxide, water and heat are emitted and, in the meantime, humus is generated.
    [009] Waste compost treatment has the following three disadvantages. 1. Debris, such as blocks, metal, glass, plastic, etc., cannot be decomposed by microorganisms, and these residues must be sorted for further treatment; 2. Garbage composting lasts a long period, occupies a large area of land, and has poor sanitary conditions near garbage composting fields; 3. The compound has low efficiency, high cost, difficult sell and little economic benefit.
    [0010] Waste composting treatment is indicated for organics capable of being decomposed by microorganisms and, therefore, it is a treatment technique indicated only for organic components in the waste, and not a final treatment technique for the entire waste .
    [0011] The waste composting technique has the notable disadvantage that indecomposable organic and inorganic materials cannot be treated and therefore have low degrees of volume reduction, quantity reduction, and safety. Therefore, garbage problems cannot be completely solved by compost treatment alone. In some places today, household waste is dumped in landfills for natural fermentation, then excavated after several years and sold as fertilizer after the indecomposable substances, such as plastic, have been sorted and separated. Truly, this fertilizer is dangerous for fruit trees, vegetables and crops because the indecomposable organic components (paper, plastic, fabric, rubber, etc.) in waste have a high content of heavy metals (Pb, Cd, Hg). If these substances are buried in the earth along with decomposable organic materials over a long term, in conjunction with the effect of rainwater, heavy metals will consequently permeate the compost of final organic materials, and foods produced using these composite fertilizers will certainly have excessively high contents of heavy metals, which is harmful to human health. II. Waste incineration treatment
    [0012] Garbage incineration is a process of placing garbage in an incineration furnace for combustion. Thermal energy is released after waste incineration, and flue gases and solid waste are generated in the meantime. Thermal energy needs to be recovered, flue gas needs to be cleaned, and the waste needs to be digested. These are indispensable processes in incineration treatment.
    [0013] Waste incineration treatment has the following disadvantages. 1. Toxic gases such as dioxin, mercury vapor in batteries, etc., are released during combustion of waste. The flue gases generated must be cleaned, but cleaning techniques are difficult and costly to operate. 2. The waste combustion process generates toxic and dangerous slag and dust, the amount of which is about 20% to 30% of the original amount. The toxic and hazardous slag and dust generated in the incineration must also be treated. 3. This is a resource-wasting treatment method, as resources capable of being recovered and reused in the trash are destroyed. 4. There are certain requirements for the low thermal value of waste in incineration treatment, and not all types of waste can be incinerated. 5. Investment for single use incineration equipment is high. III. landfill
    [0014] Landfill treatment of waste has the following disadvantages.
    [0015] Waste deposited in landfills is not the target of a purification treatment, and large amounts of bacteria and viruses still remain; latent dangers like biogas, heavy metal pollution are hidden; and the effluent liquid from the garbage will pollute groundwater resources for a long time. Therefore, this method has extremely high potential dangers and will cause endless problems for offspring. This method does not achieve a treatment for the reuse of waste, and it also occupies a large amount of land and bequeaths pollution sources to the descendants. Most importantly, the treatment capacity of each landfill field is limited and, after filling it, additional investment is still required for the construction of a new landfill field, further occupying the earth's resources. At present, landfill is prohibited by government order in several developed countries.
    [0016] Based on the general analysis, none of the waste treatment techniques used in China today is a method that can truly achieve the general objectives of waste reuse, safety and quantity reduction. SUMMARY OF THE INVENTION
