Description
Technical Field
The invention belongs to the technical field of garbage and sewage treatment, and particularly relates to a sewage and garbage global treatment recycling method, a sewage and garbage global treatment recycling device and a sewage and garbage global treatment recycling control method.
Background
The garbage is solid waste generated in daily life and production of human beings, has large discharge amount, complex and various components, pollution, resource and socialization, needs harmless, resource, reduction and socialization treatment, and can pollute the environment, influence the environmental sanitation, waste resources, destroy the safety of production and life and destroy the social harmony if the garbage cannot be properly treated. The garbage disposal is to rapidly remove the garbage, perform harmless treatment and finally reasonably utilize the garbage. The garbage disposal method widely applied at present is sanitary landfill, high-temperature composting and incineration, and the purpose of garbage disposal is harmlessness, resource utilization and reduction.
The garbage comprises domestic garbage, kitchen garbage, farmland garbage, garden garbage and other garbage, wherein the quantity of the domestic garbage is large, the existing garbage is treated, and the widely adopted mode is landfill or incineration. However, both landfill and incineration generate great damage to the natural environment, so that new changes are needed to treat the garbage, and a few enterprises are also dedicated to research on harmless treatment methods of the household garbage, wherein the treatment method of crushing, screening and drying is an effective treatment idea at present. Because the domestic garbage contains a large amount of melon peels, waste melons, fruits, vegetables, kitchen objects, coarse-particle inorganic matters and the like, the domestic garbage has high water content, is easy to breed bacteria, is putrefy and deteriorated, releases unpleasant gas, is smelly and is fumigated, and causes environmental pollution.
Meanwhile, the existing garbage treatment does not effectively utilize the residual value of the garbage, at present, the garbage is directly used as compost, but the untreated garbage is directly used as compost, and the garbage can be thoroughly decomposed after decades of treatment, so that the environment can be polluted, the safety of underground water is seriously threatened, and the nutrient supply of plants by the compost is not obvious.
On the basis, in order to better utilize the residual value of the garbage and achieve the purpose of changing waste into valuable, the conventional treatment mode is to ferment the garbage, including natural fermentation and high-temperature heating fermentation, wherein the natural fermentation time is long, generally more than half a year or even longer, the efficiency is extremely low, and a large amount of currently accumulated garbage cannot be treated in time; and a large amount of energy is consumed for high-temperature heating fermentation, particularly in alpine regions, the temperature energy loss is very fast, the high-temperature heating efficiency is low, the fermentation and the utilization of the garbage can be realized, but huge heat is consumed, and the waste cannot be paid back.
In addition, a large amount of liquid garbage is generated in the conventional garbage crushing, separating and fermenting processes, and the liquid garbage is usually treated independently, so that the liquid part needs to be introduced into other equipment or systems for treatment, the occupied area of the whole garbage treatment is huge, the equipment investment is more, the cost investment is large, and the cost investment is larger than the fermentation output value and cannot be paid; because the solid garbage and the liquid garbage need to be treated separately and are not mutually related, the existing garbage treatment efficiency is low and the treatment effect is poor.
Furthermore, current refuse treatment is divided into solid refuse treatment and sewage refuse treatment mostly, on this basis, needs to handle solid refuse and sewage refuse alone, so, need invest more manpowers and use the place, consume more resources.
