Full-function closed cyclic treatment and utilization system for comprehensive waste

Abstract

The invention relates to a full-function closed cyclic treatment and utilization system for comprehensive waste, which comprises a household solid waste treatment subsystem, a sewer-discharged liquid sedimentary waste treatment subsystem, a slime processing subsystem, a comprehensive waste mixing and molding subsystem and a finished fertilizer adding subsystem. The invention is characterized in that the solid waste treatment subsystem, the discharged liquid sedimentary waste treatment subsystem, the slime processing subsystem, the finished fertilizer adding subsystem and the comprehensive waste mixing and molding subsystem are connected with each other; and remaining solid waste, liquid waste, auxiliary molding materials and fertilizer effect additives which are subjected to preceding sorting treatment are classified and output to the mixing and molding subsystem according to a physical processing classification method, and are mixed and molded into compound organic fertilizers for different purposes according to a certain size. The waste treatment method based on the system realizes the low-cost mixing due to physical adhesive properties of the liquid and solid waste and the slime, and realizes the rational utilization due to the value of the waste which can be used as the organic substance, thereby changing the waste into fertilizer, causing no secondary pollution and generating no redundancy. The invention can be conveniently implemented and used for production.

Description

(1) Technical field [0001] The patent of the present invention relates to a full-featured comprehensive garbage closed-cycle treatment and utilization system. The garbage treatment system has the comprehensive mixed treatment capacity of solid domestic garbage and liquid excretion of sewer garbage, and uses extra clay and finished fertilizers to sort out the garbage in the previous process. All the remaining garbage is pulverized and separated by physical means. After adding shaped clay, the fertilizer efficiency is enhanced and then converted into various forms of organic fertilizers. The patent of the invention has the advantages of convenient implementation, a wide range of garbage to be processed, and the investment scale is determined according to actual needs. It produces secondary pollution, realizes the recycling of all organic components of garbage, and has the characteristics of low processing cost. (two), background technology [0002] In essence, garbage is an in...

Problems solved by technology

[0009] Compared with the cost of initial investment, centralized garbage landfill is a method with low initial treatment cost, so it has been widely used, but this method does not follow the method of decentralized utilization of garbage. Collecting together, not only It is a waste of resources. In terms of degree and quantity, if the organic resources of landfill waste exceed the limits of degree and quantity, it will inevitably produce harmful side effects and have long-term harmful effects on the environment. To deal with this later impact, it will take a lot of investment This method is not the best way to deal with garbage. This method does not consider the comprehensive treatment of liquid garbage in the sewer system including human physiological excrement, and this part of liquid garbage accumulates over time. Nets, rivers, lakes have serious impact

[0010] 2. Garbage burning

[0018] The high investment is not conducive to large-scale cost requirements. The chemical treatment method of artificially modifying a substance has deviated from the direction of the usable value of garbage.
