Technical field
The present invention relates to field of energy source environment protection, and in particular at city Venous Industrial garden and construction method and solid waste Manage system and method.
Background technology
Urban Garbage Treatment in China lacks the Top Level Research, origin and corresponding mode classification for being generated for rubbish etc. Lack deep layer research, the practices such as the categorised collection of rubbish, processing disposition lack theoretical direction, thus cause garbage treatment efficiency with Effective levels are low.Due to lacking top layer theoretical direction, the technical research of Urban Garbage Treatment in China and application and go out foothold Hair loses count of, and basic goal is unknown, often relies on achievable, single " innoxious " treatment technology to dominate garbage disposal Process route has deviated from the directions and principles of " recycling " to a certain extent.Using city as the correlation theory of organic whole Research is inadequate, and garbage collection, disposition and the utilization of resources are divided there are serious industry, technology is divided, material segmentation, management, skill Art and engineering construction it is comprehensive not enough, be inclined in fragmentation.Generally lack the garbage classification for being suitble to Chinese characteristic, processing With the systems approach of the utilization of resources and best-of-breed technology route.
Invention content
The technology of the present invention solves the problems, such as：Overcome the deficiencies of the prior art and provide city Venous Industrial garden and structure side Method and solid waste and method using conservation culture as guidance, using city as organic whole and life entity, visually use The concept of " artery " and " vein " studies emphatically the purification of vein product and recycles mechanism, it is proposed that municipal refuse is concentrated Processing and utilization of resources new route form city Venous Industrial garden, prominent to embody globality, systematicness and practicability, realize city Green, cycle, the low carbon development of city's field of garbage disposal.
Wherein, city " artery " refers to natural resources is processed into product, and carry out consumption use to product in city, from And product is caused gradually to lose its function and becomes the industry process of waste.Simply it is summarized as：Resource --- product --- Process of consumption --- waste.City " vein " refers to waste is converted to regenerated resources in city, so that resource is again The industry process recycled, the reconstituted product of generation recycle participation " artery " process again.Simply it is summarized as：Waste --- Regeneration --- reconstituted product.City Venous Industrial garden refers to establish using Venous Industrial as leading eco industrial park, passes through vein Industry the linear economy pattern of traditional " resource --- product --- waste ", transform " resource --- production as much as possible The closed loop economic model of product --- regenerated resources " realizes that life and industrial refuse are turned waste into wealth, recycled.
City Venous Industrial garden proposed by the invention and construction method and solid waste and method, it is proposed that Yi Zhongcheng The system building mode in city Venous Industrial garden, core content include：" entirety, two paths, three concepts, four classes are followed Ring ".Wherein：
One entirety：City is regarded as an organic life entity, introduces the concept of artery and vein：City artery supply is all kinds of Raw material, product, energy etc. maintain city operations, and all kinds of wastes are generated during the production and consumption of city, are produced as vein Object by the purification and regeneration in Venous Industrial garden, is converted into new resource and the energy, injects city artery, then formed benign , healthy circulating system.
Two paths：It is analyzed from the top layer of humans-nature relationship, the two big origins that understanding solid waste generates, then in solid waste point In terms of class, disposition and resource regeneration, two different thinkings and technology path are formed, in this, as the basis in solid waste field Theoretical and guiding theory.
(1) the two big origins that solid waste generates：
First, agro-farming product waste.Derived from the product of natural, ecological, naturally dependent on sunlight, soil, air and water etc. Element using photosynthesis as Basic Mechanism, produces plant and derivative animal.As people is to the understanding and application level of these rules It is promoted, forms cultivation culture, efficiently output agro-farming product, and as the valuable source of city production and living.It is consequently formed Waste, origin are agro-farming products, and essence is ecological product, have Biomass Characteristics.
Second is that industrial products waste.Derived from the product of human industry, with the development of human sciences, industrial revolution process adds Soon, the excavation especially to fossil substance and the rapid promotion of Utilization ability, a large amount of fossils, chemical products come out, also as city The valuable source of city's production and living.The waste being consequently formed, origin are industrial products, and essence is artefact, have fossil class Non- ecosystem characterization.
(2) the two of solidification disposal of waste big route：
(a) classification of solid waste.The two big origins generated from solid waste then determine two macrotaxonomies of solid waste：Biomass class and Fossil class.
Biomass class includes：Garbage, kitchen garbage (swill), excrement, garden garbage, sewage plant sludge (are derived from excrement Just), expired food, dead animal etc..
Fossil class includes：The synthetic materials such as plastics, metal, glass, building concrete etc..
Problem is, in production and living, blended product emerges in an endless stream, and biomass class and fossil class combine together, hardly possible point It is difficult to resolve, the problem of this is current maximum, it is especially prominent in China.Wherein, the separating dry space from moist space technology that the present invention recommends will be two big Classification provides support.
(b) fixed-end forces.Theory based on two big origins, two macrotaxonomies produces two general goal line of reasoning lines.
First is " cycle " (Recycling).Mainly for biomass waste, should output energy resource, realize city Society's cycle of artery, vein, will more return origin, and close friend incorporates and is converted into ecological element, realizes the Natural Circulation of health. Anaerobic digestion techniques that the present invention recommends, methane purification technology, biological carbon soil utilize, and will provide support for circulation route.
Second is " using again " (Reuse).Mainly for fossil waste, regrown material is produced by re-manufacturing technology, is substituted Natural resources；By power generation by waste combustion or gasification production capacity, energy etc. is provided for city.It is presently believed that from fossil product Industrial waste can realize that limited society recycles by " using again ", but be difficult to friendly involvement or be converted into ecological element, it is impossible to Realize the Natural Circulation of real meaning, it is limited only to harmless discharge with natural relationship.
3rd, three concepts.With the idea of development of " green, cycle, low-carbon ", as the basic of city Venous Industrial garden structure Principle and requirement.
(1) it is green：It is energy saving, save land, less with chemical agent, reduce disposal of pollutants.
(2) it recycles：The first level, the harmony of man and nature is friendly, realizes the Natural Circulation of health；Second level, artery Efficient society's cycle is realized in vein organic connections；Third level, each enterprise in garden realize that the regenerated resources energy is shared, realize What is had complementary advantages recycles.
(3) low-carbon：In social cyclic process, carbon footprint is fully considered, reduce carbon emission；During Natural Circulation, Inhibit " carbon source ", cultivate " carbon remittance "；Found Venous Industrial garden carbon transaction methodology.
4th, four classes recycle.Both water cycle, energy circulation, nutrient recycling, carbon dioxide recycle.
(1) water recycles：All advanced treatment of wastewater in garden, reclaimed wastewater reuse substitute natural water source, make every effort to zero-emission.
(2) energy circulation：Using anaerobic digestion techniques, high grade methane is generated；It is efficiently burned using rubbish or gasification technology, Electric energy, thermal energy are provided for garden, as much as possible realizes energy balance.
(3) nutrient recycling：Using biomass waste is innoxious, stabilization technology, production biological carbon soil, by organic matter and The nutrients such as nitrogen, phosphorus, potassium return soil, for forestry or agricultural.
(4) carbon dioxide recycle：Using biological carbon soil, sandy bare land, salt-soda soil, mining area in repair, refuse landfill etc. The place afforested is difficult to, large area construction movement forest forms new carbon and converges.
