The present invention is owing to have employed above technical scheme, make it compared with prior art, the present invention is by the crystallization of a series of state-of-the-art technology develop rapidlys such as electronic technology, mechanics of communication, network technology, computer technology, automatic control technology, sensing technology and multimedia technology.Integrated garbage treatment method of the present invention and system are as the extension of intelligent system engineering and development, and it is by force comprehensive, and the professional domain related to is wider, is the consolidation and innovation of multidisciplinary technology.Concerning whole intelligent industry, the invention provides an example that can imitate and view and emulate, drive whole industry to highly integrated and intelligentized control method future development.
Adopt integrated garbage treatment method of the present invention and system, dumping, transfer and transport can be realized and carry out minimizing, resource and harmlessness disposing, and there is the features such as the comprehensive ability of garbage disposal is strong, garbage processing procedure supervision is comprehensive.
Detailed description of the invention
The construction of urban environmental hygiene cause infrastructure is very necessary, is also extremely important to the monitoring means improving environmental sanitation regulation and environmental protection.The infrastructure major project of integrated garbage treatment method of the present invention and system comprises: comprehensive garbage computation weigh system, between household garbage-compressing transit wagon, ight soil pretreatment workshop, ditch mud process workshop, Bulky Waste process workshop and changing food waste process workshop.Auxiliary conveyance system contains integrated management building, machine repair workshop and parking lot, and whole base takes up an area 50 mu, realizes dumping, transfer and transport and the minimizing carried out, resource and harmlessness disposing.
Below the infrastructure major project course of work and the flow process of integrated garbage treatment method of the present invention and system is introduced respectively:
1, household garbage-compressing transfer flow process:
Adopt domestic and international maturation process horizontal precommpression technological process process house refuse, be easy to compatible with existing standard container transport system, require at present to reach 500 tons/day, the extended capability of another reserved 200 tons/day.Logistics whereabouts: waste transportation is to garbage burning factory, and Leachate site enters regulating reservoir, is then transported to garbage burning factory leachate treatment station with tank car.
2, ight soil pretreatment workshop flow process:
Adopt the night soil-treatment technique of integrated solid-liquid separating equipment+flocculation sediment, to fecal pollution properties:
First carry out Separation of Solid and Liquid, integrated solid-liquid separating equipment realizes bulk noncombustibility sorting, the desanding of liquid manure, filtration, transmission, press dewatering function.Equipment totally-enclosed, fully automatic operation.
Then flocculation dewatering is carried out, the flocculation liquid prepared with liquid manure and the chemicals dosing plant of the conveying of mud screw pump is fully mixed into the retort of dewaterer with suitable ratio, drum-type spiral shell pressing dehydrator is flowed into after abundant flocculation, the Shaftless screw conveyor interlock that dewaterer is supporting with it, transports the slag that dewaterer is discharged.
Whole process preparation deodorizing treatment process, reduces the impact on environment to greatest extent.
Treatment scale 480m
3/ sky, design service life is 15 years.
