Embodiment Construction

[0013] Firstly, the organic waste to be processed can be:

[0014] Sludge from municipal sewage treatment plants;

[0015] Vegetables, fruits, inedible meat, eggs, fish and other garbage and straw packaging directly produced by farmers' markets or sorted or classified from municipal solid waste;

[0016] "Swill" and leftovers from restaurants, canteens, etc.;

[0017] Green grass, fallen leaves, branches, etc. produced by landscaping;

[0018] Process method:

[0019] Put the mixed sludge into the strip treatment pool which is made of bricks and concrete, about 1.5 meters high, 5 meters wide and 10 to 100 meters long.

[0020] The process is: sludge → add more than 2% microbial agent → add 6-8% cellulose → add 7-10% shell powder → add more than 8% of the treated product → fully mix → put into the strip treatment tank → Stirring and venting (5-7 days, 4 times / day) → discharging (feeding ratio is weight percentage) → biofuel.

[0021] Microbial agent: specially provided, co...

Abstract

The invention relates to a microorganism fast drying technology method for sludge and treatment products, and the technology method is as follows: the sludge (treated materials) is sequentially added with microbial agents, fiber, shell powder and rice straws and the products after the treatment to be fully mixed, the obtained mixture is put into a strip-shaped treatment tank to be stirred, with air and materials to be discharged(the proportion of added materials is weight percentage), finally biological fuels (treatment products) are generated. The microorganism fast drying technology method for the sludge and the treatment products according to claim 1 are characterized in that: the generated treatment products can be used as the biological fuels by using the microorganism fast drying technology method for treating the sludge and organic garbage. The microorganism fast drying technology method for the sludge is used for treating the sludge and the similar organic garbage which are generated in a sewage treatment plant, thereby improving the treatment efficiency of the sludge, being beneficial to the environmental protection and allowing the treatment products to have new purpose.

Description

Technical field: [0001] The invention relates to a process method for treating sludge, in particular to a process method for treating sludge and similar organic wastes by rapid microbial drying. Background technique: [0002] In the past, the treatment methods for the sludge produced by the sewage treatment plant include: heating and drying method, lime residue method, composting method and so on. The first two methods require large capital investment, and the processing cost is relatively high. However, the composting fermentation method requires nearly 30 days of processing time, requires a larger floor space, and has lower efficiency. In terms of processing products, traditional drying processing methods produce processing products that are mainly used as organic fertilizers or as building materials. Invention content: [0003] In order to overcome the technical problems existing in the prior art, the present invention provides an aerobic microbial rapid drying proces...
