Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto. Accompanying drawing is a kind of preferred form of technological scheme technological process of the present invention, and the operating process and principle of each unit device are as follows.

[0024] Raw material pretreatment unit: high-fiber wastes such as straw and gardens are physically crushed into segments smaller than 2 cm in the straw crusher 1, and the crushed materials pass through the material pipeline 2 and enter the material inlet 4 from the aerobic bioreactor I 3 Load into reactor I 3, the volume of the reactor is 80 L, and stay for 24-168 hours. The material after aerobic treatment is transported to the beater 17 with a volume of not less than 10 L through the material transfer device 15, and is pulped under the action of the stirring paddle 16. The pulped material passes ...

Abstract

The invention discloses a low-emission solid organic waste treatment system realizing methane and active carbon production. The technical method of the low-emission solid organic waste treatment system realizing methane and active carbon production uses a waste crushing treatment system, an anaerobic digestion raw material pre-treatment and blending system, an anaerobic digestion reactor system, an anaerobic digestion residuum dehydrating system, an anaerobic digestion residuum carbonizing system, a carbonized gas collecting, heat-exchanging and purifying system, and a treatment water recycling system. The technical integration of the low-emission solid organic waste treatment system realizing methane and active carbon production is capable of finishing the optimal treatment of the biomass solid organic waste, and the final product is the clean energy methane and environment-friendly material active carbon. The partial required energy can be produced by the technical method, the energy recycling rate is high, and the treatment on the exhaust gas and effluent can be finished in the production link, the system is energy-saving and environment-friendly. By sufficiently considering the influence of various factors and the coherence among various links, the period of anaerobically treating the biomass organic solid waste can be obviously shortened, and the treatment efficiency of the organic solid waste can be sufficiently improved.

Description

technical field [0001] The invention relates to the field of organic waste disposal and resource utilization, in particular to a technology integration method and device for resource utilization of biomass organic solid waste. Background technique [0002] The safe disposal and recycling of solid organic waste has always been an important issue in the field of environmental protection. At present, the amount of organic solid waste represented by kitchen waste, residual sludge from sewage treatment, garden waste, agricultural waste straw, and poultry manure has increased significantly in recent years. These solid wastes rich in organic matter are usually disposed of by landfill, composting and incineration. Although the landfill technology is simple, it has the disadvantages of large area and easy to produce various malodorous gases and leachate. In particular, the leachate produced contains high concentrations of nitrogen, phosphorus and various heavy metal ions, which has ...
