Problems solved by technology

[0003] In the prior art, the sludge treatment methods cannot achieve a comprehensive balance in terms of resource utilization, environmental protection, cost saving, and feasibility. The methods of incineration, carbonization, and building materials have been realized in terms of resource utilization, environmental protection, and feasibility. A certain degree of balance has been achieved, but the technology is complicated, the operating cost is high, and the use is limited. It is suitable for

Embodiment Construction

[0033] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0034] Such as figure 1 Shown, a kind of treatment method that sludge is converted into biomass fuel, is characterized in that, comprises the following steps:

[0035] (1) Sludge pretreatment: The sludge is passed through the first filter device, the second filter device and the third filter device in order to screen out impurities in the sludge, and the filtered sludge is stored in the sludge storage tank ;

[0036] (2) Mechanical dehydration: After the sludge is mechanically dehydrated, the moisture content of the sludge with an original moisture content of more than 80% is reduced to 45%, and the discharged sewage is collected and flowed to the sewage tre...

Abstract

The invention relates to a treatment method for converting sewage into biomass fuels. The treatment method is characterized by comprising the following steps: (1) sewage pretreatment, (2) mechanical dewatering, (3) sewage drying, (4) sewage carbonization, and (5) cooling storage. The treatment method has the advantages of being high in filtering precision, few in impurities, low in moisture content, high in finished product quality, high in efficiency, and capable of realizing maximized utilization of resources and recycle utilization of an environment.

Description

technical field [0001] The invention relates to a treatment method, in particular to a treatment method for converting sludge into biomass fuel. Background technique [0002] In recent years, with the deepening of the sustainable development strategy, people have paid more and more attention to the transformation and utilization of sludge. Practical methods such as incineration, carbonization, composting, and building materials have been adopted; at the same time, the existing soil resources in our country are becoming increasingly worse due to environmental pollution, while the garden market and flower market are becoming increasingly hot. The demand for fertilizers and fertilizers for agricultural irrigation is becoming stronger. [0003] In the prior art, the sludge treatment methods cannot achieve a comprehensive balance in terms of resource utilization, environmental protection, cost saving, and feasibility. The methods of incineration, carbonization, and building mate...
