Embodiment Construction

[0053] specific implementation plan

[0054] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. figure 1 The configuration of a carbonization treatment facility using the carbonization treatment method of the embodiment of the present invention is shown. The carbonization treatment equipment 1 comprises a first receiving hopper 10, a second receiving hopper 16, a mixer 14 and a carbonization furnace

[0055] 40. The carbonization treatment facility 1 produces carbonized materials by utilizing organic sludge generated during wastewater treatment. In the following embodiments, the case of using chaff as biomass is mentioned as an example, but the present invention can be applied to biomass other than chaff.

[0056] The first receiving hopper 10 is a storage tank for dewatered sludge. Dewatered sludge dewatered to a water content of about 70% to 85%, typically about 80%, is received in the first receiving hopp...

Abstract

The present invention relates to a carbonization treatment method, containing steps of: mixing a biomass and a dehydrated sludge to obtain a mixture having an apparent water content of from 30% to 70% and subjecting the mixture to a dry distillation treatment at 700-900 DEG C under an oxygen-free or low-oxygen condition to obtain a carbonized material.

Description

technical field [0001] The present invention relates to a carbonization treatment method of subjecting a mixture of biomass such as chaff and dewatered sludge to dry distillation treatment to obtain carbonized materials, and a carbonization treatment apparatus used in the carbonization treatment method. Background technique [0002] Wastewater containing organic substances discharged from households and the like is generally subjected to wastewater treatment in sewage treatment facilities. [0003] Organic sludge is generated during wastewater treatment, and the amount of organic sludge generated increases as the amount of treated wastewater increases. Then, the treatment and disposal of organic sludge becomes a big problem. [0004] When disposing of organic sludge, organic sludge contains about 99.9% water, so it cannot be disposed of as it is. Therefore, for weight reduction, various treatments such as concentration and dehydration treatment or further incineration or m...
