Problems solved by technology

[0003] However, as far as the current traditional equipment for preparing activated sludge-based granular biochar is concerned, the process is cumbersome and the cost is high. The sludge cannot be fed intermittently, and it is easy to accumulate locally. At the same time, the deodorization effect is not good, and the inorganic matter cannot be quickly integrated. Separation and sludge pre-dehydration, the product has high impurity content, and at the same time reduces the dehydration efficiency, the overall application range is small, and the preparation efficiency is low

Abstract

The invention provides a process method and equipment for preparing activated sludge-based granular biochar based on a one-step method, and relates to the technical field of sludge recycling. A separating and discharging component is mounted on the feeding device; the feeding device is fixedly connected with a reciprocating driving part; a scattering device is mounted on the feeding device; the bottom of the feeding device is fixedly connected with a deodorization inorganic separation part; a dehydration device is mounted at the bottom of the deodorization inorganic separation part; a diversion mounting part is fixedly connected to the side of the dewatering device; the flow guide mounting part is fixedly connected to the bottom of the deodorization inorganic separation part; a processing unit is mounted in the flow guide mounting part, inorganic substances in sludge can be effectively removed, meanwhile, the rapid dehydration performance is achieved, discharging is uniform, the deodorization effect is better, and the problems that existing preparation equipment is poor in deodorization effect, inorganic substance separation and sludge pre-dehydration effects cannot be rapidly integrated, consequently, the dehydration efficiency is reduced, and the sludge pre-dehydration effect is poor are solved. And the overall application range is small. The stable and high-efficiency preparation of the activated sludge-based granular biochar is realized.

Description

Technical field [0001] The present invention relates to the field of sludge resource technology, and more particularly to a process method and apparatus for preparing active sludge particles biocarbon based on one-step method. Background technique [0002] For sludge disposal, traditional methods are sludge films, sludge agricultural and sludge incineration. Sludge will cause a certain environmental problem. In order to meet the three principles of "harmless", "reduction", "reduction", "resource" of solid waste treatment, and construct a environmentally friendly society, and sludge resource is the final way out of sludge disposal. The hotspot of sludge resource use the latest research is that the sludge harmless biocarbon preparation technology can solve the adverse effects of sludge on the environment, or solve the problem of sludge, and can become treasure. More in accordance with the ecological sustainable development strategy. At the same time, the biocarbon of active sludge ...
