Embodiment 1

[0020] Embodiment 1: the specific steps of the resourceful treatment method of a kind of cassava alcohol sludge provided by the invention are as follows:

[0021] (1) Preparation of cassava alcohol sludge crude product. The dehydrated cassava alcohol sludge (water content 80wt%) taken from the sewage plant was placed in a constant temperature drying oven at 105° C. for 24 hours, ground and sieved to obtain a crude product of cassava alcohol sludge with a particle size of 20-50 mesh.

[0022] (2) Preparation of oxidized cassava alcohol sludge. Take by weighing the cassava alcoholic sludge thick product that 12g step (1) prepares, according to cassava alcoholic sludge thick product quality (gram) and the ratio of hydrogen peroxide solution volume (milliliter) be the ratio of 1:10.0, with 120ml hydrogen peroxide Solution (mass concentration is 30%) joins in the crude product of cassava alcohol sludge, oxidizes 10min under normal temperature, then with the crude product of cassav...

Abstract

The invention discloses a recycling method for cassava alcohol sludge, belonging to the technical field of recycling and comprehensive utilization of waste. According to the invention, cassava alcohol sludge is used for preparing cassava alcohol sludge-based active carbon; cassava alcohol sludge is used as a raw material and subjected to airing, drying, impregnation and oxidation with hydrogen peroxide, and drying successively, then zinc chloride is added for activation; high-temperature pyrolysis and carbonization via a chamber electric resistance furnace are carried out next; and then pickling with a hydrochloric acid solution, washing with distilled water and drying are successively carried out so as to obtain the finished cassava alcohol sludge-based active carbon. The cassava alcohol sludge-based active carbon BET prepared by using the method has a specific surface area of 678.1462 m<2> / g, an average pore size of 5.269 nm and rich micropores and mesopores. The method provided by the invention is small in pollution to environment, enables the utilization rate of the cassava alcohol sludge to be greatly increased, and mitigates environmental pollution caused by waste sludge.

Description

Technical field: [0001] The invention belongs to the technical field of comprehensive utilization of waste resources, and in particular relates to a resource treatment method of cassava alcohol sludge. Background technique: [0002] Sludge is the waste obtained after treatment in the sewage plant, which is mainly a heterogeneous body composed of colloids, bacteria, inorganic substances and organic substances. With the rapid development of my country's economy, a large amount of waste sludge is produced every year, which contains a large amount of harmful and toxic substances. If it is not handled properly, it will cause serious pollution to the ecological environment. Therefore, proper disposal of waste sludge has become a big environmental problem waiting to be solved. [0003] A large amount of sewage will be produced in the process of preparing cassava alcohol, and a large amount of dewatered sludge will be produced after treatment. As a kind of biomass sludge, cassava ...
