Biochar pulp prepared from garbage leachate serving as raw material and preparation process thereof

Abstract

The invention discloses a biochar pulp prepared from garbage leachate serving as a raw material and a preparation process thereof, and aims to provide the biochar pulp prepared from the garbage leachate serving as the raw material and the preparation process thereof, which have the advantages of the combination of energy saving and emission reduction and environmental management and low cost. Thepreparation process comprises the following steps of: mixing biochar, the garbage leachate, methanol, high-temperature sand and additives serving as raw materials; and crushing, homogenizing and filtering the mixed raw materials to prepare the biochar pulp. The biochar pulp is used for replacing fuel oil so as to effectively save energy and reduce fuel cost, plays a good part in managing urban environment, and fulfills the aims of promoting economic and environmental health and sustainable development. The biochar can be widely applied in the fields of substitute oil firing such as industrialboilers, power station boilers, industrial furnaces and the fields of urban environment management and the like.

Description

technical field [0001] The invention relates to a biochar slurry prepared from garbage leachate as a raw material and a preparation process thereof. Background technique [0002] Urban garbage pollution is another difficult problem of environmental problems. With the improvement of living standards, the amount of urban garbage and urban sewage discharge is increasing rapidly. The sewage discharged from the city is treated by the sewage treatment plant to produce a large amount of organic sludge and the garbage leachate produced by the landfill has become an urgent solution for the city. In the landfill leachate treatment process currently used, most of them adopt biological treatment, but because the COD in landfill leachate is generally around 10000-20000mg / l, and the concentration of suspended solids and ammonia nitrogen Also quite high. On the other hand, due to the low ratio of BOD / COD in landfill leachate and poor biodegradability, the efficiency of biological treatme...

Problems solved by technology

[0003] As we all know, energy has become one of the important constraints on economic and social development. In recent years, energy prices have changed rapidly, domestic coal, electricity, and oil supply contradictions have become increasingly serious, and the contradiction between economic development and resources and the environment has become increasingly acute. Energy conservation and emission reduction are of great significance. Difficult; resource scarcity and environmental degradation are major problems facing all countries in the world today, and various pollutions are increasingly damaging the earth's environment; human beings can only get rid of their dependence on natural fossil fuels as soon as possible and rationally develop and utilize renewable energy. In this context, biological Charcoal emerged as the times require. As one of the new clean energy sources, biochar has gradually been recognized and accepted by people. However, due to the imperfection of the existing technology, it is difficult to use biochar to replace traditional fuels, so it has not been widely used.
