The sugar pressing waste liquid refers to the residue-less waste liquid obtained after the sugar mill waste water is filtrated; besides, wine brewing waste liquid and alcohol waste liquid can replace the sugar pressing waste liquid in the same proportion.
In order to improve the combustibility of the carbohydrates in the sugar pressing waste liquid, the sugar pressing waste liquid can be pre-treated by the following steps: implanting yeast and rhizopus in the 5%-20% weight percent of sugar pressing waste liquid (including residue), wherein the weight ratio between the yeast and the rhizopus is 1:3; fermenting for 10-20 hours under the room temperature i.e. 20-25 centigrade; and then filtrating the residue to obtain the sugar pressing waste liquid having a better effect.
The other raw materials in the invention can be purchased from the market, so that unnecessary details will not be given here anymore.
The novel environmentally-friendly high-energy alcohol-based industrial fuel of the invention burns in a combustion engine specially for an alcohol-based fuel, and can be used in almost all the industrial pyrolytical combustion fields.

The raw materials can be obtained from many sources, and are inexhaustible and low in cost. Each ton of the novel environmentally-friendly high-energy alcohol-based industrial fuel can replace one ton of diesel oil at the most, while the cost is less than ⅓ of the diesel oil, thus having extremely high economic benefit. The selected sugar pressing waste liquid is the substances abandoned by sugar mills after fermentation treatment. More than 3 million tons of sugar pressing waste liquid is discharged per year all over the country; and the enterprises have to spend large funds per year to treat the waste liquid because no good utilization method for the sugar pressing waste liquid exists in the prior art. The invention provides an excellent solution for utilizing the sugar pressing waste liquid which is actually a multi-win technical solution.
The novel environmentally-friendly high-energy alcohol-based industrial fuel of the invention can be applied in the pyrolytical combustion fields such as industrial boiler, kiln and the like. The tests prove that the novel environmentally-friendly high-energy alcohol-based industrial fuel is thoroughly clean and environmentally-friendly, is superior to the strictest international industrial emission standard on environmental protection, and can reduce enterprise energy cost, improve enterprise production efficiency and yield, and comprehensively improve enterprise market competitiveness.
