Disclosure of Invention

The main formula raw materials of the invention are analyzed as follows:

alcohol waste liquor the alcohol waste liquor is high-concentration organic waste water produced in the course of coarse distillation after fermentation of molasses raw material, and 13-15 tons of waste liquor are discharged every 1 ton of alcohol produced, and said waste liquor is the main pollution source of sugar refinery, and its main characteristics are: the pollution load is high, and the wastewater belongs to high-concentration organic acid wastewater; secondly, 10 to 13 percent of solid matters are contained in the molasses alcohol waste mash, wherein 70 percent of the solid matters are organic matters, and the rest 30 percent of the solid matters are ash; thirdly, the pH value of the molasses alcohol waste mash is 4-5, and the molasses alcohol waste mash contains sulfate radicals, chlorate radicals and organic acid and is corrosive to carbon steel equipment and pipelines; fourthly, the waste mash of molasses alcohol has deeper chroma, although it is nontoxic, the water body eutrophication can be caused when the waste mash is discharged into rivers, the environment is seriously polluted, and the waste of useful resources is caused.

At present, during the squeezing season, the alcohol waste liquid which needs to be discharged only in Yunnan province reaches 100 million tons, and during the positive dry season of the squeezing season, the pollution consequences are more serious, the continuous development of the health and economy of people is directly threatened, and meanwhile, the effective components in the waste mash are wasted. If the evaporation concentration method is used for treatment, the active ingredients after high-temperature treatment can be greatly lost, so that the active ingredients cannot be fully and reasonably utilized. How to effectively treat the pollution of the sugar refinery and fully utilize the resources and turn the waste into wealth is an important subject. The molasses alcohol waste mash is always a difficult environmental protection technology around the sugar industry in China, although research and effort have been made for more than ten years by related scientific research departments and sugar mills, so far, no method which has the advantages of low investment and low operating cost and can lead the treated waste mash to reach the standard and be discharged is available. At present, the forms of treating waste mash of alcohol adopted by sugar mills to form industrial scale mainly comprise: agricultural irrigation method, oxidation pond method, anaerobic biogas preparation method, evaporation concentration method, single cell feed preparation method, combustion method, water ash flushing method and the like. Because of the high concentration of waste liquid, complex composition, high treatment and operation cost, difficult sale of byproducts and other factors, the popularization and application of various treatment methods are limited, especially, the importance of environmental protection and the environmental protection and production of sugar mills and virtuous cycle are highly recognized from the strategy of sustainable development, and the coordinated development of social benefit, economic benefit and environmental benefit is achieved, so that a method for comprehensively utilizing alcohol waste mash and changing waste into valuable is sought.

The paper-making black liquor is the black liquor produced in the paper-making pulping process, and is a serious pollutant of water source, COD in the waste water discharged by paper-making industry accounts for more than 40% of total COD discharge amount of national industry, and the pollutant contained in the paper-making black liquor accounts for more than 90% of total discharge amount of paper-making industry, and its treatment difficulty is large, and it is serious to environment hazard, so that the treatment of the paper-making black liquor is the key of paper-making industry waste water treatment, and at present, a special equipment is required to be used as a method for recovering alkali in the black liquor to treat the black liquor, but the cost is large, the treatment effect is general, and.

The paper industry uses a considerable amount of water and is one of the important pollution sources causing environmental pollution. The papermaking white water contains fiber and stuffing, and the stuffing is rosin, aluminum sulfate, strength agent, talcum powder, polyacrylamide, etc. The direct discharge of the white water not only seriously pollutes water sources, but also causes a great deal of resource waste. At present, the domestic papermaking white water of a papermaking factory mostly uses a closed circulation recycling method, and the fine fiber and the filler are recycled in the whole large system, so that the defects exist, the product quality is seriously influenced, and the great burden is caused by water supply treatment, and the specific problems are as follows: white water contains various dissolved organic matters, inorganic matters and microorganisms, when a white water system of a paper machine is closed, along with the great reduction of fresh water amount entering the system and waste water amount discharged, harmful substances accumulated in the system are greatly increased, water quality is reduced, foam is generated, rotten pulp is generated, the pH value is out of control, glue application is difficult, precipitation and dirt are generated, meshes and blankets are blocked, viscosity is increased, water filtration is difficult, and the like, so that the wet part of the paper machine and the paper forming performance are influenced.

The jatropha seeds have high development value. The lacquer tree seed contains wax and fatty acid over 35%, and the extracted mixture is named as lacquer wax. The lacquer wax is an important chemical raw material for producing various fatty acids, fatty alkanol and the like, and has wide application field. The lacquer wax has a melting point of 50-55 deg.C, is solid at normal temperature, and is refined into Chinese wood wax. The wood wax is natural biological wax with excellent performance and is widely applied, and the global wood wax market is mainly supplied by Japan, namely the wood wax is called as Japanese wood wax, and the resource is very scarce. The lacquer wax also contains higher alkanol such as octacosanol and triacontanol, the former is a universally recognized anti-fatigue functional substance, and the latter is a natural plant growth regulator, has no side effect on human and livestock, has no pollution to the environment and has extremely high development value. The lacquer seed kernel contains almost no wax, the oil content is 12-15%, the extract is liquid at normal temperature, the content of unsaturated fatty acid (oleic acid and linoleic acid) is as high as 80%, and the lacquer seed kernel is a good vegetable oil. Therefore, the sumac seed kernel oil has a larger development space in China.
