Abstract
The invention relates to a method for preparing solid fuel by means of high-concentration organic waste liquid. The method comprises the following steps that 1, the waste liquid which contains aromatic hydrocarbon and carbon chains and does not contain a sulfur element or a nitrogen element or a halogen is selected, and physical impurities in the waste liquid are removed in a filtering mode; 2, the waste liquid obtained after the physical impurities are removed is concentrated through a gravitational separation method to enable the content of organic matter in the concentrated waste liquid to be higher than 45 percent, and then concentrated organic waste liquid is obtained; 3, under the water bath condition at the temperature of 65 DEG C-70 DEG C, 5 parts by weight of stearic acid and 1.5 parts by weight of sodium hydroxide are taken to be added into 93.5 parts by weight of the concentrated organic waste liquid, the mixture is stirred evenly to be subjected to a reaction for more than 2 hours, after the reaction is finished, the mixture is cooled to room temperature, and then the solid organic fuel is obtained. According to the method for preparing the solid fuel by means of the high-concentration organic waste liquid, the industrial organic waste liquid is taken as the production raw materials, the waste materials are utilized, the production technology is simple, the pollution discharge and pollution control cost of enterprises is greatly lowered, and the prepared solid fuel is easy to carry and transport.
Description
Technical field
The present invention relates to organic liquid waste reutilization technology field, be specifically related to one and utilize high concentrated organic waste liquid to prepare solid-fuelled method.
Background technology
At present, high concentrated organic waste liquid mainly contains alcohol slops, bio-pharmaceuticals waste liquid, monosodium glutamate waste liquid etc.Waste liquid after distilled spirit is the high concentrated organic waste liquid of the bio-refractory that a kind of color is dark, Pollutant levels are high, COD8-12 ten thousand milligrams/L, BOD4-6 ten thousand milligrams/L.The waste liquid after extracting L-glutamic acid is handed over also to be a kind of high concentrated organic waste liquid Deng ionization, COD6-10 ten thousand milligrams/L, BOD3-5 ten thousand milligrams/L.This kind of high concentrated organic waste liquid all has the features such as COD and BOD is high, color and luster is dark, intractability is large.The treatment process of current high concentrated organic waste liquid has bio-oxidation pond method, anaerobic digestion, single-cell protein feed processed, indirect five effect evaporation concentration combustion method or composite fertilizers processed etc.Bio-oxidation pond method harnessing project floor space is large, and the treatment time is long, also can produce a large amount of foul gass and cause secondary environmental pollution to affect surrounding enviroment in treating processes; Anaerobic digestion one-time investment is large, and working cost is high, and the waste liquid after process just can reach emission standard after also needing process further; Single-cell protein feed processed also can only remove part pollutent, also will carry out liquid waste disposal in conjunction with other method; Five effect evaporation concentration combustion methods utilize the concentrated solution concentration of high concentrated organic waste liquid to be greater than 50% energy aptitude to burn, but because facility investment is large, the easy fouling of equipment, there is the difficult problems such as caking and coking, burning be insufficient in roasting kiln, equipment can not normally run, the problems such as the cycle of operation is short, and heat utilization ratio is not high.Someone proposed the single-action of heat smoke direct type or multiple-effect evaporation concentrates incineration technology in recent years, although this technology can solve the problem of thickening equipment fouling, but waste liquid being difficult to after single-action or multiple-effect evaporation concentrate reaches the requirement of incineration of liquor, namely in concentrated solution, the concentration of organic pollutant does not reach the requirement of 50%, generally can only reach about 40%, also there is heat utilization rate not high simultaneously, equipment is normally run, also need continuous postcombustion in the process of concentrating spent liquor burning just can reach the balance of energy, therefore running cost is also higher.
Summary of the invention
The object of this invention is to provide one utilizes high concentrated organic waste liquid to prepare solid-fuelled method, organic liquid waste can be recycled, and reduces the cost of pollutant discharge of enterprise pollution treatment.
The present invention for the taked technical scheme that solves the problem is: one utilizes high concentrated organic waste liquid to prepare solid-fuelled method, comprises the following steps:
(1), choose containing aromatic hydrocarbon and carbochain, and the waste liquid of not sulfur-bearing, nitrogen element and halogen, the physical impurity in waste liquid is removed by the mode of filtering;
(2), utilize the method for gravity separation to be concentrated by the waste liquid after taking-up physical impurity, by the COD value of potassium dichromate process monitoring waste liquid in concentration process, make the organic content after concentrating higher than 45%, obtain concentrated organic liquid waste, for subsequent use;
(3), under the water bath condition of 65-70 DEG C, get 5 parts of stearic acid to add in 93.5 parts of concentrated organic liquid wastes with 1.5 parts of sodium hydroxide according to parts by weight, stir, react more than 2 hours, after question response terminates, be cooled to room temperature, namely obtain solid combustible organic fuels.
As a kind of further optimization utilizing high concentrated organic waste liquid to prepare solid-fuelled method of the present invention: described step (3) is specially: under the water bath condition of 68 DEG C, 5 parts of stearic acid are got to add in 93.5 parts of concentrated organic liquid wastes with 1.5 parts of sodium hydroxide according to parts by weight, stir, react more than 2 hours, after question response terminates, be cooled to room temperature, namely obtain solid combustible organic fuels.
beneficial effect
Method of the present invention using industrial organic waste liquid as raw materials for production, utilization of waste material, production technique is simple, greatly reduce the blowdown pollution treatment cost of enterprise, and the solid fuel prepared easily carries and transports, using solid dye as production marketing, income can also be created for enterprise; In solid-fuelled process processed, do not produce harmful flue gas, avoid the secondary pollution in refuse reclamation process.
