Technical field
The present invention relates to a kind of mainly by liquid and waste slag produced organic fertilizer and the production method of forming with the starter that becomes thoroughly decomposed thereof in sugar refinery, the technical field that belongs to liquid and waste slag produced comprehensive treating process and utilization, be specially adapted to the sugarcane be raw material sugar-refining industry comprehensive treating process molasses alcohol waste liquid, produce organic fertilizer towards buck and bagasse, filter mud etc.
Background technology
In the sugar industry production process, produce molasses alcohol waste liquid, the alcohol slops ash-flushing water of enormous amount inevitably, (abbreviating " towards buck " usually as) and waste pollutants such as filter mud, bagasse, only molasses alcohol waste liquid is as if not treated direct discharging, and its harm to environment is surprising.Have and report: a medium scale sugar refinery of producing 100000 tons of sucrose per year, the COD total amount of the molasses alcohol waste liquid of its discharging is equivalent to COD total amount in the sanitary sewage of medium-sized city discharging of one 500,000 population, this causes serious pollution to river and surrounding environment, very far-reaching to the eubiosis and water resource destruction, and the waste in improvement sugar refinery is a global problem.For a long time, except that bagasse can easier utilize (as making papermaking, making sheet raw material and making fuel),, all do not obtain satisfied effect though have many technical schemes to occur to the improvement and the utilization of other wastes.Have in the prior art scheme: agricultural filling method, oxidation pond process, biogas method, boiler flue circulate towards grey method, coagulant precipitation filtration method, method of enrichment, concentrated spray desiccating method, combustion method, make the fertile method of compound etc.These methods be not exist working cost height, energy consumption big, administer not thoroughly, have bad, the complex process of operability exactly, and have such or such problem such as secondary pollution.On the other hand, the organic fertilizer production needs a large amount of organic raw material again, containing in sugar industry liquid and waste slag produced has a large amount of available resources, wherein, has a lot of available compositions in the concentrated solution of molasses alcohol waste liquid, its component ratio is: solid substance is 69.2, organism is 37.9, and residual sugar is 14.3, and protein is 22.25, N is 3.56, P 2O 5Be 0.15, K 2O is 4.78; Can utilize composition also a lot of in the filter mud, its component ratio is: organic matter is 47.86, and robust fibre is 17.28, and protein is 14.38, and N is 2.3, P 2O 5Be 0.17, K 2O is 0.49.These resources then can both made a profit aspect economic benefit and the social benefit two simultaneously if can be converted into the raw material of organic fertilizer industry, are the major progress on prior art.
In the prior art, only have the single processing of molasses alcohol waste liquid and the method for producing fertilizer.As: number of patent application is that 96107697 (publication number is CN1143621A), name are called " method of producing organic fertilizer from dry powder of alcohol waste liquid ".This method does not belong to fermentation technology, just the dry powder of molasses alcohol waste liquid is mixed with other materials mixed fertilizer.This method facility investment is big, running cost is high, and the dry powder of producing is moisture absorption caking very easily, has limited its application.This method is adopted in production practice seldom, the also basic not operation of adopting.Recently, for molasses alcohol waste liquid, bagasse, filter mud etc. are carried out comprehensive treating process and utilization, the Chinese patent name is called " utilizing molasses alcohol waste liquid to produce the active organic compound fertilizer method " (patent No.: patent 97112080), microbial function microbial inoculum (vinelandii, phosphate solubilizing bacteria, potassium solubilizing bacteria etc.) is provided when providing by waste self thermophilic fermentation, thereby increases fertilizer efficiency.This method has fermentation procedure, than being progress with molasses alcohol waste liquid dry powder with other fertilizer material mixing gained mixed fertilizer, but still has following shortcoming:
