Research On Comprehensive Management Of Lees And Its Waste Solution

There are many management methods on lees and waste solution;however,most of them are single management. There are many biological methods that have complicated procedure,strict operation technique and heavy instrument investment. We conduct research on related control condition and procedure parameter,for exploitation of comprehensive use of live bacteria forage that takes lees as main material,biological organic fertilizer,let of firedamp waster solution.1 .We conduct research on fermentation forage production technique that takes lees and straw as material. After single factor experiment and multiple factors orthogonal experiment,we determine the ingredients of fermentation material. The main procedure parameter:PH 6.0,induction quantity 2.0%,fermentation temperature 30 ,the fermentation time is 5day ,index of main nutrition ingredients in production of fermentation forage such as the crude protein,soluble protein,soluble sugar,dissociate amino acid was lifted 30% than before fermentation.2. We conduct research on procedure technique of fermentation biological organic fertilizer,based on the material of firedamp-dissolved residue and straw. After single comparison experiment and multiple comparison experiment,we determined the material proportion:25% waste lees and 25% straw,the fermentation time is 9day,inoculation quantity is 1.0%,main index of containment of humic acid is38.4%.3. We conduct the research on biological management technique of waster solution of alcohol fermentation and firedamp dissolved solution,after single factor experiment,we determined all the procedure condition of management of fermentation waster solution. The result of orthogonal experiment,Experiment shows that temperature is the main factor,the most appropriate temperature is 30,inoculation quantity is 0.5%,and the most appropriate PH is 6.0. We still do some research on waste water management using coagulaion agent,and determined the best coagulaion agent and addition quantity,waste water after management is allowed to let by the national secondary comprehensive gauge.The research on comprehensive management of lees and its waste solution,make waste secondary resource reasonable use,is accordance with national sustainable strategy,and is important on alleviation of shortage of forage resource,improving national water resource environment.
