Abstract
The invention belongs to the technical field of environment protection and relates to a composite biomass fiber coagulant prepared from bagasse. The composite biomass fiber coagulant is prepared from, by mass, 60-70% of bagasse alcohol-alkaline filter liquor, 25-37% of a complexing agent and 3-5% of a catalyst. According to the composite biomass fiber coagulant, natural bagasse serves as the main compounding material, so that the recycle rate of waste in the sugar industry can be increased, and the effective ingredient of natural bagasse can be fully utilized; the composite coagulant is used for treating waste water and conforms to the current nation-initiated policy of reutilization and commercialization of industrial waste.
Description
Technical field
Patent of the present invention belongs to environmental technology field, is specifically related to the composite biomass fiber coagulating agent utilizing bagasse to prepare for raw material.
Background technology
Bagasse is the principal by product of sugar industry, is a kind of important renewable biomass resource. China is the 3rd big cane planting country being only second to Brazil and India, and the output of sugarcane district, south bagasse can reach more than 700 ten thousand tons. But the lignifying degree height due to bagasse, nutrient is inharmonious, and when bagasse is as animal-feed, organic matter digestibility only has about 20% or lower. In addition, bagasse directly be used as edible mushrooms planting material be also restricted. Owing to trans-utilization technique means falls behind, bagasse is often passed into disuse or majority is only used as fuel, and its utilization ratio is very low, not only causes the waste of resource, but also brings the pollution of environment.
Bagasse rich cellulose, xylogen, from the composition of bagasse it will be seen that it is the desirable starting material of synthesising biological matter fiber coagulating agent. At present, it is that raw material is prepared composite biomass coagulating agent and be have not been reported taking bagasse, therefore, prepares the new way that coagulating agent is bagasse recycling.
Carrying out the research of synthesis coagulating agent comprehensive utilization for bagasse, obtain high added value product, it is economical, social, environmental benefit is very considerable.
Summary of the invention
For solving the problem of complex utilization of bagasse, it take bagasse as the composite biomass fiber coagulating agent of Material synthesis that the present invention provides a kind of.
The present invention utilizes bagasse to prepare composite biomass fiber coagulating agent. By drying heating and decompose certain time in alcohol alkali mixing solutions that first bagasse after pulverizing make in glycerol and potassium hydroxide, get supernatant liquid filtration for subsequent use; Then catalyzer, recombiner and upper strata filtrate are injected hydrothermal synthesis reaction still reacting by heating certain time, it is cooled to room temperature, filtering reacting liquid body concentrating and precipitating, dry throw out i.e. obtained composite biomass fiber coagulating agent. Composite biomass fiber coagulating agent is bagasse alcohol alkali filtrate 60-70%, recombiner 25-37%, catalyzer 3-5% by each composition quality per-cent.
Utilize bagasse to prepare composite biomass fiber coagulating agent, it is possible not only to the repeating utilization factor improving sugar-refining industry waste, and waste water treatment can be carried out while effectively utilizing waste resource, meet the policy of the energy-saving and emission-reduction of current country, the treatment of wastes with processes of wastes against one another.

Embodiment two:
The bagasse learnt from else's experience and dry after pulverizing, be heated in volume ratio is the 3.5mol/L glycerol of 1:2 and the alcohol alkali mixing solutions of 1.5mol/L potassium hydroxide 50 DEG C clear up 10h after to get the filtrate of supernatant liquid for subsequent use; Then the ratio injection hydrothermal synthesis reaction still that catalyzer APG, recombiner guar gum and upper strata filtrate are respectively 4%, 30%, 66% according to mass percent is heated to 105 DEG C of reaction 4h, it is cooled to room temperature, filtering reacting liquid body concentrating and precipitating, dry throw out at 50 DEG C and namely obtain composite biomass fiber coagulating agent solid.
Embodiment three:
The bagasse learnt from else's experience and dry after pulverizing, be heated in volume ratio is the 2.5mol/L glycerol of 2:3 and the alcohol alkali mixing solutions of 2.5mol/L potassium hydroxide 55 DEG C clear up 9.5h after to get the filtrate of supernatant liquid for subsequent use; Then the ratio injection hydrothermal synthesis reaction still that catalyzer APG, recombiner Cassia bean gum and upper strata filtrate are respectively 5%, 25%, 70% according to mass percent is heated to 110 DEG C of reaction 3.5h, it is cooled to room temperature, filtering reacting liquid body concentrating and precipitating, dry throw out at 55 DEG C and namely obtain composite biomass fiber coagulating agent solid.
