Abstract
The invention relates to a method for processing a water hyacinth fodder by a permeable membrane. The method has the technological steps of: (1) crushing and extracting fresh water hyacinth powder to obtain wet slag and water hyacinth juice; (2) filtering the water hyacinth juice, and then circularly filtering by a membrane separation technology to remove most of water in the water hyacinth juice and obtain filtering slag; (3) introducing a microorganism strain into the wet slag and the filtering slag, drying and fermenting, and then obtaining water hyacinth fodder dry powder. The membrane for the membrane separation technology is a nano filter membrane, the operation pressure is 0.8-1mpa, and the microorganism strain is a compound strain cultured by saccharomyces cerevisiae and lactobacillus. By adopting a permeable membrane technology and a microorganism anti-mildew technology, harmless processing is carried out on the water hyacinth to produce green and harmless animal fodder. By adopting the invention, the processing site can be arranged beside the water field where the water hyacinth grows, the cost of transporting the water hyacinth is saved, the standard wastewater can be directly drained into the water field, and the processed water hyacinth dry powder is a good animal fodder.
Description
Technical field
The present invention relates to a kind of method with the permeable membrane processing water hyacinth fodder.
Background technology
Scientific research confirms that water hyacinth has the very strong ability of purifying waste water, and under suitable condition, one hectare of water hyacinth can sponge the nitrogen P elements of 800 people discharging the same day.Water hyacinth speed of growth and breeding in eutrophic water body is almost crazy, if untimely salvaging can cover the water surface, stop up the river course, influences shipping, generating, irrigation and drainage, flood discharge, and final rotting fouled, and polluted water destroys water ecology.It is landfill disposal that present people salvage the exhausted major part of unnecessary water hyacinth, produces a large amount of foul gas, fuel gas and percolate thus again, causes serious secondary pollution.Though by being the effective way of administering water body at polluted water region plantation water hyacinth, because bright water hyacinth water content is up to 95%, remote cost of transportation height, and rotting easily, this gives and handles water hyacinth and bring difficulty.
The research to the water hyacinth comprehensive utilization both at home and abroad mainly contains: make furniture, directly as feed, make biogas, as edible fungi raw materials, make organic fertilizer, as the health products raw material, as fuel etc.In process, owing to adopt conventional squeezing filter drying method, the discarded in a large number not treated direct discharging of liquid forms secondary pollution; Contain nutritions such as a large amount of protein in the discarded object and be not utilized effectively, cause waste.
Summary of the invention
Purpose of the present invention is that a kind of method with the permeable membrane processing water hyacinth fodder will be provided, and uses this method, and the processing site is located on the limit, waters, removes a large amount of freights from; The discharge liquid that adds man-hour reaches environmental requirement, can directly enter waters, non-secondary pollution; Processing back end product quality height has an economic benefit.
A kind of method of the present invention with the permeable membrane processing water hyacinth fodder, its processing step is:
(1) bright water hyacinth pulverizing is squeezed the juice, obtain wet slag and water hyacinth juice;
(2) with above-mentioned water hyacinth juice earlier after filtration, use the membrane separation technique circulating filtration then, remove the most moisture in the water hyacinth juice, obtain filter residue;
(3) microorganism fungus kind is inserted in wet slag and the filter residue, limit dry limit fermentation gets water hyacinth fodder dry powder.
The used film of membrane separation technique of the present invention is a NF membrane, and operation pressure is 0.8~1mpa; Described microorganism fungus kind is the composite bacteria that saccharomyces cerevisiae+Bacillus acidi lactici is cultivated.
The invention has the beneficial effects as follows, adopt the anti-technology of going mouldy of infiltrate membrane technology and microorganism, water hyacinth is carried out harmless processing, make the green non-pollution animal feed.
The specific embodiment
A kind of method of the present invention with the permeable membrane processing water hyacinth fodder, the concrete operations step is as follows:
Get the bright water hyacinth 1000kg of complete stool, its pulverizing is squeezed the juice, obtain wet slag 220kg and water hyacinth juice 780kg respectively.At this, what we adopted is to pulverize squeezing process, and crushing juice rate reaches 78% (percentage by weight).
The composite bacteria preparation: it is initial bacterial classification that microorganism fungus kind is selected saccharomyces cerevisiae and Bacillus acidi lactici for use.Get the water hyacinth wet slag of 20kg, insert saccharomyces cerevisiae nutrient solution and each 1000ml of Bacillus acidi lactici nutrient solution, after fully mixing, under 25-30 ℃ of temperature, leave standstill and cultivate after 48 hours, air-dry standby.
Above-mentioned water hyacinth juice earlier after filtration, NF membrane concentrates that (operation pressure is 0.8~1mpa), crystallization, filtration, filtrate enters the circulation that NF membrane concentrates once more, the final higher water hyacinth filter residue of protein content that gets, it is mixed with the wet slag that obtains before, and access 5kg composite bacteria, treat its fermentation after 18 hours, the employing natural-wind dry obtains the 50kg protein content and is about 20% dry powder of water hyacinth feed.The water that leaches is directly discharging then.
Adopt the present invention, the processing site can be located at by the waters of growth water hyacinth, saves the expense of transport of water cucurbit, and waste water up to standard directly enters the waters, and processing gained dry powder of water hyacinth is a kind of good animal feed.
Claims (2)
1. method with the permeable membrane processing water hyacinth fodder, its processing step is:
(1) bright water hyacinth pulverizing is squeezed the juice, obtain wet slag and water hyacinth juice;
(2) use the NF membrane isolation technics, remove the moisture in the water hyacinth juice, obtain filter residue;
(3) composite bacteria that saccharomyces cerevisiae+Bacillus acidi lactici is cultivated inserts in wet slag and the filter residue, and limit dry limit fermentation gets water hyacinth fodder dry powder.
2. according to the described a kind of method with the permeable membrane processing water hyacinth fodder of claim 1, it is characterized in that: the operation pressure of described NF membrane is 0.8~1mpa.
