Problems solved by technology

In the process of processing, due to the conventional pressing and drying method, a large amount of waste liquid is directly discharged without treatment, forming secondary pollution; the waste contains a large amount of protein and other nutrients that have not been effectively utilized, resulting in waste

Embodiment Construction

[0011] A kind of method of processing water hyacinth feed with osmotic membrane of the present invention, concrete operating steps are as follows:

[0012] Take 1000 kg of fresh water hyacinth of the whole plant, crush it and squeeze the juice to obtain 220 kg of wet residue and 780 kg of water hyacinth juice respectively. Here, what we have adopted is the pulverizing and squeezing process, and the juice yield reaches 78% (percentage by weight).

[0013] Preparation of composite strains: Saccharomyces cerevisiae and Lactobacillus were selected as the initial strains of microbial strains. Take 20kg of wet water hyacinth slag, add 1000ml of Saccharomyces cerevisiae culture solution and 1000ml of Lactobacillus culture solution, mix thoroughly, and culture at 25-30°C for 48 hours, then air dry for later use.

[0014] The above-mentioned water hyacinth juice is first filtered, concentrated by nanofiltration membrane (operating pressure is 0.8~1mpa), crystallized, filtered, and the...

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 [0001] The invention relates to a method for processing water hyacinth feed with a permeable membrane. Background technique [0002] Scientific research has confirmed that water hyacinth has a strong ability to purify sewage. Under suitable conditions, one hectare of water hyacinth can absorb the nitrogen and phosphorus elements discharged by 800 people in one day. The growth and reproduction speed of water hyacinth in nutrient-rich water is almost crazy. If it is not salvaged in time, it will cover the water surface, block the river, affect shipping, power generation, irrigation and flood discharge, and eventually rot and smell, pollute the water quality and destroy the ecology of the water body. At present, most of the redundant water hyacinths salvaged by people are landfilled, which produces a large amount of malodorous gas, combustible gas and landfill leachate, causing serious secondary pollution. Although planting water hyacinth in polluted waters is ...
