Abstract
The invention relates to the feed field, and concretely relates to a protein feed produced by waste water from monosodium glutamate production. The method comprises the following steps: 1)heating monosodium glutamate waste water, boiling, concentrating and disinfecting, wherein the water content is 60-70%; 2) adding quicklime for neutralizing acidity until the pH value is neutral; 3)adding 2-5% of microzyme for fermenting, controlling the temperature at 32-37 DEG C, wherein the fermentation time is 60-70 hours; 4)drying the fermented semi-finished product; and 5) crushing the dried substance to obtain the protein feed. The protein feed produced by waste water has the beneficial effect that the protein feed is produced by monosodium glutamate waste water, refuse can be used again, added value of the raw material monosodium glutamate is fully performed, on the other hand, waste water is processed, so that the environment pollution problem due to waste water discharge is solved, the requirements of experiment equipment and experiment condition are low, and the experiment method has the advantages of easy operation.
Description
Technical field
The present invention relates to field of fodder, a kind of waste water of producing monosodium glutamate that utilizes is produced protein feed specifically.
Background technology
Tens of existing Gourmet Powder Factories of China, the overwhelming majority produces monosodium glutamate take grain as fermenting raw materials, produces nearly 500,000 tons of monosodium glutamate per year, and nearly 7,000,000 tons of discharge gourmet powder waste water, is high-concentration acidic wastewater organic wastewater, and environment is caused greatly and polluted.In waste water, mainly contain the pollutants such as starch, carbohydrate, protein, spent acid and salkali waste, also contain a large amount of thalline, with the difference of production technology, the COD concentration in waste water is between 2000～20000mg/l.If these starch wastewaters are without processing directly discharge, contained organic matter in its water, after entering water body, consume rapidly the dissolved oxygen in water, cause water hypoxia and affect the existence of fish and other aquatic animals, in waste water, suspension easily under anaerobic decomposes and produces foul smell simultaneously, worsens water quality.At present, also imperfect improvement technology of the world, is all generally after waste water mixed diluting, to discharge.
Summary of the invention
According to above-mentioned weak point, the object of this invention is to provide a kind of waste water of producing monosodium glutamate that utilizes and produce protein feed.
For achieving the above object, technical scheme of the present invention is, a kind of waste water of producing monosodium glutamate that utilizes is produced protein feed, and it comprises
1, gourmet powder waste water heating is boiled to concentrated and sterilizing, making water content is 60-70%;
2, adding neutralization with lime acidity, is neutral to pH;
3, the saccharomycete of interpolation 2-5% ferments, and control temperature is 32-37 ℃, fermentation time 60-70h;
4, the semi-finished product after fermentation are dried;
5, will be dried rear material and pulverize to obtain protein feed.
The invention has the beneficial effects as follows: by gourmet powder waste water fermentation production of protein feedstuff, not only can make refuse again utilize, give full play to the added value of monosodium glutamate raw material, on the other hand, process waste water, solved discharge of wastewater and cause the problem of environmental pollution, killed two birds with one stone, the present invention is not high to experimental facilities and requirement for experiment condition, and experimental technique is simple.
