Culture medium and culture method for cultivating Botry coccus braunii by utilizing monosodium glutamate plant wastewater

Abstract

The invention discloses a culture medium and culture method for cultivating Botry coccus braunii by utilizing monosodium glutamate plant wastewater. The technique can treat monosodium glutamate plant wastewater at low cost, utilize waste, change wastes into valuable substances and obtain the Botry coccus braunii with important economic value, thereby implementing multiple purposes. The traditional culture medium for Botry coccus braunii is the Zhu's No.13 culture solution which has the defects of low growth speed, low yield, high investment, high tendency to pollution and low benefits. In the invention, a closed circular cement track tank, which has the advantages of low cost and low tendency to pollution and is easy to operate, is utilized for culture; the monosodium glutamate plant wastewater, sodium fluoride, soil extract, sea mud extract, cattle manure extract, chicken manure extract, L-arginine, potassium dihydrogen phosphate, sorbitol, mannitol, sodium thioglycolate and the like are added to the culture medium, and the organic fertilizers and inorganic fertilizers are mixed; and thus, the nutrients are more comprehensive and balanced, the growth speed of the Botry coccus braunii is greatly enhanced, and the yield is enhanced by 320%.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a culture medium and a cultivation method for cultivating Polygonum algae by using waste water from a monosodium glutamate factory. Background technique [0002] MSG factory wastewater is a kind of high-concentration organic wastewater, which has the characteristics of high CODcr, BOD5, bacteria content, sulfate radical, ammonia nitrogen content and low pH value, that is, six high and one low. The annual wastewater discharge of my country's MSG industry is as high as 10 million tons, and the COD is as high as 50,000-60,000 mg / L, and the pH is unstable and smelly. If it is directly discharged into the river, it will not only waste the organic matter in the wastewater, but also seriously pollute the environment. . The traditional treatment methods of monosodium glutamate factory wastewater are as follows: [0003] 1. SBR method [0004] The SBR method is the abbreviation of...

Problems solved by technology

[0012] Disadvantages of SBR method: troublesome design, large investment in infrastructure construction, high organic matter content in the water outlet, troublesome management and operation, time-consuming and laborious, and low economic benefits

[0018] 2. Disadvantages

[0019] (1) When using a biological contact oxidation tank, if the design or operation is improper, it is easy to cause plugging of the filler and affect the treatment effect;

[0020] (2) This scheme requires too many structures, occupies a large area, and requires a large construction investment;

[0021] (3) The effluent after treatment is still turbid, and the removal rate of organic matter is low;

[0022] (4) More fillers and filler support structures are required

But the disadvantage is that it occupies a large area, the operation is troublesome, the treatment effect is greatly affected by the weather, temperature and production process, and the infrastructure investment is large.
