Problems solved by technology

However, in the process of evaporating a large amount of water vapor, the organic matter in the fermentation waste liquid is coked and decomposed under high temperature conditions, forming smoke that is difficult to diffuse, and has obvious odor and burnt taste, causing serious air pollution
In addition, fertilizers made at high temperatures of 500°C to 600°C have hidden dangers of soil pollution.
Because at a high temperature of 500°C to 600°C, the water-soluble substances in the slurry are prone to undergo condensation chemical reactions to form "high-temperature chemical bonds". After "high-temperature spray granulation", the original water-soluble substances undergo thermochemical reaction transformation Become water-insoluble or insoluble substances, it is difficult to decompose when applied to soil microorganisms, and there is also a potential pollution to the soil
Under the pressure of today's environmental protection requirements, the secondary pollution of the atmosphere and the hidden dangers of soil pollution caused by high-temperature spray granulation will seriously restrict the development of glutamic acid fermentation plants
[0005] 2. Fertilizers are not easy to meet the standards
[0006] In the process of high-temperature spray granulation to form fertilizers, the concentrated fermentation waste liquid is directly sprayed into mist droplets. Under high temperature conditions, the moisture in the mist droplets is dried to form solids. The fertilizer obtained by this process is relatively simple. It can only be the substance in the fermentation waste liquid, and its composition should not be changed
The fertilizer industry has national standards, and it is difficult for bio-fermentation (organic-inorganic compound) fertilizers made through "high-temperature spray granulation" to meet the standards of the fertilizer industry
[0007] 3. High energy consumption
[0009] 4. Large equipment investment and difficult organic waste gas treatment
These governance facilities not only require a large investment but also have a short lifespan, and the governance is still incomplete, which increases the economic burden on the enterprise
[0011] Due to the above shortcomings of the "high temperature spray granulation" process, especially the secondary pollution of tail gas and the hidden danger of soil pollution, the development of glutamic acid fermentation plants has been seriously restricted.

Abstract

The invention discloses a method for producing a biological fermentation compound fertilizer by fermenting organic waste water with glutamic acid, which mainly comprises the following steps: carrying out multiple-effect evaporation concentration on waste liquor fermented by glutamic acid, extracting mycoprotein, carrying out multiple-effect concentration, carrying out low-temperature spraying fluidized granulation (adding inorganic constituents), screening, and cooling to obtain the finished biological fermentation compound fertilizer product. The method can overcome the defect that organic substance constituents can be coked and decomposed at high temperature, causing secondary pollution on the atmosphere and soil pollution caused by carbides in the spouting granulation technique, and develops a creative way for realizing zero discharge of organic waste water.

Description

technical field [0001] The invention relates to a production method of compound fertilizer, in particular to a method for producing biologically fermented compound fertilizer by using glutamic acid to ferment organic waste water. Background technique [0002] At present, most glutamic acid fermentation production enterprises produce glutamic acid through biological fermentation, and react with sodium hydroxide or sodium carbonate to form monosodium glutamate (monosodium glutamate). The main process flow is: starch → glucose → (biological fermentation method) → glutamic acid → (refined) → monosodium glutamate (MSG). Extract glutamic acid from the fermentation broth to become fermentation waste liquid, which contains a large amount of bacteria, various fermentation intermediates and trace elements. After the bacterial protein is extracted from the fermentation waste liquid, the pH of the solution is between 1.7-3-3.5, the concentration of CODcr is about 20000mg / L, the concent...
