Treating process of amino acid fermenting effluent

Abstract

Up to now, the perfect treatment of amino acid fermenting effluent has become the key for amino acid producing enterprise to develop, and the present invention is one perfect technological process of treating amino acid fermenting effluent. The technological process includes the main steps of concentrating, spraying slurry to pelletize, washing and dedusting, electrostatic treating, biochemical treating, etc. and converts the fermented effluent into valuable compound fertilizer, clean water and gas. For the first time, the technological process adopts a sweeping, catching and vapor chromatography-mass spectrometry method for determining the components of pelletizing tail gas identified as aerosol; develops electrostatic technology and apparatus for treating the slurry spraying second pelletizing tail gas; and develops the electrostatic treatment to enrich high concentration organic effluent.

Description

technical field

[0001] The invention belongs to the technical field of reuse of industrial and agricultural production effluents, relates to amino acid fermentation and related industries, in particular to a waste liquid treatment process in the amino acid fermentation industry. Background technique

[0002] At the same time of economic development, the pollution to the environment is increasing, especially in the amino acid fermentation industry, the pollution of fermentation waste liquid is even greater. Although a lot of exploration and efforts have been made in this regard, and many achievements have been made, it is still different from the current There is still a gap in the requirements for environmental protection, and there are still problems such as large investment, unsatisfactory results, or high operating costs [Xu Hanxiang. Sewage treatment in the monosodium glutamate industry [J]. Light Industry and Environmental Protection, 1996, 18(1): 33-37. Sun Zhenshi, Ch...

[0034] This technology was first applied to Baoji Fufeng Fermentation Biotechnology Co., Ltd. of Shandong Fufeng Fermentation Group. The main product of Baoji Fufeng Fermentation Biotechnology Co., Ltd. is glutamic acid. In the early stage of production, because the fermentation waste liquid could not be completely treated, it could not pass the acceptance of the environmental protection department, forcing the factory to limit production, stop production, and rectify within a time limit until it reached the standard. After adopting this treatment process, the fermentation waste liquid has been thoroughly treated, successfully passed the inspection and acceptance of the environmental protection department, and won precious time for the enterprise. It was put into production that year, bringing a net profit of more than 200 million yuan, and achieved obvious results. economic and environmental benefits.
