Accelerant for biological treatment of dimethyl ether waste water

Abstract

The invention discloses dimethyl ether industrial sewage living creature treating accelerant, which can be confected through the mixing of solid soot powder, dried substrate sludge in the river or the lake, and dried mud in the city according a certain proportion. As the accelerant of the dimethyl ether industrial sewage living creature treating, the invention can accelerate the germiculture process of the living creature treating, shorten the domestication time of the culture, improve the living creature treating efficiency, and strengthen the effect of the living creature treating. The accelerant has good stability, simple, convenient and easy preparation method, easy obtaining of raw materials, no need of a special apparatus, good reappearing performance, in particular low cost, wide use, and friendly environment, thereby being used for the living creature treating process of the single component organic sewage such as dimethyl ether sewage producing sewage.

Description

technical field [0001] The invention relates to a biological treatment process of dimethyl ether industrial waste water, in particular to a biological treatment accelerator for industrial organic matter waste water discharged during the production process of dimethyl ether, a preparation method and application thereof. technical background [0002] Due to the lack of nutrients such as N and trace elements in the biochemical treatment process of single dimethyl ether product wastewater, the growth of microorganisms in the biological treatment system is unhealthy, and various abnormal situations are prone to occur, such as the biochemical debugging process of the wastewater treatment system takes a long time and has low efficiency ; The domestication rate of activated sludge is low, and the removal effect of organic matter is poor; when the methanol content is high, the growth and reproduction of microorganisms are obviously inhibited, the number of microorganisms is small, and...

Problems solved by technology

[0002] Due to the lack of nutrients such as N and trace elements in the biochemical treatment process of single dimethyl ether product wastewater, the growth of microorganisms in the biological treatment system is unhealthy, and various abnormal situations are prone to occur, such as the biochemical debugging process of the wastewater treatment system takes a long time and has low efficiency ; The domestication rate of activated sludge is low, and the removal effect of organic matter is poor; when the methanol content is high, the growth and reproduction of microorganisms are obviously inhibited, the number of microorganisms is small, and the species is single; the adaptability of microorganisms to changes in water quality fluctuations is poor, the quality of effluent water is poor, and the operation is unstable. Difficulty in operation and management

In order to improve the biochemical treatment effect of dimethyl ether wastewater, the method of adding traditional N, P and other supplementary nutrients is usually used, but it is often easy to cause serious corrosion and fouling of pipelines and equipment, and the operating cost is high, making it difficult to apply on a large scale
