Abstract

The invention belongs to the technical field of wastewater decolorization treatment, and in particular relates to a molasses alcohol wastewater decolorizer, comprising decolorizer A and decolorizer B, and the components of the decolorizer A are grouped according to weight: 1-10 parts of activated carbon, diatomaceous earth 5-10 parts, 10-15 parts of ethyl hypochlorite, 5-10 parts of calcium hypochlorite, 8-20 parts of sodium hypochlorite, 3-7 parts of polypropylene alcohol, 0.8-2 parts of chelating agent; the decolorizing agent B The bacterial solution composed of Aspergillus niger, nitrifying bacteria, Bacillus subtilis, Bacillus licheniformis, Sporosporium thermophila, acetic acid bacteria and yeast is mixed at a volume ratio of 1‑1.5:1:1:1:1:1:1:1 The cell concentration of each bacterial solution was 1×10 9 cfu / ml. The present invention combines chemical oxidation, physical adsorption and biological treatment methods to decolorize molasses alcohol wastewater, solves the problems of long reaction time, low decolorization rate and poor effect, and has the advantages of rapid decolorization, high decolorization rate, good effect and no secondary pollution etc.

Description

【Technical field】 [0001] The invention relates to the technical field of wastewater decolorization treatment, in particular to a molasses alcohol wastewater decolorizer. 【Background technique】 [0002] Molasses alcohol wastewater is the high-concentration and high-color organic wastewater discharged after the alcohol workshop of the sugar factory uses molasses to ferment alcohol. It contains rich protein and other organic substances, and also contains more N, P, K, Ca, Mg Equal inorganic salts and higher concentration of SO4 2- Etc., if it is directly discharged without treatment, it will seriously pollute the water quality and the environment. Therefore, the molasses alcohol wastewater must be treated and can only be discharged after reaching the standard. However, since molasses alcohol wastewater is a type of high-concentration organic wastewater, the content of pigments in wastewater is relatively high, mainly composed of phenolic pigments, melanoids, caramel pigments, ...
