Embodiment 1

[0028] A company's xanthan gum production workshop adopts the following methods to treat production sewage

[0029] A method for controlling xanthan gum production sewage, characterized in that:

[0030] (1) First pass the xanthan gum wastewater through the grid to remove large suspended matter, and then lift it to the primary settling tank through the lift pump, and enter the regulating tank after being cooled by the cooling tower in the primary settling tank;

[0031] (2) Adjust the pH of the xanthan gum wastewater in the adjustment pool to 6.0-7.0, enter the sewage treatment system, add biological agents for advanced treatment, and then discharge it up to the standard.

[0032] The biological preparation is prepared by mixing a carrier and a composite microbial agent according to a weight ratio of 2:1, the carrier is chitosan, and the composite microbial agent is prepared from the following raw materials by weight:

[0033] Actinomycetes 10 parts, Aspergillus niger 10 part...

Abstract

The invention relates to a preparation for treating sewage produced by production of xanthan gum. The preparation is prepared from a carrier and a compound microbial agent; a method for treating the sewage with the preparation comprises the steps of firstly, enabling waste water of the xanthan gum to pass through a grid to remove big suspended matters; then, lifting the waste water into a primary settling tank by a lifting pump; cooling the waste water by a cooling tower in the primary settling tank, and then enabling the waste water to enter an regulation tank; and adjusting the pH of the waste water of the xanthan gum to be 6.0-7.0 in the regulation tank, enabling the waste water to enter a sewage treatment system, feeding the microbial agent, carrying out advanced treatment, and discharging the waste water when the waste water reaches the standard. The preparation is economic and environment-friendly, low in price, high in operability and wide in application scope.

Description

technical field [0001] The invention relates to the field of waste water treatment in the biological fermentation industry, and specifically provides a preparation for treating waste water from xanthan gum production. Background technique [0002] Xanthan gum (xanthan gum) is a neutral water-soluble polysaccharide that was discovered by Northern Regional Research Laboratories (NRRL) from Xanthomonas cam pestris (Xanthom onas cam pestris) NRRL B21459 in the 1950s. , also known as xanthan gum. It is a microbial extracellular heteropolysaccharide composed of glucose, mannose and glucuronic acid in a molar ratio of 218:2:2. Its "pentasaccharide repeat unit" main chain consists of two D-glucose molecules via β-1 , connected by 4 glycosidic bonds, has a cellulose-like skeleton structure, and a carbon bond in every 2 glucose is connected with a trisaccharide side chain composed of 2 mannans and 1 glucuronic acid. The unique molecular structure of xanthan gum endows it with many...
