Embodiment Construction

[0049] Examples, in order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the examples. The example uses the betaine production wastewater of Shandong Xiangweisi Biotechnology Co., Ltd. as a sample.

[0050] In conjunction with accompanying drawing, a kind of betaine production wastewater treatment process comprises following processing steps:

[0051] a) Ozone oxidation, after the waste water is collected by the comprehensive adjustment tank, it is pumped into the ozone oxidation tank for ozone oxidation.

[0052] b) Hydrogen peroxide oxidation, the wastewater oxidized by ozonation enters the hydrogen peroxide oxidation tank, and the oxidant hydrogen peroxide is added according to the proportion, and the oxidation treatment is carried out for 4 hours.

[0053] c) Ph callback attenuation, the wastewater after oxygen balance enters the ph callback pool, the lye dosing pump is controlled by th...

Abstract

The invention relates to a betaine production wastewater treatment process, which comprises the following process steps: pre-treating: collecting mixed wastewater through a comprehensive adjusting tank, pumping into an ozone oxidation tank by a pump, carrying out ozone oxidation, introducing into a hydrogen peroxide oxidation tank, proportionally adding hydrogen peroxide, oxidizing for 4 hours, adjusting the oxidized wastewater to 7 through a pH back-regulating tank by controlling an alkali adding pump with a pH meter, carrying out aeration attenuation, removing excess hydrogen peroxide in thewastewater, and introducing into a biochemical system; and biochemical treatment: feeding the pretreated wastewater into a hydrolytic acidification tank, treating by anaerobic microorganisms in the tank, then feeding into a contact oxidation tank, digesting, decomposing and degrading the organic matters in the water by aerobic bacteria, and finally carrying out mud-water separation by a membranein an MBR tank, wherein the effluent achieves discharge standard. The method has the characteristics of convenience in use, small occupied area, high treatment efficiency, low energy consumption, small sludge yield and the like.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, and more specifically, relates to a process for treating wastewater from betaine production. Background technique [0002] Betaine is an important organic chemical, widely used in feed additives, food, cosmetic additives, detergents, raw materials for the production of monosodium glutamate in the food industry, and production materials for pharmaceutical materials such as vitamins and tylosin. In my country's feed industry, betaine is widely used instead of methionine to reduce the cost of breeding and make up for the lack of my country's heavy dependence on imports of methionine; another important use of betaine is for biological fermentation, which can be used as monosodium glutamate, vitamin B2, etc. The fermentation substrate of pharmaceutical raw materials, the application of betaine can greatly change the state of the fermentation industry with grain as the fermentation substrat...
