Problems solved by technology

[0005] Vitamin B 1 COD concentration of organic matter in production wastewater is generally 1000-10000mg / L, BOD 5 Mostly in 500~1500mg / L, sulfate content in 1200~1600mg / L, NH 4 + -N is mostly in the range of 100-400mg / L, with large chromaticity, large turbidity, large changes in water quality, complex and diverse components, containing a large amount of organic substances that are difficult to biodegrade, and poor biodegradability. It is difficult to meet the discharge standard with conventional treatment processes
Although there are many relevant pharmaceutical wastewater treatment processes in the existing literature, the relevant vitamin B 1 The treatment process of production wastewater is rarely reported

Embodiment 1

[0015] raw vitamin B 1 COD and SO in production wastewater 4 2- The contents were 2736 and 1282mg / L respectively, and the pH value was adjusted to 7.0 by adding sodium hydroxide, and then entered the anaerobic biological treatment system.

[0016] The anaerobic biological treatment system is an anaerobic composite bed reactor, the bottom is evenly distributed water, the lower part is a sludge suspension layer, and the upper part is equipped with a combined filler, in which the suspended anaerobic sludge grows and accumulates. The upper part of the reactor is equipped with Biogas collection device. Vitamin B 1 The residence time of production wastewater in the anaerobic stage is 12h, the reaction temperature is 35°C, the effluent enters the sedimentation tank, and the supernatant after precipitation enters the biological iron aerobic biological treatment system. COD in wastewater after anaerobic biological treatment is 1221mg / L, SO 4 2- It is 166mg / L.

Abstract

The invention relates to a method for treating vitamin B1 production waste water, which belongs to the technical field of the treatment of industrial sewage. The method comprises the following steps of: 1) adjusting the pH value of the original vitamin B1 production waste water; 2) performing anaerobic biochemical treatment; and 3) performing aerobic biochemical treatment. The vitamin B1 production waste water is treated by the method which combines anaerobic treatment and aerobic treatment, so that the method has the advantages of effectively treating high-concentration organic waste water produced in a vitamin B1 production process and greatly reducing environment pollution caused by waste water discharge, along with good effect, low cost and standard discharge.

Description

technical field [0001] The present invention relates to vitamin B 1 The invention relates to a treatment method for production waste water, which belongs to the technical field of industrial sewage treatment. Background technique [0002] With the development of industry, the discharge of industrial water and waste water is also increasing. The discharge of a large amount of wastewater not only wastes water resources, but also brings serious pollution to the environment, destroys the ecological balance, and also brings great harm to the growth of animals and plants and human life. In order to protect the environment and ensure human life and health, sewage treatment has attracted great attention in recent years. According to different water quality, different scientific methods are used to treat it, turning harm into benefit and turning waste into treasure. [0003] Vitamin B 1 Also known as thiamine or anti-neuritis, it mainly exists in the outer skin and germ of seeds, ...
