Industrial wastewater treatment ectopic biological growth promoting enhancing method and device

Abstract

The invention provides an industrial wastewater treatment ectopic biological growth promoting enhancing method and device. The industrial wastewater treatment ectopic biological growth promoting enhancing device is characterized by comprising an aerobic tank and a bypass ectopic biological growth promoting reactor, the bypass ectopic biological growth promoting reactor is filled with biological growth promoting filler, and the biological growth promoting filler comprises iron-manganese alloy particles, iron-copper alloy particles, ceramsite, activated carbon, zeolite and limonite. By means of the bypass ectopic biological growth promoting enhancing method, activity of preponderant fungi in industrial wastewater aerobic biological treatment can be effectively improved, the number of the preponderant fungi in industrial wastewater aerobic biological treatment can be effectively increased, and accordingly the requirement for improving wastewater discharge standards is met. By means of the method, organic matter removal efficiency in industrial wastewater aerobic biological treatment can be improved by 30-40%, and investment and operation cost for treatment standard improvement supplement pre-treatment and deep treatment of industrial wastewater is reduced.

Description

technical field [0001] The invention relates to a technical field of industrial wastewater treatment, in particular to a method for enhancing industrial wastewater treatment by ex-situ biological growth promotion. Background technique [0002] At present, the discharge standards of industrial wastewater are generally raised. In the past, industrial wastewater treatment mostly followed the combination of anaerobic (or hydrolytic acidification), aerobic and other biological treatment processes. After the discharge standards were generally raised, it was difficult to meet the new discharge standards with this traditional combination process. However, industrial wastewater is limited by the toxicity and refractory nature of the water quality. Under the condition of natural aeration and growth in the aerobic biological treatment structure, the activity and quantity of the dominant bacteria that have a specific degradation effect on the degradation of organic matter are difficult ...

AI Technical Summary

Problems solved by technology

In the past, industrial wastewater treatment mostly used anaerobic (or hydrolytic acidification), aerobic and other biological treatment combined processes. After the discharge standards were generally raised, it was difficult to meet the new discharge standards with this traditional combined process.

However, industrial wastewater is limited by the toxicity and refractory nature of the water quality. Under the condition of natural aeration and growth in the aerobic biological treatment structure, the activity and quantity of the dominant bacteria that have a specific degradation effect on the degradation of organic matter are difficult to greatly increase. Organic matter degradation Efficiency is difficult to further improve

At present, the upgrading and transformation of industrial wastewater mainly focus on the two links of enhanced pretreatment and advanced treatment, but these two methods require new treatment facilities, and the new investment and operating costs are also relatively high.
