Integrated treatment device for granular activated carbon-SBR (Sequencing Batch Reactor) high salt organic wastewater

Abstract

The invention relates to an integrated treatment device for granular activated carbon-SBR (Sequencing Batch Reactor) high salt organic wastewater, belonging to the field of sewerage treatment of environmental engineering. The integrated treatment device is mainly divided into two regions of a water-quality regulation region and a main reaction region, wherein a stirrer is arranged in the water-quality regulation region, the water outlet of the water-quality regulation region is communicated with the main reaction region through a feed pipeline, a feed-water pump is installed on the feed pipeline, another stirrer, an aerator, a dissolved oxygen meter and a decanter are installed in the main reaction region, the aerator at the bottom is communicated with a fan, the discharging pipeline of the decanter discharges water, the soil discharging opening at the bottom of a main reactor is communicated with a soil discharging pipeline, and granular activated carbons are filled in the main reactor. In the invention, aiming at the characteristics of the high salt organic wastewater, a biotechnology and an activated carbon technology are effectively combined, the granular activated carbons are added to an SBR system, the adsorption of the activated carbons is combined with biodegradation through fluidization of an activated carbon carrier so that the adsorption and the biodegradation are displayed, and different kinds of organisms are effectively degraded.

Description

technical field [0001] The invention belongs to the field of environmental engineering sewage treatment, in particular to an integrated device for processing high-salt organic waste water coupled with SBR process. Background technique [0002] High-salt organic wastewater treatment technology: In addition to being limited by its own high concentration of salt, high-salt organic wastewater also contains a large amount of toxic and refractory organic substances. It is best for this type of wastewater to be pretreated before being discharged into municipal pipelines. At present, more effective processes for treating such wastewater include electrochemical methods, membrane separation methods, incineration methods, and biological methods. Electrochemical method, membrane separation method, and incineration method are difficult to achieve large-scale application due to small treatment scale, high treatment cost, and secondary pollution. Biological method is the most traditional ...

AI Technical Summary

Problems solved by technology

However, activated carbon water treatment technology also has its own shortcomings.

First, the main characteristic of activated carbon is adsorption, which cannot effectively degrade organic matter

Second, if the regeneration and recovery of activated carbon is not realized after the adsorption is saturated, the activated carbon will be used in large quantities, resulting in a significant increase in operating costs
