Integrated biological powdered activated carbon adsorption and precipitation device and application method thereof

Abstract

The invention discloses an integrated biological powdered activated carbon adsorption and precipitation device and an application method thereof. The method comprises the following steps: allowing sewage to be treated to enter an adsorption area, throwing powdered activated powder in the adsorption area, adsorbing organic matters, performing the aerobic aeration for the adsorption area, facilitating the growth of bacteria on the surface of the powdered activated powder, facilitating the nitration, allowing the water discharged from the adsorption area to enter a refluxing area, throwing a carbon source in the refluxing area, facilitating the denitrification, then allowing the sewage to enter an ascending area, when the sewage passes through a three-phase separator, scattering the denitrification nitrogen in the sewage into the air by virtue of a release pipe, allowing the sewage to enter a floating bed precipitation area, separating carbon from the sewage to enter a sludge hopper, and allowing the sewage to be discharged out of the device by virtue of a water outlet overflow weir. By adopting the integrated biological powder activated carbon adsorption and precipitation device and the application method thereof, the organic matters which are difficult to biochemically degrade in the waste water are removed with relatively low operation expense; and meanwhile, by virtue of biological enhancement on the powdered activated carbon carrier, a function for removing ammonium nitrogen and total nitrogen can be realized.

Description

technical field [0001] The invention relates to a sewage advanced treatment device and its use method, in particular to an integrated biological powder activated carbon adsorption and precipitation device and its use method. Background technique [0002] At present, many sewage treatment plants in industrial enterprises or industrial agglomeration areas are difficult to meet the standards. The main reason is that the components of industrial sewage are complex, and the fluctuations in water quality and water volume are relatively large. The existing sewage treatment equipment is difficult to meet the requirements. [0003] The regeneration of activated carbon, especially powdered activated carbon, has been widely used in recent years. This will greatly reduce the cost of using powdered activated carbon to 20-30% of the price of existing powdered activated carbon, making it possible for activated carbon to adsorb organic matter. [0004] Considering the economy, the adsorpti...

Problems solved by technology

The second application is difficult to regenerate powdered activated carbon due to the mixing of a large amount of activated sludge, and the effect of recovery of adsorption performance after regeneration is also difficult to guarantee

[0006] Most industrial wastewater, especially biochemical wastewater from sewage treatment plants in industrial agglomeration areas, often has organic matter, ammonia nitrogen, total nitrogen and total phosphorus exceeding the standard in a small amount. The renewable powder activated carbon adsorption involved in the current technology is mostly used for the removal of organic matter. , it is difficult to remove ammonia nitrogen, total nitrogen and total phosphorus
