Claystone-activated carbon fiber water purification and filtration system

Abstract

The invention relates to a claystone-activated carbon fiber water purification and filtration system. The claystone-activated carbon fiber water purification and filtration system comprises a water conveying device, a water draining main pipe and a claystone-activated carbon fiber filtering device, wherein the water conveying device is communicated with the claystone-activated carbon fiber filtering device; the claystone-activated carbon fiber filtering device is communicated with the water draining main pipe; the claystone-activated carbon fiber filtering device is provided with a claystone-activated carbon fiber medium layer and an air-distributing structure layer respectively; the claystone-activated carbon fiber medium layer comprises three filtering layers, namely a modified bentonite filtering layer, an activated carbon fiber filtering layer and a zeolite filtering layer, which are arranged from top to bottom sequentially; a certain space is reserved above the modified bentonite filtering layer and the zeolite filtering layer; and the air-distributing structure layer is positioned on the lower part of the claystone-activated carbon fiber medium layer and is communicated with the claystone-activated carbon fiber medium layer. After breeding organic sewage is treated by the claystone-activated carbon fiber water purification and filtration system, the result shows that the removal rate of ammonia nitrogen is 42 to 48 percent, the decoloration rate is 64 to 68 percent, and good water purification effect is achieved.

Description

technical field [0001] The invention relates to a water purification and filtration system for removing or reducing various pollutants in sewage by using the physical and chemical adsorption properties of a solid adsorbent in water purification treatment, in particular to a clay rock-activated carbon fiber water purification and filtration system for purifying aquaculture sewage. Background technique [0002] The use of adsorption for material separation has a long history. It can effectively remove a variety of pollutants in sewage, including various dissolved organic matter, color, especially toxic substances, heavy metals, and refractory pollutants that are difficult to effectively remove by other methods. . As an important sewage treatment method, the adsorption method has a wide range of applications and a good treatment effect. With the continuous improvement of human's environmental and ecological requirements, adsorption method is playing an increasingly important r...

AI Technical Summary

Problems solved by technology

At present, although the water purification and filtration system using activated carbon as the main adsorbent used in water treatment has a good treatment effect, due to the high price of activated carbon, the operating cost of this type of water purification and filtration system using it as the main adsorbent remains high

Moreover, the pure water backwash method adopted by the filtration system consumes a lot of water, takes a long time to backwash, and has poor results, which limits the wide application of adsorption methods.
