Embodiment Construction
[0032] The device and method for treating high-concentration refractory organic wastewater provided by the invention can quickly remove pollutants (such as organic matter, inorganic matter, microorganisms, heavy metals, etc.) in sewage.
[0033] see figure 1 . The treatment device for high-concentration refractory organic wastewater provided by the present invention has a main structure comprising:
[0034] The bottom of the anaerobic biofilm reactor 4 is provided with a mud discharge hole 22, and the inside of the anaerobic biofilm reactor 4 is located above the mud discharge hole 22 and is provided with an aeration pan, and an agitator 32 is arranged above the aeration pan; the high temperature anaerobic biofilm The reactor 4 is filled with composite packing 5, which is composed of biofilm growing on the surface of the packing. The high-temperature environment in the anaerobic biofilm reactor 4 kills microorganisms and pathogenic bacteria, and at the same time rapidly deco...

Abstract
The invention relates to a device for treating high-concentration and degradation-resistant organic waste water. The device for treating the high-concentration and degradation-resistant organic waste water mainly comprises an anaerobic bio-membrane reactor, an aerobic bio-membrane reactor, an artificial wetland system, a turbine sieve filter and a sand setting tank. The invention also discloses a method for removing high-concentration organic pollutants in sewage by utilizing the device provided by the invention. The device and method for treating the high-concentration and degradation-resistant organic waste water have the advantages that a nano aeration technology is adopted, two methods, namely photoexcitation and photocatalysis, are combined, hydroxyl free radicals are produced at high efficiency, biologically treated sewage effluent is subjected to deep treatment in a lasting and effective manner by utilizing strong oxidizing property of the hydroxyl free radicals, the pollutants with poor biodegradability and relative high molecular weight can be completely oxidized and degraded, and bacteria and pathogenic bacteria in sewage are killed, so that the sterilization and disinfection effects are realized.
Description
technical field [0001] The invention relates to an advanced treatment device for high-concentration refractory organic wastewater. [0002] The invention also relates to a method for removing pollutants such as high-concentration organic matter in sewage by using the device.
