Abstract

This invention relates to water disposal facility and means of integrated ozone and aerating biological filter. This aerating biological filter(9) is above ozone catalysis chamber(8), connects with ozone catalysis chamber(8) through the filter plate of biological filter(9); ozone catalysis chamber joints with Venturi tube(5), Venturi tube(5) respectively joints with ozone occurring system(6) and influent water pump(1); ozone occurring system(6) is a ozonizer that by silent discharge method translate oxygen of air into ozone. The water after pretreatment by ozone passes the filter plate of the aeration biological filter pool at the top of the ozone reaction chamber to enter the biological filter pool uniformly and stay for about 1 to 4 hours. This invention can advance aerating efficiency without fixing aerating system, and the flow between aerating biological filter and ozonization buffer pool cell is equilibrium, possess merits of high efficiency, low cost and so on.

Description

technical field

[0001] The invention relates to the field of water treatment, in particular to the field of advanced treatment of polluted raw water and waste water, especially waste water containing refractory biodegradable organic matter, by using an integrated water treatment method of ozone and biological aerated filter. Background technique

[0002] Ozone has extremely strong oxidizing properties, and its oxidizing ability is second only to fluorine, higher than chlorine and potassium permanganate. Based on the strong oxidizing properties of ozone, it can be decomposed in water in a short time without secondary pollution, so it is an ideal green oxidizing agent. At present, ozone technology has been applied in many aspects in the field of water treatment. Ozone not only has a strong disinfection and sterilization effect, but also can oxidize and remove difficult-to-biodegradable pollutants in water. However, if ozone is used alone to mineralize difficult-to-biodegradab...
