Along with the increasingly stringent of national requirements for environmental protection, the most commonly used sewage treatment process is extremely difficult to discharge standard, because of
The advanced treating of this sewage is particularly important.Ozonation technology is a kind of feasible further treatment technique, but it is higher
Investment and operating cost limit its application in advanced treatment of wastewater.It is smelly that the investment of ozonation technology essentially consists in it
Oxygen generating equipment and ozone reactor, the expense of pure oxygen when its operating cost is mainly the electricity charge and uses pure oxygen to occur.Due to smelly
The oxygen dissolubility in water at normal temperatures and pressures is relatively low, and the reaction rate causing ozone and Organic substance in water is relatively slow, therefore
When using conventional ozone reactor to carry out advanced treatment of wastewater, need longer hydraulic detention time.Again due to the corruption of ozone
Erosion property so that ozone reactor needs use high-quality rustless steel or equipment is carried out specific preservative treatment.In sewage disposal
In, owing to water pollutant content is of a relatively high, typically require employing pure oxygen aeration to obtain higher ozone concentration, pure
The expense of oxygen generation and equipment also further increase the cost of ozonation technology.And there is prepared ozone concentration in pure oxygen
Generally only between 7%～10%, this makes substantial amounts of pure oxygen be wasted.Therefore smelly to reduce by high efficiency ozone reaction
Oxygen reactor volume, reduces operating cost become solution ozonation technology application by improving ozone and pure oxygen utilization ratio
The key of problem.The granular filler of BAF built-in raising specific surface area is as the carrier of biofilm development；At filtrate
Layer bottom carries out aeration provides oxygen source for microorganism, make the organic pollution in sewage under the biomembranous effect of filling surface
To degraded；Filler simultaneously works as physical filtering effect, and BAF is frequently as sewage water advanced treatment apparatus.Individually use
BAF carries out advanced treating, but the removal effect for hardly degraded organic substance is limited, and before BAF
Carry out ozone Oxidation Treatment, part hardly degraded organic substance can be decomposed, improve Biodegradability of Wastewater, thus it is raw to improve aeration
The treatment effect in thing filter tank.
