| 英文摘要: |
| Ozone disinfection is one of the key technologies in water treatment of industrial aquaculture. In order to
improve the efficiency of ozone mixing, a multi-layer ozone mixing device was researched and developed based on the
theory of ozone dissolution, and effects of different types of packing, vapor liquid ratio and packing height on ozone
dissolution efficiency were studied. The results showed that using pall ring as filler, reducing the vapor liquid ratio within a
certain scope and increasing the packing height would improve efficiency of ozone dissolution. When packing height was
0.7 m, water flow was 6 m3/h and ozone gas flow rate was 0.1 m3/h, which meant that vapor liquid ratio was 1/60, water
treatment capacity was 190 m3/h窑m2, ozone dissolution efficiency reached 78%. The device has the advantages of simple
structure, small volume, easy installation and maintenance, high mixing efficiency and no blockage, can be optimized for
the water treatment process and system of recirculating aquaculture, and puts forward a feasible way for good mixing
efficiency and economic efficiency. |
