Embodiment Construction
[0009] see figure 1 , the treatment device of the present invention includes an ozone preparation room 1, an ozone contact pool 2, a lifting pump room 3 and a biological activated carbon filter pool 4, and several deflectors that are comb-shaped and inserted up and down are arranged in the ozone contact pool 2 8 (the purpose is to increase the flow process of sewage, thereby prolonging the contact time of sewage and ozone), respectively be provided with ozone sprinkler 7 between adjacent deflectors 8, be respectively provided with sewage inlet at both ends of this ozone contact pool 2 Water port 6 and ozone contact pool outlet 9. The ozone preparation room 1 is respectively connected with each of the ozone nozzles 7 through the ozone pipeline 5, and the ozone contact pool outlet 9 passes through the lift pump 10 in the lift pump room 3 and the water distribution device inlet 12 of the biological activated carbon filter 4. (with valve) connection.

The invention discloses an ozone-biological activated carbon water purification method and device. The method comprises the following steps of: firstly, pumping sewage of slightly polluted rivers and lakes into an ozonation contact reactor; contacting and mixing the sewage with an ozone component released by an ozone spray nozzle in the ozonation contact reactor; pumping the sewage mixed with ozone into a biological activated carbon filter; and adsorbing and purifying pollutants in the sewage by using a biological activated carbon filtering layer and then discharging. The invention has the advantages that: an activated carbon physical-chemical adsorption device, an ozone chemical oxidation device and a biological oxidative degradation device are integrated, and non-degradable organic matters in the sewage are oxidized into degradable organic matters by using ozone and then enter the biological activated carbon filter for further removal of the organic matters. The ozone-biological activated carbon water purification method and device are suitable for treating polluted rivers and slightly polluted rivers and lakes and can be used for constructing a high-quality regenerated water plant. The ozone-biological activated carbon water purification device has a simple structure and is convenient to operate.
Description
technical field [0001] The invention relates to an ozone-biological activated carbon water purification method and device, which are suitable for the treatment of polluted river water and slightly polluted rivers and lakes, and can also be used for the construction of high-quality reclaimed water plants. Background technique [0002] There are various forms of pollutants (dissolved, suspended, colloidal substances, microorganisms, etc.) in polluted rivers, slightly polluted rivers and lakes. The prior art generally uses activated carbon for purification, because the pollutants in the above water are quickly adsorbed on The surface of activated carbon needs to be washed and activated frequently to maintain the purification effect of activated carbon, which will greatly reduce the treatment efficiency and increase the treatment cost. Need to be equipped with the flushing device in addition, the structure is complicated, and the operation is loaded down with trivial details. ...
