Description
Technical field
The present invention relates to technical field of sewage purification, be specifically related to a kind of photochemical catalysis tank for sewage disposal.
Background technology
The effect of photochemical catalysis in water treatment has obtained the confirmation of great many of experiments now, and in some occasion, has had the application of case.The method of now general photocatalysis treatment sewage has two kinds, and a kind of method is that photocatalyst is coated fixing surface, and thin layer liquid stream through its surface, and coordinates catalysis light source irradiation, thus completes photochemical catalysis, arrives the effect of degraded COD.But due to the area constraints of fixed surface, so the contact surface of photocatalyst and liquid is limited, catalytic effect is undesirable, and adopts thin layer to flow through, and limits its sewage treatment capacity.Another kind method is mixed in water powder or granular photocatalyst, although effectively can increase the contact area of catalyzer and sewage, the recovery of photocatalyst and recycle are quite difficult.
Summary of the invention
For the problems referred to above, the invention provides a kind of photochemical catalysis tank for sewage disposal, its catalytic efficiency is high, can be used in the sewage disposal occasion of big yield, and later collection process is convenient.
Its technical scheme is such, and it comprises pond body, it is characterized in that: it also comprises photochemical catalysis combined stuffing, ultraviolet lamp and airing system; Be placed with photochemical catalysis combined stuffing equably along depth direction in the body of described pond and be provided with ultraviolet lamp, often organize photochemical catalysis combined stuffing and comprise back shaft and some rotating disks, the two side that the two ends of described back shaft are individually fixed in pond body be arranged in parallel with pond body diapire, described rotating disk is supported on described back shaft by the bearing fit that its central hole is arranged, the side of described rotating disk is provided with radially protruding blade, the outer end of described blade is fixed with polypropylene fibre, and surface and the described polypropylene fibre surface coated of described rotating disk have photocatalyst layer; Described airing system comprises air compressor machine and the valve by pipeline and air compressor machine UNICOM, and described valve is fixed on described pond body diapire, and along described back shaft axial arranging.
Further, the width ratio scope of the length of described polypropylene fibre and the length of blade, the annular body of rotating disk is (6 ~ 8): (3 ~ 2): 1.
Further, the photocatalyst layer of described disc surfaces is plucking shape.
Further, described photocatalyst layer is nano-TiO
2layer.
Adopt the photochemical catalysis tank for sewage disposal of the present invention, photochemical catalysis combined stuffing is supported in pond by back shaft, be coated with the polypropylene fibre of photocatalyst, rotating disk is suspended in sewage, by ultraviolet lamp catalysis, the pollution substance in degradation of sewage, this photochemical catalysis filler is compared with thin layer photochemical catalysis, its photocatalyst and waste water area large, photocatalysis efficiency is high, can be used in the sewage disposal occasion of big yield, and later collection process is convenient; Airing system can urge blade, makes dial rotation, thus carry fluid motion, impel the organism flowing in sewage and UV-light, TiO
2water and oxygen excite hydroxyl radical free radical and the Superoxide anion free radical reaction of generation, improve photocatalysis efficiency further.
