Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
The complex ecological bed waste water treatment system of the artificial intensified denitrification and dephosphorization of the present invention, structure is as it is shown in figure 1, include using water
Filter tank 1, composite ecological bed 3 and the catalyzing disinfection district 4 that pipe is sequentially connected with, filter tank 1 be provided with near the side of water inlet with
The filter screen 2 that bottom land is vertical, composite ecological bed (3) include the 303, second filtering area, inhalant region the 301, first filtering area being sequentially connected with
304, the 3rd filtering area 305 and exhalant region 306, described inhalant region 301 is connected by water pipe with filter tank 1, described exhalant region 306
Connecting with catalyzing disinfection district 4, be provided with the first overflow wall 302 in described inhalant region 301, described first overflow wall 302 vertically sets
Put the centre position bottom inhalant region 301, in described exhalant region 306, be provided with the second overflow wall 307, described second overflow wall
307 are vertically arranged in the centre position bottom exhalant region 307.
First filtering area 303 is internal is filled with cobblestone, a diameter of 3cm～6cm of described single cobblestone.
Second filtering area 304 is internal is filled with slag.
3rd filtering area 305 is internal is filled with rubble, and the particle diameter of described single rubble is 1cm～3cm.
The bottom in catalyzing disinfection district 4 is provided with tank 7, and the uviol lamp of more than 2 is installed at the top in described catalyzing disinfection district 4
Pipe 5, the side of described catalyzing disinfection district 4 tank more than 7 hangs photocatalysis board 6.
Photocatalysis board 6 surface scribbles coating of titanium dioxide.
The work process of the complex ecological bed waste water treatment system of the artificial intensified denitrification and dephosphorization of the present invention is that sewage first passes through
Filter tank 1, by oarse-grained magazins' layout out, then purifies in composite ecological bed 3, and concrete purification process is: dirty
Water enters in bed body by the inhalant region 301 of composite ecological bed 3, and the first overflow wall 302 can slow down the flow velocity of water, enters bed body
Interior sewage flows slowly into the first filtering area 303, and the cobblestone in the first filtering area 303 slows down the flow velocity of sewage, causes one
The pollutant sedimentation divided, reaches the purpose of preliminary purification.
Sewage through preliminary purification flows into the second filtering area 304 that position is relatively low under the effect of self gravitation, and second
The organic pollution such as the nitrogen in slag absorption effluent in filtering area 304 and phosphorus, reaches the purpose of double purification.
Sewage through double purification flows into the 3rd filtering area 305 that position is lower under the effect of self gravitation, and the 3rd
Rubble in filtering area 305 filters out contaminant particle more small in sewage further, is that sewage purification becomes water purification.
Water purification flows into catalyzing disinfection district 4, and the coating of titanium dioxide on photocatalysis board 6 surface, under the irradiation of ultraviolet lamp tube 5, produces
Liveliness proof material, is greatly improved photocatalysis rate.The harmful gas of residual, organic pollution in sewage are divided with the fastest speed
Solve, make water quality further purify.
Water quality after purification can be not only used for agricultural pouring, moreover it is possible to be used for wash dish, have a bath wait secondary utilization, effectively save
Save water resource.
