2, plant decomposition pond is set, for current wetland supplements organic carbon source, facilitates denitrification in current wetland, further increase the denitrification effect of wetland.
Accompanying drawing explanation
Fig. 1 is the structural representation of step artificial swamp advanced denitrification processing apparatus of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail, but this embodiment should not be construed as limitation of the present invention.
See Fig. 1, step artificial swamp advanced denitrification processing apparatus of the present invention, comprise settling pit 1, vertical-flow wetland 5 and current wetland 9, also comprise the one-level inverse u shape pipe equalizing tank 4 and secondary inverse u shape pipe equalizing tank 8 that are built-in with inverse u shape pipe 3 respectively, described settling pit 1, one-level inverse u shape pipe equalizing tank 4, vertical-flow wetland 5, secondary inverse u shape pipe equalizing tank 8 is arranged in order with current wetland 9 and is connected, described settling pit 1, one-level inverse u shape pipe equalizing tank 4, vertical-flow wetland 5, the water outlet of secondary inverse u shape pipe equalizing tank 8 and current wetland 9 is arranged from high to low.The water outlet of described settling pit 1 is provided with ball valve 2.
Described secondary inverse u shape pipe equalizing tank 8 side is provided with the plant decomposition pond 6 that water outlet is connected with secondary inverse u shape pipe equalizing tank 8, and the water outlet in described plant decomposition pond 6 is higher than the water outlet of secondary inverse u shape pipe equalizing tank 8.Described plant decomposition pond 6 is between vertical-flow wetland 5 and secondary inverse u shape pipe equalizing tank 8.The water outlet in described plant decomposition pond 6 is higher than the water outlet of vertical-flow wetland 5.The water outlet in described plant decomposition pond 6 is provided with check valve 7.
Principle of work of the present invention is as follows: before vertical-flow wetland 5 and current wetland 9, all set up inverse u shape pipe equalizing tank, water is entered by the pulsed of inverse u shape pipe equalizing tank, automatically the intermittent type realizing wetland enters water, promote that oxygenation/anoxic process appears in wetland circulation, improve the nitrification and denitrification effect of wetland.And the organic carbon that decomposition obtains by plant decomposition pond is set adds in current wetland 9 by secondary inverse u shape pipe equalizing tank 8, improve the denitrification of current wetland 9.The water outlet of described settling pit 1, one-level inverse u shape pipe equalizing tank 4, vertical-flow wetland 5, plant decomposition pond 6, secondary inverse u shape pipe equalizing tank 8 and current wetland 9 is arranged according to physical features from high to low, is beneficial to water automatic flowing under gravity.
Working process of the present invention is as follows: first sewage flow into overflow well (not shown) by pipeline, settling pit 1 is entered again via overflow well, after part large particulate matter is removed in the gravitational settling effect of settling pit 1, one-level inverse u shape pipe equalizing tank 4 is flowed to again by settling pit 1, one-way cock 2 is provided with between settling pit 1 and one-level inverse u shape pipe equalizing tank 4, can the water outlet of Artificial Control settling pit 1 and the water inlet of one-level inverse u shape pipe equalizing tank 4, due to the pulse syphonic effect of the inverse u shape pipe 3 in one-level inverse u shape pipe equalizing tank 4, sewage is made to realize automatic feeding water, and can automatically rapidly flow toward next processing unit-vertical-flow wetland 5 when reaching certain liquid height, so just reach the object of automatic feeding water, and aerobic process repeatedly, enhance the nitrification of vertical-flow wetland 5, even if the ammonium salt in sewage is oxidized to nitrate.The water that vertical-flow wetland 5 flows out enters current wetland 9 by secondary inverse u shape pipe equalizing tank 8 again, realizes the circulation anaerobic/aerobic process of current wetland 9, thus improves denitrification efficiency, and the nitrate namely in sewage is reduced to nitrogen.And between vertical-flow wetland 5 and secondary inverse u shape pipe equalizing tank 8, set up plant decomposition pond 6, between plant decomposition pond and secondary inverse u shape pipe equalizing tank 8, a check valve 7 established by pipeline, vertical-flow wetland 5 water outlet can be avoided to enter plant decomposition pond 6, simultaneously, plant decomposition, the water outlet of 6 is higher than the water outlet of vertical-flow wetland 5, and the aqueous reflux that goes out that it also avoid plant decomposition pond 6 enters vertical-flow wetland 5, because the aquifer yield in plant decomposition pond 6 is very little.Harvested wetland plant is put into plant decomposition pond 6 to decompose, discharge carbonaceous organic material.The water outlet of these organism and vertical-flow wetland 5 mixes in secondary inverse u shape pipe equalizing tank 8, and by secondary inverse u shape pipe equalizing tank 8, these organism are added to current wetland 9, facilitate denitrification in current wetland 9, thus reach the object removing nitrogen in sewage further.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
The content be not described in detail in this specification sheets belongs to the known prior art of professional and technical personnel in the field.
