Description

Tidal river is with biological floating bed
Technical field
The utility model relates to use in a kind of river biological floating bed, especially is applicable to biological floating bed in the tidal river.
Background technology
Tidal river is because itself special hydraulic performance makes its water surrounding have special nature: the part pollution substance in the river is in to-and-fro movement in the district of the network of waterways under the effect of morning and evening tides, can not be discharged into Jiang Haizhong, become the pollution water body, can only rely on the self-purification capacity in river itself to be cut down, because land-sourced pollutant fails to be handled preferably, pollute thing and continue to enter the river, in case pollution substance surpasses the self-purification capacity in river, can make pollution water body scope increasing, simultaneously under the effect of disadvantageous hydrodynamic condition, in zone, the whole network of waterways, carry out crossed contamination, cause whole tidal river barrier to be polluted simultaneously to some extent, the water surrounding in whole basin is seriously influenced.
Through biological floating bed denitrogenation Study on Mechanism is found that prevailing on the removal mechanisms at work of nitrogen is the Degradation of microorganism.The present removal mechanism of relevant nitrogen, from reaction process, the more consistent understanding of academia be ammonification and compound nitrated-denitrification, and microorganism nitrated-denitrification plays a major role in the removal of nitrogen.Wherein, denitrification is the most effective denitrogenation approach in the system.So the quantity that improves system's denitrifying bacteria in tidal river as far as possible is the key that further improves efficiencies of nitrogen removal to strengthen denitrification.Existing biological floating bed technology governance sealing polluted-water is comparatively commonly used, but not ideal enough to the treatment effect of tidal river.Because, on the one hand, current are stronger to washing away of microorganism in the tidal river, and the nitrogen cycle microbe population relative with kind less (especially denitrifying bacterium) in characteristic the makes water such as the residence time is relatively short, can't finish effective degraded and absorption to nitrogen; On the other hand, there is not the specialized structure that can introduce immobilized microorganism in existing biological floating bed bed body, most of biological floating bedly just on the floating bed material, improve to some extent, and the quantity of the denitrifying bacteria in the floating bed system can not get guaranteeing, so it is, particularly very limited to the removal effect of nitrogen in the tidal river to the effect of nitrogen in the further removal water body.
Summary of the invention
The purpose of this utility model provides a kind of tidal river with biological floating bed, can introduce immobilized microorganism in biological floating bed adheres to, the better collaborative denitrogenation between performance microorganism and the floating bed plant strengthens handling the effect that nitrogen is removed in the tidal river.
Technical solution of the present utility model is: a kind of tidal river is with biological floating bed, interconnect by the floating bed unit and to form, each floating bed unit comprises the kickboard which is provided with waterplant, and the unitary described kickboard of each floating bed below hangs and is provided with the gauze that internal package has the biologic packing material that contains denitrifying bacteria.
But planting aquatic plants on the unitary kickboard of floating bed, parcel contains the biologic packing material of denitrifying bacteria in the gauze that its below hangs, can increase the denitrifying bacteria biomass at the waterplant root area, improve collaborative denitrogenation between microorganism and the waterplant, wrap up this biologic packing material by gauze, can effectively prevent washing away of current, strengthen the effect that nitrogen is removed.
Described gauze is hung vertically in described kickboard below, can reduce the resistance of underwater portion, slows down the sluicing of waterplant root system part, helps improving partial microbial biomass, strengthens the nitrogen processing efficiency.
Described gauze horizontally suspends below described kickboard, is applicable to more shallow waters.
It also be provided with can be in the river localized fixed link, be arranged with the sliding metal ring on this fixed link, each described floating bed unit is connected on the metal ring by wire, during change of level, the floating bed unit can move up and down realization at fixed link by metal ring to be changed with the variation of water level, the floating bed unit also is limited in can not influencing the river normal function in the fixed zone simultaneously.
It also is provided with aerating apparatus, described aerating apparatus is the aeration tube that is arranged on described gauze below, sheathed sliding shoe on the described fixed link, described aeration tube is connected on the described sliding shoe by wire, increase oxygen content in the waters by aeration, further strengthen collaborative denitrogenation intensity between microorganism and the waterplant, improve the efficient of floating bed system purification, by sliding shoe moving up and down on fixed link, the convenient position of aeration tube in water of regulating helps control and adapts to change of level.
Described aerating apparatus is the surface aeration equipment that is arranged between the described floating bed unit, sheathed sliding shoe on the described fixed link, and described surface aeration equipment is connected on the described sliding shoe by wire.Surface aeration equipment is applicable to more shallow waters, can improve oxygen level equally, strengthens denitrogenation intensity, improves purification efficiency, also helps control and adapts to change of level.
The utility model has the advantages that: realized that microorganism and waterplant work in coordination with denitrogenation, significantly improved system's denitrogenation purification efficiency, solved in the tidal river because the pollution problem that change of level is big, pollutent back and forth transmits cross influence is simple in structure, working cost is low, and treatment effect is good.
