Description
Technical field
A kind of combined ecological floating bed device relates to a kind of combined ecological floating bed device that is used for dystrophication water body in-situ purifying treatment.Belong to water-treatment technology field.
Background technology
In recent years, along with social economy's fast development, the water pollutant quantity discharged increases year by year, natural waters such as the river course of China, lake and reservoir are subjected to pollution in various degree, and the gesture that aggravation is arranged, the people's life and health in serious threat, and the prevention and cure of pollution of natural water have become the significant problem that needs to be resolved hurrily.Biological floating bed technology has become in-situ treatment technology commonly used in polluted water body restoration of the ecosystem of lake, river and the purifying treatment.What occur the earliest is biological floating bed often just by certain fixed form planting aquatic plants on the water, utilize the absorption and the plant-microorganism cogeneration system of root system of plant to purify water, but limited because of floating bed plant and the microbe population that adheres to, cause the effects of purification quality of the type floating bed not high.For improving biological floating bed biopurification effect, progressively to have developed in lower floor the fixedly floating bed of 3-D filler layer has been set, the formation of carrier biofilm can improve biological floating bed microbe population.At present, the filler of the biological floating bed employing of the type mostly is soft-filler and elastic solid filler, because these fillers are all used development at sewage work, do not consider the geographical features of natural water (as river course and Hu Ku) and hydrological characteristics etc., it is in the natural water purification applications, existence installation and replacing are difficult, flow resistance is big, be subject to deficiencies such as water impact destruction, easy knotting, have limited its practical application in contaminated natural water purifying treatment greatly.
At present biological floating bed fixed method is mainly contained rope method and support method.The rope method is meant with rope and is fixed in bank or the water biological floating bed, but there is certain defective in this method: under the situation of wave disturbance and change of level, single floating bed buoyant scope is inconsistent, causes the floating bed overall alignment mixed and disorderly, influences river course view and shipping.The support method can finely overcome the biological floating bed influence that is subjected to stormy waves, but still has the deficiency of difficulty being installed and influencing the safety of shipping.
Summary of the invention
The objective of the invention is to disclose a kind of be used for natural water (river course, Hu Ku) the original position purifying treatment is combined ecological floating bed, it is not enough and install and fix the above-mentioned defective of being brought to be intended to overcome existing biological floating bed effects of purification quality.This is combined ecological floating bed have simple in structure, installation administration convenient, effects of purification quality is good, the anti-current-rush ability is strong, can and not influence characteristics such as river course shipping safety with the change of level automatic lifting.
Above-mentioned purpose is achieved through the following technical solutions: by hard fixed link and two rotating shafts the buoyancy aid embankment of vertical is fixed, buoyancy aid can be with the fluctuation of water level free VTOL (vertical take off and landing), under the buoyancy aid gauze bio-packing is installed, to increase microbial biomass, collocation is planted and is implanted with waterplant such as yellow flag, Scirpus tabernaemontani, Canna generalis Bailey, water money and Caulis Miscanthis floriduli in the floating bed mainboard implantation hole.Concrete structure is as follows:
Form by anchoring pole, fixed rotating shaft, union lever, fixed link, buoyancy aid, biological net filler and waterplant, fixed two fixed links in buoyancy aid top, fixed link one end flexibly connects by an end of fixed rotating shaft and union lever, the other end of union lever flexibly connects by an end of fixed rotating shaft and anchoring pole, and the anchoring pole the other end is fixedlyed connected with revetment; Buoyancy aid is formed by fixedly connecting by floating bed framework and floating bed mainboard, and the bed surface of floating bed mainboard is evenly offered implantation hole, planting aquatic plants in the implantation hole; Two side bottoms of floating bed framework are welded with link, insert the installation plug at biological net filler bracing frame two ends in the link, make fixed biologically net filler be fixed on buoyancy aid below; Four basket framves of biological net filler bracing frame are provided with through hole, are provided with the fixed rope around the biological net filler, and rope penetrates in the through hole and bundlees, and biological net filler is fixed on the biological net filler bracing frame.
Described fixed link one end flexibly connects by an end of fixed rotating shaft and union lever, the other end of union lever by the end flexible connection of fixed rotating shaft and anchoring pole is, tongue-and-groove is respectively offered on anchoring pole and fixed link top, have hole A and C on the tongue-and-groove, the two ends of union lever are equipped with the tenon with the tongue-and-groove coupling, all have hole B on the tenon, during installation, the tenon at the two ends of union lever and anchoring pole and the vertical tongue-and-groove of fixed link are aligned insertion, and hole A and C on the tongue-and-groove are alignd with the hole B of tenon respectively, insert fixed rotating shaft then, in the retaining hole of fixed rotating shaft, insert fixing can the realization of rivet and connect.
Described waterplant is yellow flag, Scirpus tabernaemontani, Canna generalis Bailey, water money or Caulis Miscanthis floriduli, can single variety plantation, perhaps two kinds or above different collocation plantation.
With existing biological floating bed comparing, the present invention has the following advantages:
1. the combination of biological floating bed and gauze bio-packing has increased biological floating bed microbe population greatly, has improved N, P in the water body and organic removal ability;
2. biological floating bedly fix by two rotating shaft embankment of vertical, when water level changed, floating bed can be in the changing conditions automatic lifting of vertical direction with water level, and keep proper alignment on the water surface of river course bank;
3. characteristics such as the biological net filler of Cai Yonging has the specific surface area height, and carrier surface forming biofilm property is good, and the independent support frame that is provided with have been avoided winding, knotting and obstruction between different biological nets;
4. biological net filler can be according to using depth of water situation adjustment height, and it is convenient to install and change;
5. biological net filler can freely swing with the variation of current, can keep certain angle of inclination when being subjected to the impact of current, when increasing mass transfer, has effectively reduced the flow resistance of filler, and the anti-current-rush ability is strong;
6. this combined ecological floating bed device has further been strengthened N, P and organic matter removal performance when having good landscape effect, is very suitable for the original position purifying treatment of nature river course, Hu Ku and landscape water body.
