Detailed Description
The invention will be further described with reference to the drawings and detailed description.
As shown in fig. 1-3, the FBR biological bed 10 of the present invention is disposed on the shore of the water body 1, and divides the water body into an FBR biological bed 10 area and a clear water area 11, as shown in fig. 2 and 3, one FBR biological bed 10 may be disposed in the water body 1, or a plurality of FBR biological beds may be disposed in a fragmentation manner; the FBR biological bed 10 is formed by enclosing a retaining wall 101, a water body revetment 102 and a water body bottom 103 which are arranged on the bank side; and the upper part of the FBR biological bed 10 is connected with a clean water zone 11; the FBR biological bed 10 is filled with a biological filter material 104, and a water collecting pipeline 105 is arranged at the bottom or lower part of the biological filter material 104; algae in the clear water area can flow to the FBR biological bed along with the horizontal flow of water flow and vertically pass through the FBR biological bed downwards, and part of algae are phagocytized by protozoans feeding algae on a biological film in the filter bed, so that the running period and time of a circulating pump can be controlled to control the explosion of the algae; meanwhile, excessive phagocytosis of algae can be avoided by reducing the running time, a certain amount of algae can be provided for water in a clear water area, so that the FBR biological bed is ensured to be kept in a higher dissolved oxygen range, and good biological film formation is facilitated;
at least one water well 106 is arranged in the FBR biological bed; the water collecting pipeline 105 is communicated with the water well 106; at least one circulating water pump 107 is arranged in the water well 106, and the circulating water pump 107 is connected with a return pipeline 108; the return pipeline 108 extends into the clear water zone 11, and at least one jet orifice 1081 is arranged at the bottom of the clear water zone and/or at least one drop wave making port 108 is arranged at the upper part of the clear water zone in the return pipeline 108, so that when the water discharged by the circulating pump flows back to the water body through the drop wave making port, the fluctuation of the water surface can be promoted, and the natural reoxygenation of the water body surface can be increased; the improvement of the integral dissolved oxygen of the water body further promotes the operation effect of the biological membrane in the FBR biological filter bed.
The FBR biological bed is abbreviated as a fixed biological filter bed, wherein F is abbreviated as filter and fixed, B-biology and bed are abbreviated as reactor, and the biological bed adopts the form of the biological filter bed, microorganisms are fixed in the filter bed, and the filter bed can provide functions of water quality filtration, anaerobic reaction, aerobic reaction and the like, so the filter bed is called the fixed biological filter bed, and English words are abbreviated as the FBR biological bed.
The FBR biological bed provided by the invention has the following advantages:
1) Surface water or shallow groundwater with pollutants is diluted rapidly after entering a clear water area, and part of the pollutants can be decomposed and adsorbed by algae in the water; part of the pollution is decomposed by microorganisms in a biological film on the upper part of the biological film after entering the biological bed of the FBR along with water flow, and clean water is discharged from the bottom of the biological bed of the FBR;
2) The water discharged from the circulating pump flows back to the water body through the water bottom jet orifice, so that the exchange of upper and lower water bodies can be promoted, the water with higher surface dissolved oxygen can be effectively exchanged to the lower layer, the aerobic treatment of the bottom sludge is promoted, the microorganism types of the bottom sludge are enriched, and the total storage amount of the bottom sludge to phosphorus is increased;
3) The FBR biological bed is arranged in the existing water body, and the retaining wall and the bottom structure of the existing water body are fully utilized, so that the problem of difficulty in ecological engineering land sign can be effectively solved, and meanwhile, the construction is low in cost and convenient.
4) The lift of the circulating water pump is only 1.0-2.0m, so that the consumption of electric energy is greatly reduced; meanwhile, the water pump is effectively protected by water pumping from the bottom of the biological bed, so that long-term stable operation of the biological bed is ensured;
5) When the total amount of pollutants discharged into the water body is large, water can be directly carried out from the upper part of the FBR biological bed, and a good treatment effect can be achieved;
6) The FBR biological bed can adopt more flexible fragmentation arrangement, and the application range of the technology is greatly improved.
Further, the retaining wall 101 is formed by bricking or stone masonry, and the height of the retaining wall is lower than the water level of the clean water area or the water inlet of the FBR biological bed is lower than the water level; thus, the FBR biological bed can be enabled to enter water from the upper part, so that suspended matters (inorganic particles) in the water body can be ensured to be deposited most advantageously at any time, and the blockage of the inorganic particles can be effectively relieved; meanwhile, the water inlet area has a certain water layer thickness, so that floaters can be prevented from entering the biological bed of the FBR to cause blockage.
Further, the filter material in the FBR biological bed is preferably vesuvianite or gravel or other biological fillers with high porosity; the biological filter material has higher porosity, is beneficial to microorganism implantation and formation of a biological film, and simultaneously, the types and the quantity of microorganisms at the upper part of the filter bed are automatically propagated and adjusted according to the concentration and the types of pollutants in a clear water area; in addition, different kinds of microorganisms can be implanted using microorganism immobilization techniques as desired to promote formation of dominant colonies.
Further, if the bottom of the FBR biological bed 10 is too soft, a sand-stone exchanging layer 109 may be laid on the bottom of the FBR biological bed, and a geomembrane 110 may be laid on the sand-stone exchanging layer 109 to prevent the sludge at the bottom from entering the FBR biological bed 10.
Further, the circulating water pump 107 provides kinetic energy by solar energy, wind energy or conventional power.
Further, aquatic plants 111 such as dovetails, calamus, flowers of restitution, etc. may be planted on the FBR bio-bed 10; on the one hand, the landscape effect can be improved, meanwhile, the biodiversity of the relatively closed water body can be improved, and the root system of the aquatic plant with developed ventilation tissue can provide partial dissolved oxygen for the FBR pool.
Preferably, low-density ornamental fish or economic fish are cultivated in the clear water region 11; the ecological stability of the water body is more facilitated.
The FBR biological bed can be used for constructing an ecological system of low-algae and low-turbidity water or for ecological restoration of polluted water.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
