Detailed Description
The present invention is further illustrated below in conjunction with specific embodiments, it being understood that these embodiments are meant to be illustrative of the invention only and not limiting the scope of the invention, and that modifications of the invention, which are equivalent to those skilled in the art to which the invention pertains, will fall within the scope of the invention as defined in the claims appended hereto.
As shown in fig. 1, the ecological purification treatment gallery for water quality of river and lake life sewage outlet comprises an inner layer purification tank 2 and an outer layer purification tank 3; wherein:
the outer contour of the inner purifying tank 2 is of a rectangular structure with one surface open and three surfaces closed, and comprises two long sides and one short side; the short side is used as the water outlet end of the inner layer purifying tank 2; the water inlet end of the inner layer purifying tank is communicated with a river and lake living sewage outlet 1; the long side 4 of the inner layer purifying tank is arranged along the water flow direction discharged by the river and lake life sewage outlet 1, is made of a light long rod, has the length range of 100-200 m, is fixedly connected with a plurality of plastic floating blocks 8 for providing buoyancy for the inner layer purifying tank 2, and one end of each plastic floating block is vertically and fixedly connected with the bank side outside the river and lake life sewage outlet 1; the long sides 4 of the two inner purifying tanks are respectively positioned on the side walls of the river and lake living sewage discharge outlet 1; the short side 5 of the inner purifying tank is vertical to the long side 4 of the inner purifying tank, and is made of a light long rod, and the length of the light long rod is not lower than the diameter of the river and lake life sewage outlet 1; two ends are respectively and vertically fixedly connected with the other ends of the long sides 4 of the two inner-layer purifying tanks, which are far away from the bank; the long side 4 of the inner purifying tank and the short side 5 of the inner purifying tank are fixedly provided with a dense mesh net 9 for primary filtering of sewage discharged from the river and lake domestic sewage discharge outlet 1, and the dense mesh net 9 on the long side 4 of the inner purifying tank is in seamless connection with the dense mesh net 9 on the short side 5 of the inner purifying tank; as shown in fig. 3, the dense mesh net 9 on the long side 4 of the inner purifying tank and the dense mesh net 9 on the short side 5 of the inner purifying tank are connected with the tank bottom in a seamless manner.
It should be noted that the water-supply device is arranged along the water-supply line of the river and the lake, is sleeved on the living sewage discharge outlet 1 of the river and the lake, and naturally discharges the sewage discharged from the living sewage discharge outlet 1 of the river and the lake into the river and the lake after purifying.
It should be further noted that, in this embodiment, the length of the long side 4 of the inner purifying tank is 150m. The length range of 100m to 200m is one of the very important data of the present application, in the sense that the sewage reaching the short side 5 of the inner purification tank just meets the discharge standard at the lowest cost.
The length of the long side 4 of the inner purifying tank needs to be set according to the diameter and the discharge capacity of the corresponding river and lake life sewage outlet 1; the river and lake domestic sewage outlet 1 is calculated according to the national standard, so that the maximum sewage outlet is only 200m, but cannot be lower than 100m, otherwise, the sewage outlet cannot reach the emission standard.
In this embodiment, the mesh size of the dense mesh 9 is 0.005m×0.005m.
In the present embodiment, the light long rods are phyllostachys pubescens with the diameter ranging from 0.03m to 0.05 m.
The inner purifying pond 2 is also internally provided with a plurality of first ecological floating blocks 11 for planting purifying plants 16 and a plurality of first fixing rods 12 for fixing the first ecological floating blocks 11; the first ecological floating block 11 is made of light plastic, and a planting groove is distributed in the middle; the bottom of the planting groove is provided with a through hole penetrating through the first ecological floating block 11 and used for conveniently purifying the root system 17 of the plant 16 to extend into water; the root system 17 of the purified plant 16 naturally drops and floats in the water; the first ecological floating block 11 is connected in series with the first fixed rod 12; the length of the first fixing rod 12 corresponds to the length of the long side 4 of the inner purifying tank, one end of the first fixing rod is fixedly connected with the bank outside the river and lake living sewage outlet 1, and the other end of the first fixing rod is vertically and fixedly connected with the short side 5 of the inner purifying tank.
In this embodiment, the first ecological floating blocks 11 are equidistantly distributed on the first fixing rod 12; the distance between two adjacent first ecological floating blocks 11 ranges from 1.0m to 1.5m.
In this embodiment, the distance between two adjacent first fixing rods 12 is 1.0 m-1.5 m.
It should be further noted that, in this embodiment, the distance between two adjacent first ecological floating blocks 11 is preferably 1.0m; the distance range of the two adjacent first ecological floating blocks 11 is 1.0 m-1.5 m, which is also one of important data in the application; the significance is that the water quality reaches the standard when the least planted purified plants 16 are used for realizing the seepage from the short side 5 of the inner purifying tank; while a pitch of 1.5m is added redundancy for the purpose of greater security.
In this particular embodiment, the decontamination plants 16 involved are divided into two categories: aquatic plants and submerged plants; wherein: the aquatic plant comprises flos Nelumbinis, herba Alii Fistulosi and rhizoma Phragmitis, and the submerged plant comprises Sargassum horneri, herba Ixeritis Sonchifoliae and herba Potamogetis crispa.
The reason for selecting the plants is that the root system 17 is developed, the dirt adsorption capacity is very strong, the plants can adapt to the relatively polluted water quality, and the plants are several varieties with very good water purifying effect proved by practice and experiment for many years; the sewage is subject to physical filtration, interception, adsorption and conversion of the root system 17 group, and aquatic animals such as aquatic organisms, small insects, fishes and the like are caught and swallowed, the ecological system balance is maintained through organisms and food chains, and the natural purification treatment of the water quality of the sewage is promoted through the physical filtration, biological adsorption and chemical conversion of the root system 17 group, and the water quality is discharged into rivers and lakes after reaching the standard.
As shown in fig. 2, the outer contour of the outer purifying tank 3 is a rectangular structure with one surface open and three surfaces closed, and comprises two long sides and one short side; the short side is used as the water outlet end of the outer purifying tank 3; the long side 6 of the outer purifying tank is arranged along the water flow direction discharged by the river and lake life sewage outlet 1, is made of a light long rod, the length of the long side 6 corresponds to the length of the long side 4 of the inner purifying tank, the long side is 41-2 m away from the long side of the inner purifying tank, a plurality of plastic floating blocks 8 for providing buoyancy for the outer purifying tank 3 are fixedly connected on the long side, and one end of each plastic floating block is vertically and fixedly connected with the bank outside the water inlet end of the inner purifying tank; the long sides 6 of the two outer purifying tanks are respectively positioned on the side walls of the inner purifying tank 2; the short side 7 of the outer purifying tanks is vertical to the long side 6 of the outer purifying tanks, and is made of light long rods, and two ends of the light long rods are respectively and vertically fixedly connected with the other ends, far away from the bank sides, of the long sides 6 of the two outer purifying tanks; the long side 6 of the outer purifying pond and the short side 7 of the outer purifying pond are fixedly provided with geotextile nets 10 for preventing grass carp from entering the ecological purifying treatment gallery, and the geotextile nets 10 on the long side 6 of the outer purifying pond are in seamless connection with the geotextile nets 10 on the short side 7 of the outer purifying pond; as shown in fig. 4, the geotextile net 10 on the long side 6 of the outer purifying pond and the geotextile net 10 on the short side 7 of the outer purifying pond are seamlessly connected with the pond bottom; the geotextile net 10 on the short side 7 of the outer purifying pond is closely attached to one side of the dense mesh net 9 on the short side 5 of the inner purifying pond, which is far away from the river and lake life sewage drain 1.
It should be noted that, the geotextile net 10 used in this embodiment is a relatively impermeable geotextile net 10, which is used to prevent medium and large-sized grass carp from entering the outer purifying pond 3 and even the inner purifying pond 2, and gnawing the purified plant 16 root system 17 applied to purifying water quality and even the purified plant 16 itself.
A plurality of second ecological floating blocks 13 for planting purified plants 16 and a plurality of second fixing rods 14 for fixing the second ecological floating blocks 13 are also arranged in the space between the inner purifying tank 2 and the outer purifying tank 3; the second ecological floating block 13 is made of light plastic, and a planting groove is distributed in the middle; the bottom of the planting groove is provided with a through hole penetrating through the second ecological floating block 13 and used for conveniently purifying the root system 17 of the plant 16 to extend into water; the second ecological floating block 13 is connected in series with the second fixed rod 14; the length of the second fixing rod 14 corresponds to the length of the long side 4 of the inner purifying tank, one end of the second fixing rod is fixedly connected with the bank outside the water inlet end of the inner purifying tank, and the other end of the second fixing rod is vertically and fixedly connected with the short side 7 of the outer purifying tank.
In the specific embodiment, the second ecological floating blocks 13 are equidistantly distributed on the second fixing rod 14; the distance between two adjacent second ecological floating blocks 13 ranges from 0.3m to 0.5m.
It should be further noted that, in this embodiment, the distance between two adjacent second ecological floating blocks 13 is preferably 0.3m; the distance range between the two adjacent second ecological floating blocks 13 is 0.3 m-0.5 m, which is also one of important data in the application; the meaning is that the purified plants 16 planted at least are used for realizing that no matter which direction exudes from the outer purifying pond 3, the purified plants reach the standard water quality; whereas a spacing of 0.5m adds redundancy for the purpose of greater security.
In this embodiment, the distance between two adjacent second fixing rods 14 is in the range of 0.3m to 0.5m.
It should be noted that the density of the purified plants 16 in the inner purifying tank 2 is lower than that of the outer purifying tank 3, and the sewage in the inner purifying tank 2 is directly from the river and lake life sewage outlet 1, and the sewage is filtered by the plants with the concentration of 100-200 m and fully purified when reaching the short side 5 of the inner purifying tank although the concentration of the sewage is higher, so that the planting density of the purified plants 16 can be reduced, the construction and maintenance cost is reduced, and the sewage flows in the canal and is purified; the water in the outer purifying tank 3 is not sufficiently purified by the plant root system 17 in the inner purifying tank 2, and the pollution degree is still high, on the other hand, if the width of the outer purifying tank 3 is set by the same density of the planted purifying plants 16, the whole outer purifying tank 3 is too wide, and the economic cost and the maintenance cost are obviously unsuitable, so that the plant root system 17 with higher density is required for pollutant adsorption.
It should be further noted that, in theory, sewage should flow in the river and lake in a consistent way along the discharge direction, that is, only pass through the inner purifying pond 2, reach the discharge standard through the purification of the layer-by-layer purifying plants 16 therein, and finally permeate out from the short side 5 of the inner purifying pond through the dense mesh net 9, and be discharged into the river and lake; however, the dense mesh net 9 is still water permeable in practice, which cannot avoid that sewage seeps out from the dense mesh net 9 on two long sides of the inner purifying tank 2 in the process of flowing to the short plates of the inner purifying tank 2, and the sewage cannot enter the water body of the river and the lake because the sewage is not purified by enough purifying plants 16; for this reason, the present application provides an outer purification tank 3 for receiving contaminated overstandard sewage escaping from the inner purification tank 2, and then purifying it therein also with purifying plants 16, and finally reaching both the long side 6 of the outer purification tank and the short side 7 of the outer purification tank, which are both up to the standard dischargeable waters.
In the specific embodiment, an operation platform 15 for a person to stand is fixedly arranged on the long side 4 of the inner purifying tank and the long side 6 of the outer purifying tank; the operating platform 15 is made of lightweight plastic and has a width in the range of 1.0m to 2.0m.
The ecological purification treatment gallery of the application runs for about one quarter, and has the situations that floating matters such as moss, moss and the like are blocked locally by filter materials and the like on the surface, so that the ecological purification treatment gallery is cleaned manually and simply in time to clean a surface dirt layer; the cleaning object can be buried in shallow layers for fertilizer fields with the thickness of 30 cm-50 cm, and vegetation and plant landscape bushes or seedlings can be planted, so that organic recycling is realized.
It is further described that, through experimental detection, the sewage treated by the ecological purification treatment gallery of the application effectively solves the problem that indexes such as chromaticity, turbidity, solid particle content, nitrogen and phosphorus in water exceed standard, and achieves class III standard, but the cost is only phyllostachys pubescens, geotechnical fabric net 10, dense mesh net 9, floating blocks made of plastics and some plants which are easy to grow.
