Background
At present, the technology for removing suspended matters in micro-polluted water bodies such as river water bodies mainly comprises the following steps: coagulating sedimentation, air floatation, and filtration. The coagulating sedimentation method is to add chemical flocculating agent into water body, and separate and remove suspended matters in the water body after the step of mixing, flocculating and precipitating. The air-float method is to utilize a great amount of micro-bubbles generated in water to form a three-phase mixture of water, air and removed substances, and promote the micro-bubbles to adhere to suspended impurities in sewage and float to the water surface under the combined action of various forces such as interfacial tension, bubble rising buoyancy, hydrostatic pressure difference and the like. The simple filtering method is to filter the sewage containing suspended matters by using a filtering medium, and the water flows out from the medium under the action of external force, so that the suspended matters are trapped.
The applicant found that the prior art has at least the following technical problems: the coagulating sedimentation method needs chemical agents and related adding devices, a mechanical stirring and mixing system, a flocculation sedimentation tank and other structures, and has large equipment occupation, more electric equipment and higher energy consumption. The air floatation method is suitable for treating the sewage containing suspended particles which are not much different from water density. The simple filtration method needs to boost pressure of the inlet water, regularly back flush, reset or replace the filter medium, and the purified water needs to be pumped out by using a water inlet pump and the like, so that the energy consumption is high. The method is mainly applied to water bodies with small water treatment quantity and water quality in which suspended matters cannot be too high.

Referring to fig. 1, the liquid seal tank 4 is located in the water outlet channel 5 and is communicated with the water outlet channel 5, and the bottom of the catchment area 102 is higher than the water outlet of the water outlet channel 5. The function of the liquid seal tank 4 is to make the water outlet end of the siphon pipe component form a certain negative pressure, so as to be convenient for forming siphon effect.
In the micro-polluted water body purifying device of the embodiment, the water inlet component introduces micro-polluted water bodies into the filtering device 3 of the filtering area 101, and the filtering device 3 filters and degrades part of suspended matters such as sludge and the like to realize sludge in-situ reduction; the purified water enters the catchment area 102, the siphon pipe component leads out the water in the catchment area 102 to the liquid seal tank 4 under the siphon action, and power devices such as a drainage pump and the like are not required to be additionally arranged, so that the structure is simple, and the energy consumption is low; and the siphon pipe assembly rapidly drains water and brings air into the filter device 3 to oxygenate, so that the dissolved oxygen concentration of the discharged water is synchronously improved, and the self-cleaning capacity of the water body is improved. The device aims at slightly polluted water bodies at river channel inlets and lakes, can remove suspended matters in water, increase the transparency of the water bodies, improve the dissolved oxygen in the water bodies and increase the self-cleaning capacity of the water bodies.
In this example, a specific implementation of a siphon tube assembly is provided:
referring to fig. 1, the siphon assembly includes a siphon main pipe 1, the siphon main pipe 1 including a vertical water inlet pipe section 12, a horizontal pipe section 11, and a vertical water outlet pipe section 13, wherein: the both ends of horizontal pipe section 11 are linked together with the upper end of vertical intake pipe section 12 and the upper end of vertical play water pipe section 13, and the water inlet end of vertical intake pipe section 12 stretches into catchment district 102 bottom, and the play water end of vertical play water pipe section 13 stretches into in the liquid seal groove 4, and the play water end of vertical play water pipe section 13 is less than the water inlet end of vertical intake pipe section 12, and horizontal pipe section 11 is the highest water level pipe section of siphon subassembly, and when the water level of catchment district 102 was higher than horizontal pipe section 11, the siphon subassembly can be with the water introduction in catchment district 102 in the liquid seal groove 4.
Referring to fig. 1, when the water level in the catchment area 102 is higher than the horizontal pipe section 11, because the siphon main pipe 1 forms an inverted U-shaped pipe structure, water flows into the horizontal pipe section 11 from the inlet of the vertical water inlet pipe section 12, because the liquid sealing pressure of the outlet of the vertical water outlet pipe section 13 is higher than the outlet pressure of the siphon auxiliary pipe 15, air in the siphon main pipe 1 is firstly discharged from the exhaust pipe 16, during the exhaust process, the water flow in the siphon main pipe 1 firstly flows out of the siphon auxiliary pipe 15, under the driving action of the water flow, negative pressure is formed in the siphon main pipe 1, a siphon effect is formed in the siphon main pipe 1 to absorb the water in the catchment area 102, and the water in the catchment area 102 flows into the liquid sealing groove 4 through the vertical water inlet pipe section 12, the horizontal pipe section 11 and the vertical water outlet pipe section 13 in sequence, and then flows out through the water outlet channel without arranging drainage water
An isokinetic device.
If the water level is lowered to the position of the water inlet end of the siphon main pipe 1 as the end time point of the siphon effect, the following problems may occur: when the liquid level of the catchment area 102 is reduced to the water inlet end of the vertical water inlet pipe section 12, the siphoning effect just disappears, the water flow in the siphon main pipe 1 is not discharged, negative pressure still exists in the siphon main pipe 1, and if the water inlet component is started at this time, the water enters the siphon main pipe 1 again under the action of the negative pressure in the siphon main pipe 1 (the water inlet is not driven by the siphoning effect at this time), so that continuous water flow is formed, and the water level in the catchment area 102 is influenced to continuously rise.
In view of the above problems, as an alternative embodiment, the water level at the end of the siphon effect in the siphon assembly in this example is higher than the water inlet end of the siphon main pipe 1.
Referring to fig. 1, the siphon assembly further includes a siphon break pipe 14, the siphon break pipe 14 is communicated with the vertical water inlet pipe section 12, the water inlet end of the siphon break pipe 14 extends into the bottom of the water collecting zone 102, and the water inlet end of the siphon break pipe 14 is higher than the water inlet end of the vertical water inlet pipe section 12. As an alternative embodiment, referring to fig. 1, the siphon break pipe 14 has a pipe inner diameter smaller than that of the siphon main pipe 1.
In this embodiment, the water inlet end of the siphon break pipe 14 is higher than the water inlet end of the siphon main pipe 1, and when the water level in the water collecting area 102 is reduced to the water inlet end position of the siphon break pipe 14, air enters the siphon main pipe 1 through the siphon break pipe 14, and the siphon effect is immediately lost. Very little air entering the siphon assembly can be located in the siphon break pipe 14, preventing a continuous flow of water into the siphon main pipe 1 when the siphon effect is lost.
In this embodiment, the siphon break pipe 14 prevents the siphon action from just disappearing, and the re-water inlet causes a continuous flow in the siphon main pipe 1.
In the micro-polluted water body purifying device in the embodiment, the water level node at the beginning of the siphoning action is different from the water level node at the moment of the disappearance of the siphoning action, and the water level node at the moment of the disappearance of the siphoning action is positioned above the water level node at the beginning of the siphoning action, so that the continuous flow in the siphon main pipe 1 caused by water inflow again when the siphoning action just disappears can be prevented.
If air exists in the siphon pipe assembly, no siphon effect is formed in the siphon pipe main pipe. When the siphon action starts, in order to discharge the air inside the siphon tube assembly as soon as possible, as an alternative embodiment, see fig. 1, the siphon tube assembly further comprises an exhaust pipe 16 and a siphon auxiliary pipe 15, wherein: the upper end of the siphon auxiliary pipe 15 is communicated with the horizontal pipe section 11, and the lower end of the siphon auxiliary pipe extends into the liquid seal groove 4; the exhaust pipe 16 is arranged on the exhaust valve 17, an air inlet of the exhaust pipe 16 is communicated with the horizontal pipe section 11, and an air outlet of the exhaust pipe 16 is communicated with the siphon auxiliary pipe 15.
