Technical Field

The invention relates to the technical field of water body treatment, in particular to automatic pond purification equipment for an adjacent road.

Background

In most areas, ponds often become the collection place of rural domestic sewage, and after pesticides are sprayed in farmlands, the ponds are easy to flow into the ponds, because the ponds generally lack fluidity, pollutants are naturally degraded only by ecological crops such as reeds at the sides of the ponds, and the degradation amount is far less than the input amount of the pollutants, so that a plurality of ponds are seriously polluted, and become the most serious part of rural pollution.

At present, common treatment methods for pond water body treatment include:

ecological treatment, phytoplankton planting and the like, but the method is greatly influenced by seasons, plants stop growing and are withered and yellow in winter, timely harvesting is needed, time and labor are wasted, the amount absorbed by the plants is very limited, and part of nitrogen and phosphorus absorbed by the plants and organic matters return to a water body due to metabolism in the plant growth process;

chemical treatment, namely adding bleaching powder or quicklime, and has the defects of destroying the ecological balance of the aquaculture water and having the risk of secondary pollution;

the physical method mainly eliminates pollutants through physical processes such as dredging, precipitation, filtration and the like, but has higher cost.

wherein, the first one-way valve 5 is configured to enable water to enter the water inlet cavity 1-1 from the outside; the second one-way valve 15 is configured such that water can pass from the conduit 19 into the manganese sand filter 3.

In this embodiment, the bottom end of the sleeve 12 and the bottom end of the nozzle 13 are both fixed on the bottom plate 16, a through hole 16-1 is formed at a position where the bottom opening of the nozzle 13 is opposite to the bottom plate 16, the top end of the conduit 19 is fixed on the bottom plate 16, and a channel 16-2 for communicating the conduit 19 and the interlayer 14 is formed on the bottom plate 16; so that the water overflowing from the slit 11-11 and carrying a small amount of sodium persulfate can reach the conduit 19 from the channel 16-2 of the interlayer 14 and flow into the manganese sand filter material 3 from the conduit 19; the through hole 16-1 on the bottom plate 16 can communicate the spray pipe 13 with the aerobic biological filler 2, so that water enters the spray pipe 13 through the through hole 16-1 after passing through the aerobic biological filler 2 and is sprayed out of the spray pipe 13.

In the embodiment, an annular wing 17 is sleeved outside the cone bucket 11, and the top of the annular wing 17 is fixedly connected with the top of the cone bucket 11; a part of the water sprayed by the spray pipe 13 falls on the annular wing 17 for aeration treatment, so that the oxygen content of the water is increased;

in this embodiment, the annular wing 17 is tapered, and has a smaller upper end and a larger lower end.

In the embodiment, a plurality of outer steps 17-1 protrude upwards from the upper surface of the annular wing 17; thereby increasing the surface area of the annular fin 17 and prolonging the residence time of water on the annular fin 17, thereby improving the aeration effect.

In this embodiment, the upper surface of the outer step 17-1 is covered with a photocatalyst layer 18; so that the photocatalyst layer 18 can be used to degrade and remove organic contaminants in the water located on the surface of the outer step 17-1.

in this embodiment, the elastic plate 9 is made of spring steel.

The principle of the automatic pond purification device for the adjacent roads in the embodiment is as follows:

placing the barrel body 1 into a pond, keeping a nozzle 13-1 of a spray pipe 13 above the barrel body 1 higher than the liquid level of the pond, wherein the height of the barrel body 1 can be customized according to the water depth of the pond, or optionally placing the barrel body 1 at a position at a proper water depth of the pond, so that more than half of the position of the sleeve 12 is exposed out of the water surface;

then placing the second rubber ball 7 on the adjacent road surface 10, and correspondingly fixing the elastic plate 9 on the road surface 10, so that the second rubber ball 7 is limited and protected in the elastic plate 9;

under the action of the pressure difference of water in the pond, water can enter a water inlet cavity 1-1 at the bottom of a barrel body 1 from a first one-way valve 5, when pedestrians or vehicles pass through an elastic plate 9, the elastic plate 9 presses a second rubber ball 7 downwards, gas of the second rubber ball 7 enters a first rubber ball 6, and the first rubber ball 6 is expanded, so that the water in the water inlet cavity 1-1 automatically flows through an anaerobic biological filler 4, a manganese sand filter material 3 and an aerobic biological filler 2 in sequence and is sprayed out from a spray pipe 13;

the water sprayed by the nozzle 13 is divided into two parts:

one part of the water escapes from the periphery and falls on the annular wings 17 to carry out aeration treatment, the oxygen content of the water is increased, and meanwhile, the water and the photocatalyst layer 18 on the annular wings 17 are subjected to photocatalysis so as to degrade and remove organic pollutants in the water on the annular wings 17 and finally return to the pond, and the water rich in dissolved oxygen can promote the growth of microorganisms in the water after entering the pond and improve the self-purification capacity of the water body;

the other part of the water falls on the surface of an inner step 11-1 in the conical hopper 11 and flows into the slit 11-11 along the inner surface of the conical hopper 11, then the water overflowing from the slit 11-11 carries a small amount of sodium persulfate, then the water falls into the interlayer 14 and returns to the manganese sand filter material 3 through the conduit 19, after the water carrying a small amount of sodium persulfate is contacted with the manganese sand filter material 3, the main component manganese dioxide of the manganese sand catalyzes the sodium persulfate to generate sulfate radical free radicals to oxidize organic matters in a water body, and meanwhile, the water returned to the manganese sand filter material 3 by the conduit 19 contains more dissolved oxygen and can be taken into the aerobic biological filler 2, so that the effect of aerobic reaction is improved.

When the elastic plate 9 loses the compression, the elastic plate 9 and the second rubber ball 7 rebound, and water in the pond enters the water inlet cavity 1-1 at the bottom of the barrel body 1 through the first one-way valve 5 again under the action of the pressure difference of the water in the pond.

The anaerobic biological filler 4 is arranged at the lowest part of the barrel body 1 and is positioned at the deep part of the pond, and the oxygen content of water at the deep part of the pond is lower, so that the anaerobic reaction can be favorably carried out, meanwhile, macromolecular organic matters in the water can be degraded into micromolecular organic matters through the anaerobic reaction, and the water is subjected to denitrification and dephosphorization, so that the eutrophication of a water body of the pond is avoided;

when the water treated by the anaerobic biological filler 4 passes through the manganese sand filter material 3, the chemical catalytic oxidation effect is generated, and the organic matters in the water are continuously degraded;

the water treated by the manganese sand filter material 3 is subjected to aerobic reaction by the aerobic biological filler 2, and can be subjected to denitrification, dephosphorization and organic pollutant degradation again.

The sodium persulfate in the slit can be supplemented regularly according to the water quality of the pond water body.
