Description

Technical Field

[0001] The invention relates to sewage treatment equipment, in particular to an ultrasonic cleaning device for ecological dam filter material. Background Art

[0002] Ecological filter dam, also known as permeable dam, filtration dam, etc., is a technology developed by combining artificial wetlands and rapid infiltration principles. It usually uses gravel, pebbles, crushed stones, etc. as filter materials to fill the built dam body, which can purify water quality and promote the sedimentation of suspended matter and nutrients in rivers. This technology does not affect flood discharge and has the advantages of simple structure and low construction cost. Therefore, it can be applied to river regulation. In addition, it can also be used for urban initial rainwater treatment and freshwater aquaculture tailwater treatment.

[0003] From the perspective of pollutant removal, the ecological filter dam moves pollutants in the water to the surface of the filter material. Therefore, it cannot decompose and consume pollutants like a biological pond, but only achieves spatial transfer. After the ecological dam has been in operation for a period of time, a certain amount of pollutants (sludge) will accumulate on the surface of the filter material. As the pollutants continue to increase, it will have two effects:

[0004] 1. The quality of the effluent water deteriorates because the interaction between the pollutants on the outermost layer of the filter material and the filter material or other pollutants is weakened, and the pollutants are transferred back into the water body under the action of the shear force of the water flow;

[0005] 2. The head loss increases, resulting in the inability to filter. The reason is that the pores of the filter material decrease, the water flow rate increases, and the head loss coefficient increases. At this time, the ecological filter dam will not be able to continue to operate. The filter material must be cleaned or replaced before the filter dam can continue to operate. Replacing the filter material is bound to cause huge waste and high cost. If the filter material is to be cleaned, a large amount of manpower is required, which is not only inefficient and has poor cleaning effect, but also costly. At the same time, the sludge generated by cleaning is not properly handled and disposed of, which has an adverse impact on the environment. Summary of the invention

DETAILED DESCRIPTION

[0049] The present invention is described in further detail below.

[0050] Example 1: See Figure 1-Figure 12 An ultrasonic cleaning device for filter material of an ecological dam comprises a box body 1, an isolation plate 4 is arranged inside the box body 1, two sides of the isolation plate 4 form a cleaning area and a coagulation and sedimentation area, and also comprises a dosing device, a water injection device and a filter material fixing component.

[0051] The dosing device is arranged above the box body 1; the water injection device is arranged at the bottom of the box body 1; the filter material fixing assembly is arranged in the cleaning area; an inclined plate 21 is arranged in the cleaning area, and a connecting pipe 22 is connected to the bottom of the inclined plate 21, one end of the connecting pipe 22 is fixed to the center of the inclined plate 21, and the other end of the connecting pipe 22 is fixed to the outer wall of the isolation plate 4; an inclined plate 16 is arranged in the coagulation and sedimentation area, and a scraper assembly is slidingly arranged on the inclined surface of the inclined plate 16.

[0052] The filter material fixing assembly includes a filter material support plate 11, positioning rails 19 are arranged on both sides of the filter material support plate 11, the positioning rails 19 are fixed on the inner wall of the box body 1, a filter material fixing frame 5 is arranged above the filter material support plate 11, a through hole is opened on the outer wall of the filter material support plate 11, a "cross"-shaped sealing plate fixing frame 20 is arranged in the through hole of the outer wall of the filter material support plate 11, a sealing plate 12 is arranged below the sealing plate fixing frame 20, and the sealing plate 12 is attached to the bottom of the through hole of the outer wall of the filter material support plate 11, a reciprocating screw rod 26 is arranged at the center of the filter material support plate 11, and an ultrasonic vibrator 28 is arranged above the filter material support plate 11.

[0053] The dosing device is used to add flocculant and transfer the flocculant into the sewage. The water injection device is used to guide water and transport water into the box 1. The filter material fixing component is used to fix the filter material and fix the position of the filter material to facilitate the cleaning of the filter material. At the same time, the filter material support plate 11 moves up and down, and the filter material is driven to move up and down by the filter material support plate 11, so that the filter material can move up and down in the water, thereby improving the cleaning effect. The ultrasonic vibrator 28 is on the filter material support plate 11, and the water is driven to vibrate by the ultrasonic vibrator 28, and the filter material is cleaned by the vibrating water.

[0054] Preferably, the water injection device includes a stacking pump 10, the input end of the stacking pump 10 is connected to an inlet pipe 8, the output end of the stacking pump 10 is connected to an outlet pipe 6, and the end of the outlet pipe 6 away from the stacking pump 10 is connected to a transverse pipe 7, and the transverse pipe 7 is located above the cleaning area.

[0055] The superposition pump 10 sucks water through the water inlet pipe 8, and guides the water to the cleaning area in the box body 1 through the water outlet pipe 6, so as to provide clean water for the box body 1. The outer wall of the horizontal pipe 7 is provided with a through hole. When no filter material is placed in the box body 1, it is necessary to first fill the box body 1 with water so as to make the ultrasonic vibration scrubbing effect play a role.

The dosage needs to be determined according to the type and amount of pollutants loaded on the filter material. The dosage of the coagulant is in the range of 5mg / L-200mg / L relative to the amount of cleaning wastewater generated in the box 2, preferably 20mg / L-60mg / L.

[0059] The motor 3 can drive the fixed rod 14 to rotate, and the fixed rod 14 will drive the material-moving rod 13 to rotate. The flocculant is moved into the through hole at the bottom of the dosing box 2 through the material-moving rod 13, so that the flocculant can fall into the coagulation and sedimentation area in the box body 1 to flocculate the sewage.

[0060] The power of motor 3 is sufficient to deliver 30W / m 3 The power of motor 3 can be adjusted by frequency conversion. After adding coagulant, the steps of discharging sludge and clean water are as follows:

[0061] (i) Motor 3 rotates at 100% of the total power for 30s-120s;

[0062] (ii) the motor 3 rotates at 40% to 60% of the total power for 3 to 5 minutes;

[0063] (iii) Motor 3 rotates at 20% to 35% of the total power for 5 to 8 minutes;

[0064] (iv) Motor 3 rotates at 10%-15% of the total power for 8-15 minutes;

[0072] The transmission rod 17 can drive the transmission rod 4 27 and the transmission rod 2 18 to rotate. The transmission rod 2 18 adopts a screw rod. When the transmission rod 2 18 rotates, it can drive the scraper 29 to reciprocate on the inclined surface of the inclined plate 16, so that the driving scraper 29 can drive the sludge impurities on the inclined surface of the inclined plate 16 to move toward the position of the mud discharge pipe 9, thereby improving the sludge discharge efficiency.

[0079] The working principle of the ultrasonic cleaning device for filter media of the ecological dam: when the device is in use, the filter media to be cleaned is first set inside the filter media fixing frame 5, and the superposition pump 10 is started. The superposition pump 10 sucks water through the water inlet pipe 8, and at the same time, the water is discharged to the cleaning area in the box body 1 through the water outlet pipe 6 to provide clean water for the box body 1. Then, the water is driven to vibrate by the ultrasonic vibrator 28, and the filter media is cleaned by the vibrating water. At the same time, the motor 3 is started, and the motor 3 can drive the fixed rod 14 to rotate, and the fixed rod 14 will drive the material moving rod 13 to rotate, and the flocculant is moved to the through hole at the bottom of the dosing box 2 through the material moving rod 13, so that the flocculant can fall into the coagulation and sedimentation area in the box body 1 to flocculate the sewage; when the fixed rod 14 rotates, the fixed rod 14 can drive the transmission rod three 24 to rotate, and the transmission rod three 24 can drive the transmission rod one 17 to rotate, and one end of the transmission rod one 17 can be connected to one end of the auger 23, and the transmission rod When the filter support plate 11 is moved up and down, the filter material is driven to move up and down by the filter support plate 11, thereby improving the cleaning effect of the filter material in the water.
