Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to low-concentration fluorine-containing wastewater treatment equipment. Background Art

[0002] There are many methods for treating fluoride wastewater. Commonly used methods at home and abroad can be roughly divided into two categories, namely precipitation and adsorption. Among them, chemical precipitation is commonly used to treat low-concentration fluoride wastewater. The main principle is to add chemical precipitants such as lime, calcium chloride, carbide slag into the sedimentation tank to form insoluble precipitates (calcium fluoride) with fluoride ions in the water, thereby achieving the separation of fluoride ions in the wastewater.

[0003] The patent with publication number CN209259823U discloses an integrated treatment equipment for fluorine-containing wastewater. The equipment realizes the precision of reagent addition and working condition control through the precise control of PLC and various online instruments, reduces reagent waste, reduces precipitation output, and achieves the treatment and discharge of fluorine-containing wastewater in compliance with the standards. It is small in size and easy to move. However, when the equipment treats wastewater, it is necessary to wait for the wastewater to settle in the sedimentation tank before discharging the reacted wastewater. The waiting time is relatively long, which affects the wastewater treatment efficiency. In addition, the reaction tank and sedimentation tank of the equipment are set separately, occupying a large area, so further improvement is needed. Utility Model Content

[0025] A second electromagnetic valve 8 is fixedly connected to the middle of the drain pipe 7. By opening the second electromagnetic valve 8, the waste water after the reaction inside the box body 1 can be discharged along the drain pipe 7.

[0026] The anti-blocking component 11 includes a vertical rod 111, a sleeve 112 is slidably connected to the bottom surface of the vertical rod 111, a second spring is fixedly connected to the inner bottom wall of the sleeve 112 and the bottom of the vertical rod 111, a plurality of scrapers 113 are fixed to the bottom end of the sleeve 112, a top plate 114 is fixedly connected to the top of the vertical rod 111, and two plug plates 115 are fixed to the upper surface of the top plate 114, and a card hole 116 is opened in the middle of the plug plate 115.

[0027] In this embodiment, the vertical rod 111 and the sleeve 112 are both square structures, so that the vertical rod 111 can drive the scraper 113 at the bottom of the sleeve 112 to rotate. The bottom of the scraper 113 contacts the surface of the filter 5. After the scraper 113 rotates, it can prevent sediment from accumulating on the surface of the filter 5.
