pouring wastewater into a filter box (2) through a throwing port (22), filtering the wastewater through a filter plate (29), enabling the wastewater to enter a first stirring tank (4) through a communicating pipe (18), throwing quantitative lime into the first stirring tank (4) through a dosing port (16), and starting a second motor (14) to drive a rotating rod (33) and stirring blades (34) to mix and stir the wastewater and the lime;
secondly, outputting the wastewater in the first stirring tank (4) into the second stirring tank (6) through a connecting pipe (19), then throwing calcium chloride into the second stirring tank (6) through a dosing port (16) to accelerate precipitation, and driving a rotating rod (33) and a stirring blade (34) in the second stirring tank (6) through a belt (15) to mix and stir the wastewater, lime and calcium chloride, so that the wastewater is mixed with the lime and the calcium chloride more quickly, and the fluorine removal efficiency is improved;
step three, after the reaction of the wastewater in the second stirring tank (6) with lime and calcium chloride is finished, precipitating reactants at the bottom of the second stirring tank (6), outputting the precipitated reactants into a storage box (5) for collection by starting a water pump (20), opening a control valve (39) at the top of a water drain pipe (38) after the precipitated reactants are discharged, and discharging the wastewater with fluorine removed in the second stirring tank (6) through the water drain pipe (38);
step four, after filtering waste water at filter board (29), impurity accumulation in waste water is at filter board (29) top, drive pivot (11) through first motor (13) and rotate, and then drive first rolling wheel (12) and second rolling wheel (10) rotate, make filter board (29) rise through the rolling of stay cord (31), after filter board (29) rise to waste pipe (28) department, rotate hand wheel (27) and make two arc splint (23) remove towards the direction that keeps away from each other, and then make second rolling wheel (10) break away from with pivot (11), the stay cord (31) of single rotation second rolling wheel (10) are elongated, make filter board (29) be close to waste pipe (28) one end decline, make the solid impurity at filter board (29) top through waste pipe (28) landing to collection box (8) of collection box (3) in collecting.
