Example Embodiment
[0016] Example 1: Treating 100 tons / day of cyanobacteria slurry produced in Dianchi Lake. The water content of the cyanobacteria slurry is about 97-99%. The sludge pump is pumped into the market and has a processing capacity of 8 tons / hour. The material is dewatered by the sedimentation centrifuge, and the cyanobacteria slurry is added with 0.5ppm of cationic organic polymer flocculant by pipeline dosing before entering the horizontal spiral unloading sedimentation centrifuge. After the horizontal spiral unloading sedimentation centrifuge is started, the cyanobacteria slurry suspension is added to the spiral inner cylinder from the feeding tube, and then flows into the drum. Under the action of centrifugal force, the cyanobacteria solid phase settles on the wall of the drum, and the algae are dewatered by centrifugation. The cake has a moisture content of 75%-90%, which turns the liquid algae slurry into a semi-solid algae cake and greatly reduces its volume. The screw conveyor pu...
