Description

[TECHNICAL FIELD]

[0001] The utility model relates to water treatment technical field, concretely is a kind of high-efficiency algae-removing drinking water treatment device. [BACKGROUND]

[0002] At present, the seasonal algal outbreak problem caused by water body eutrophication is more and more prominent, and the conventional water purification process has poor removal effect on algae, which seriously threatens the drinking water supply safety. Ultrafiltration technology with high pollution removal efficiency will have wide application prospect in drinking water treatment, but under the background that natural water body eutrophication phenomenon cannot be effectively controlled, membrane pollution caused by algae will seriously restrict the ultrafiltration water purification process.

[0003] The principle adopted by the prior art is: first, add polyaluminum chloride and sodium hypochlorite into raw water, carry out grid flocculation and inclined tube sedimentation conventional treatment, then use high-efficiency filter brick filter to carry out high-efficiency treatment on the settled water, and finally flow the treated clear water into the clear water tank for disinfection treatment before drinking.

[0004] The steps are mainly as follows: first, use a pipeline static mixer to mix polyaluminum chloride and residual chlorine added by polyaluminum chloride dosing system and sodium hypochlorite dosing system with raw water and enter the grid flocculation reaction tank through the input pipeline, and the vortex reaction and coagulant generated inside the grid flocculation reaction tank are mixed; then, the mixed water mixed by the pipeline static mixer and entering the grid flocculation reaction tank is subjected to multi-box automatic circulation and stirring inside the grid flocculation reaction tank, so that the suspended solids and coagulant in the water are contacted and reacted again, separated, and the sludge and particles are preliminarily settled, and the settled sludge and particles sink to the bottom of the tank and are automatically discharged through the blowdown pipe; the alumen flowers formed by the mixing and stirring of the grid flocculation reaction tank flow into the inclined tube sedimentation tank for secondary sedimentation, the particles are separated from the water again by the honeycomb inclined tube filler inside the inclined tube sedimentation tank, the alumen flowers are settled to the bottom by gravity, the suspended solids and colloidal particles in the water are further removed, the settled sludge and particles sink to the bottom of the tank and are automatically discharged through the blowdown pipe; finally, the settled water flows into the high-efficiency filter brick filter for filtration, effectively intercepts the small particles, bacteria, viruses or other particles in the water, ensures the safety of the effluent, and the filtered water flows to the backwash tank, and then is pumped back to the high-efficiency filter brick filter from the backwash tank for repeated washing and filtration, and finally the treated clear water flows into the clear water tank for disinfection treatment before drinking.

[0005] However, this existing technical solution has the following main shortcomings: The solution involves first adding polyaluminum chloride and sodium hypochlorite to the raw water for conventional treatment such as grid flocculation and inclined tube sedimentation; then using a high-efficiency filter brick to treat the settled water; finally, the treated water is discharged into a clear water tank for disinfection before drinking, thus achieving the desired treatment effect. However, under actual operating conditions, its effectiveness against fine particulate colloidal dissolved matter (organic matter, heavy metals, etc.) in the water is limited. The most advanced treatment in the process is filtration using porous granular filter media such as quartz sand (coarse filtration), which has limited effectiveness and suffers from high wastewater rates.
