Abstract

The invention discloses a tap water flocculation purifying agent, which is composed of chitosan, polyaluminum trichloride, montmorillonite auxiliary agent and powdered activated carbon, wherein the powdered activated carbon accounts for 5-12wt% of the total amount, and the shell Polysaccharide is a 0.05wt%-0.5wt% chitosan solution made by dissolving 1% glacial acetic acid; polyaluminum trichloride is a 5-15wt% polyaluminium chloride solution; montmorillonite additive It is a 1wt%-6wt% montmorillonite solution prepared with distilled water and composed of montmorillonite: sodium polyphosphate: sodium carbonate in a weight ratio of 40-70: 15-25: 10-20; chitosan Sugar solution: polyaluminum trichloride solution: montmorillonite solution is 1:3:1 (weight ratio). Compared with polyaluminum trichloride, the present invention reduces residual aluminum ions by more than 65% and reduces turbidity by more than 20% in the treated tap water, and the treatment cost is lower, which is better than that of water treated with traditional tap water flocculants.

Description

technical field [0001] The invention relates to a tap water purifier, in particular to a tap water flocculation purifier. Background technique [0002] The traditional purification treatment of drinking water in my country generally uses alum flocculation purification agent; the most common treatment process in tap water factories is: water source---coagulation---precipitation---filter---disinfection--- ---Users, if the water quality of the water source is special, the treatment process may be different. For example, if the water quality is good, the sedimentation step can be omitted. In the process of tap water preparation, aluminum ions will inevitably be brought in. After the residual aluminum ions in the water enter the human body, some aluminum ions will be excreted with feces, but some aluminum ions will be enriched in the human body, and long-term accumulation will cause pathological changes. According to foreign reports, aluminum ions can cause diseases such as dement...
