Embodiment 1
[0035] The invention provides a water treatment agent containing high-porosity diatoms, which is composed of high-porosity diatoms, flocculants and auxiliary agents, and the mass ratio of the high-pore diatoms, flocculants and auxiliary agents is 60-70:20-30:1- 10.
[0036] Further, the flocculant is polyaluminum chloride.
[0037] Further, the auxiliary agent is any one of slaked lime, sodium hydroxide and magnesium oxide.
[0038] Further, the mass ratio of the high-porosity diatom, polyaluminum chloride and slaked lime is 70:25:5.
[0039] Further, the mass ratio of the high-porosity diatom and polyaluminum chloride:sodium hydroxide is 70:29:1.
[0040] Further, the mass ratio of the high-porosity diatom, polyaluminum chloride and magnesium oxide is 70:28:2.
[0041] Further, the indicators of the described high-porosity diatoms are as follows:
[0042] Chlorella mass percentage content ≥ 63%;
[0043] SiO 2 The mass percentage content is ≥59.5%;
[0044] Amorphous S...
Embodiment 2
[0058] The invention provides a water treatment agent containing high-porosity diatoms, which is composed of high-porosity diatoms, polyaluminum chloride and slaked lime, and the mass ratio of the high-porosity diatoms, polyaluminium chloride and slaked lime is 70:25:5.
[0059] Apply the product of the present invention to Beiku Sewage Treatment Plant: 20,000 tons / day, mainly printing and dyeing sewage, the effect after use is as follows:
[0060] serial number
[0061] It can be seen from the above table that the high-porosity diatom high-efficiency water purifier is used to treat printing and dyeing wastewater, and the removal rate of COD, ammonia nitrogen, total phosphorus and chroma can reach more than 93%.
Embodiment 3
[0063] The invention provides a water treatment agent containing high-porosity diatoms, which is composed of high-porosity diatoms, polyaluminum chloride: sodium hydroxide, and the mass ratio of the high-porosity diatoms, polyaluminum chloride: sodium hydroxide is 70:29: 1.
[0064] The product of the present invention is applied to Mingtong River in Kunming, and the effect after use is as follows:
[0065] The test results of the sewage treatment of Mingtong River in Kunming detected by the Yunnan Provincial Environmental Monitoring Center Station:
[0066] water sample
[0067]It can be seen from the above table that the high-porosity diatom high-efficiency water purifier is used to treat domestic sewage, the removal rate of COD can reach more than 95%, and the removal rate of TP can reach more than 90%.
