Example Embodiment

[0034] Example 1:

[0035] The invention provides a water treatment agent containing high-porous diatoms, which is composed of high-porous diatoms, flocculants and auxiliary agents. The mass ratio of said high-porous diatoms, flocculants and auxiliary agents is 60-70:20-30:1 10.

[0036] Further, the flocculant 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-porous diatom, polyaluminum chloride and slaked lime is 70:25:5.

[0039] Further, the mass ratio of the high-porous diatom, polyaluminum chloride: sodium hydroxide is 70:29:1.

[0040] Further, the mass ratio of the high-porous diatom, polyaluminum chloride and magnesium oxide is 70:28:2.

[0041] Further, the indicators of the high pore diatoms are as follows:

[0042] The mass percentage content of Cyclotella ≥63%;

[0043] SiO 2 The mass percentage content of ≥59.5%;

[0044] Amorphous SiO 2 Mass percentage con...

[0057] Example 2

[0058] The invention provides a water treatment agent containing high-porous diatoms, which is composed of high-porous diatoms, polyaluminum chloride and hydrated lime. The mass ratio of the high-porous diatoms, polyaluminum chloride and slaked lime is 70:25:5.

[0059] Applying the product of the present invention to Beishui Wastewater Treatment Plant: 20000 tons / day, mainly printing and dyeing wastewater, the effects after use are as follows:

[0060] Serial number

[0061] It can be seen from the above table that the removal rate of COD, ammonia nitrogen, total phosphorus, and chromaticity can reach more than 93% by using high-porous diatom high-efficiency water purifier to treat printing and dyeing wastewater.

Example Embodiment

[0062] Example 3

[0063] The invention provides a water treatment agent containing high-porous diatoms, which is composed of high-porous diatoms, polyaluminum chloride: sodium hydroxide, and the mass ratio of the high-porous diatoms, polyaluminum chloride: sodium hydroxide is 70:29: 1.

[0064] Applying the product of the present invention to Kunming Mingtonghe, the effect after use is as follows:

[0065] Yunnan Provincial Environmental Monitoring Center Station detected Kunming Mingtonghe sewage treatment test results:

[0066] Water sample

[0067] It can be seen from the above table that the removal rate of COD can reach more than 95% and the removal rate of TP can reach more than 90% when the high-porous diatom high-efficiency water purifier is used to treat domestic sewage.

Abstract

The invention provides a water treatment agent containing high-porous diatom, which is composed of the high-porous diatom, a flocculating agent and an assistant agent according to the mass ratio of 60-70:20-30:1-10. The water treatment agent has the effects of adsorption and flocculation when being added during wastewater treatment. The water treatment agent also is combined with microorganisms in a bio-pool to serve as a bio-carrier, thus greatly improving treatment efficiency. The water treatment agent can be used for treatment of various industrial and living wastewaters, has good treatment effect, low cost, small occupied area and reduced sludge amount, and can treat the wastewater fundamentally.

Description

Technical field: [0001] The invention belongs to the field of chemical industry and relates to a water purifier, in particular to a water treatment agent containing high-porosity diatoms. Background technique: [0002] The carriers currently used in our country can be roughly divided into three categories: the first category is a fixed carrier, mainly a honeycomb carrier; the second category is a suspended carrier such as a soft carrier, a semi-soft carrier, an elastic three-dimensional carrier, a combination type carrier, etc.; the third type is stacked and suspended carriers, such as Pall rings, stepped rings, hollow spheres, suspended particles, etc. But the field of liquidity carrier is still blank. Invention content: [0003] Aiming at the above-mentioned technical problems in the prior art, the present invention provides a water treatment agent containing high-porosity diatoms. The water treatment agent containing high-porosity diatoms should solve the problem of th...
