[0033] Such as figure 1 As shown, based on the above-mentioned copper-loaded antibacterial porous ceramsite filler, the present invention also provides a preparation method for copper-loaded antibacterial porous ceramsite filler, which includes the following steps:
[0034] S1. Provide steelmaking slag, and carry out copper-loading treatment on the steelmaking slag:
[0035] S21, soaking the steelmaking slag in hot water, cleaning and drying the soaked slag;
[0036] S22. Grinding the dried steelmaking slag, and screening out powder meeting the particle size requirement;
[0037] S23, placing the screened powder in CuCl 2 soaking in the solution, air-drying and drying the soaked powder to obtain the powder of steelmaking slag treated with copper loading.
[0038] Among them, due to the rich iron element in the steelmaking slag, through CuCl 2 After soaking and high-temperature calcination to form copper products, the contained Cu element is more uniform and dense, and it i...

The invention provides a copper-loaded antibacterial porous ceramsite filler and a preparation method of the copper-loaded antibacterial porous ceramsite filler. The copper-loaded antibacterial porous ceramsite filler is prepared from the following components in parts by weight: 75 to 90 parts of powder of steelmaking slag subjected to a copper loading treatment, 10 to 15 parts of pore forming agent and 3 to 7 parts of bonding agent, wherein the pore forming agent is prepared from the following components in percentage by weight: 60% of wood chips, 15% of pulverized coal and 25% of limestone powder. The copper-loaded antibacterial porous ceramsite filler has the advantages that the filler can be applied to the fields, such as micro-polluted source water filtration, biological sewage treatment, landscape gardening, and the steelmaking slag is recycled, therefore the effect of turning waste into treasure is achieved.
Description
technical field [0001] The invention relates to the technical field of water treatment, in particular to a copper-loaded antibacterial porous ceramsite filler applied in the field of water treatment and a preparation method thereof. Background technique [0002] The copper-loaded antibacterial porous ceramsite filler has a wide range of uses, and it can be applied in the field of water treatment for filtration and contact disinfection. Scientific research has found that water mixed with trace amounts of copper has an amazing bactericidal effect, that is, only one-thousandth of copper ions can kill algae, and only a small amount of copper can kill algae, aquatic organisms and microorganisms in water effect. Subsequent studies have found that many metals and their ions have antibacterial properties, and the order of antibacterial ability is as follows: Ag≥Hg≥Co≥Ni≥Zn≥Cu≥Fe﹥Mn﹥Ba≥Mg≥Ca. Among metal ions, especially silver, mercury, zinc, and copper have the strongest bacteric...
