Composite immobilized enzyme material for repairing polluted water source and its preparing process

[0024] Carry out by above-mentioned specific embodiment, the raw material formula weight of immobilized enzyme composite material is: construction waste (3~5mm of particle diameter) 70%, fly ash 20%, rosin soap 0.5%, calcium oxide expansion agent 0.5%, enzyme liquid 9% (enzyme activity 2000u / ml), add an appropriate amount of water, mix and stir the materials, the stirring speed is 10-20 rpm, and the stirring time is 30-60 minutes; stand for nitrification; then mix and stir evenly to make the sludge The moisture content is 22%, and it is left to stand at room temperature for 1 to 2 hours, then sent to a non-burning brick machine for pressing and forming, and naturally air-dried to obtain the product. The model is: P-HST30, Mianshaozhuanji.

[0025] When the above-mentioned immobilized enzyme composite material is used for printing and dyeing wastewater treatment, firstly, the immobilized enzyme composite material (block material with an outer diameter of 36×24×12cm) is filled in

[0028] Carry out by above-mentioned specific embodiment, the raw material formula weight of immobilized enzyme composite material is: ceramic particle (3~5mm of particle diameter) 60%, portland cement 10%, fly ash 20%, rosin soap 0.5%, calcium oxide Expanding agent 0.5%, enzyme preparation (solid state) 9% (enzyme activity 2000u / mg), add appropriate amount of water, mix and stir the materials, stirring speed is 10-20 rpm, stirring time is 30-60 minutes; stand for nitration and then mix and stir evenly, so that the moisture content of the mud is 25%, the pH value of the mud is measured to be 6.5, and stand at room temperature for 2 to 3 hours. The product is obtained by pressing the unburned brick machine model GQC-302 and drying it in a dryer at a temperature of 40°C.

[0029] The above-mentioned immobilized enzyme composite material is filled in an upflow bioreactor, and the papermaking wastewater is treated (assisted physicochemical treatment at the front stage of the reactor

[0032]Carry out according to above-mentioned specific embodiment, the raw material formula weight of immobilized enzyme composite material is: pumice 65%, portland cement 18%, fly ash 8%, rosin soap 0.4%, calcium oxide expansion agent 0.4%, enzyme preparation 8.2% % (enzyme activity 2000u / ml), add appropriate amount of water after mixing and stirring the ingredients evenly, adjust the moisture content of the mud to 26%, measure the pH value of the object soaking water to 6.0, stir the speed at 10 to 20 rpm, and stir for a period of time 30 to 60 minutes; stand still for nitrification; mix and stir evenly, and stand at room temperature for 3 hours, then send it into a non-burning brick machine, and press to form, that is, the immobilized enzyme composite material with a square appearance shape is obtained. The material is weak gray in color, odorless, the enzyme activity measured indirectly is ≥18000u / kg, the compressive strength is 6mpa, the porosity is 20%, and the water perm
