Abstract

The invention discloses a method for preparing and recovering immobilized microbiologic balls applied to a water treatment device. The immobilized microbiologic balls comprise magnetic media and activated sludge. The method for preparing and recovering the immobilized microbiologic balls applied to the water treatment device comprises the following steps: putting the activated sludge in circular holes in a plate, then putting the magnetic media in the activated sludge in the circular holes to make obtained mixtures into the immobilized microbiologic balls, using the immobilized microbiologic balls in the water treatment device, carrying out recovery after the immobilized microbiologic balls are used for a period of time, and recovering the magnetic media through ways of soaking, rolling and centrifugation; afterwards, remaking the magnetic media and the activated sludge into the immobilized microbiologic balls. The immobilized microbiologic balls not only can keep the activity of microorganisms and purify water quality, but also can separate mud from water, and are good in settleability; the diameters of the immobilized microbiologic balls are selected just right; under an action of a magnetic field, the immobilized microbiologic balls are enabled to move in a suspension manner, and the activity of the microorganisms can be also improved; the immobilized microbiologic balls can be recycled, so that the microorganisms in the immobilized microbiologic balls are enabled to be always in high-activity states.

Description

Apply the immobilized microorganism ball preparation in water treatment facilities and recovery method
Technical field
