| titleOfInvention | Composite medicament for reducing water hardness and removing soluble organic matters and preparation method thereof |
| abstract | The invention discloses a preparation method of a composite medicament for reducing water hardness and removing soluble organic matters in the technical field of water treatment, which enables calcium hydroxide to be deposited on the surface of nitrogen fine bubbles in a non-homogeneous way to obtain nano-scale calcium hydroxide particles; mixing the obtained nanometer calcium hydroxide particle solid powder with poly dimethyl diallyl ammonium chloride (PDADMAC) solid powder to obtain the composite medicament. The traditional softening agent calcium hydroxide only has the effect of reducing hardness, and the problem of high effluent turbidity is always difficult to solve. The compound medicament prepared by the invention can remove most of soluble organic matters on the basis of ensuring the hardness removal rate, and control the turbidity of effluent at a lower level, thereby having good application and popularization prospects. |
