Further, the processing method of a kind of industrial wastewater according to above-mentioned design, it is characterised in that carrying out
Also need to be pre-processed before the step a, adjust pH value first to alkalescent, diatom is then added into industrial wastewater
Mud, then continuously stirs industrial wastewater 30 minutes, and standing sedimentation, removes grease, the bulky grain pollutant in industrial wastewater afterwards
With small particles of pollution thing;Then pH value is adjusted to faintly acid.
The beneficial effects of the invention are as follows:Handling process is simple, and treatment effeciency is high, high treating effect, aluminium polychloride and carbon
The multinuclear high price complex ion that aluminium, magnesium ion in sour magnesium are formed, these multinuclear high price complex ions are to negatively charged phosphate radical, phosphorus
Sour hydrogen radical, dihydrogen phosphate produce association suction-operated, water-soluble low ionic associate are formed, so as to reach certain dephosphorization
Effect, make full use of iron ion to mutually compensate for performance with aluminum ions, efficiently avoid metal ion and model is used to water purification agent
The limitation enclosed, nanosized SiO_2 have very strong adsorption capacity, can adsorb the formaldehyde in waste water, its PARA FORMALDEHYDE PRILLS(91,95) not only has physics
Absorption, and there is chemisorbed, hydrogen bond or covalent bond are formd with formaldehyde, can be reduced the content of formaldehyde in waste water.
