| titleOfInvention | Liquid waste disposal using iron salt flocculant |
| abstract | PURPOSE: To efficiently remove heavy metals and organic substance, by adding the liquid mixture of ferrous and ferric salt solutions whose ORP value will come to 460W540mV to waste water, and then adding alkali in an amount of 1 equivalent or more to the total of acid radicals in the liquid waste. n CONSTITUTION: The liquid mixture of ferrous and ferric salt solutions whose ORP value will come to 460W540mV is added to liquid waste containing various heavy metals and/or liquid waste containing organic substance such as animal and plant oils and blood under a suspended condition. Thereafter, a pH is adjusted to 7W10 by adding alkali or its aqueous solution in an amount of 1 equivalent or more to the total of acid radicals in the liquid waste to form Fe 3 O 4 , FeOOH, etc. Hence, the heavy metals and/or organic substance in the liquid waste are removed by introducing or adsorbing them into or onto the formed crystal lattices. The liquid mixture of said ferrous and ferric salt solutions is pref. added at the ratio such that the iron ions are contained in an amount of 2W30 times the total mol number of the heavy metals in the liquid waste. n COPYRIGHT: (C)1984,JPO&Japio |
