摘要

A method and related product for purification of waste water, especially of water polluted with phosphorus, nitrogen, heavy metals, and chlorinated solvents. The purification process consists of: a) adding two liquid mixtures in sequence to the waste water; b) letting the pollutants react with the two mixtures; c) subsequently removing the sludge that forms. One of the two liquid mixtures in question is a liquid mixture of two acids that may be extracted from lignite, leonardite and fossils of vegetal origin like peat.
