Physical and chemical regularity and the mechanism of process complex coagulation and oxidative wastewater treatment, low-purity by surfactants and dyes are investigated. The basic regularity of regeneration of valuable components of the sludge formed after complex wastewater treatment is revealed. High performance of use of regenerated solution of a coagulant for discoloration of typical wastewater in a mix with original solution of iron (II) sulphate is established.The extent of discoloration remains high during four cycles and exceeds 90 % at a doze of iron of 120 mg/dm3.

Key words: complex coagulation, oxidative treatment, wastewaters, SAA, sludge.
