The invention relates to the treatment of water, particularly to industrial, waste water. A process for the preparation of highly concentrated with mineral, organic and nitric substances waste water for baromembrane treatment consists in reagent treatment with salts of bivalent metals of iron and magnesium, at mass ratio of ions of Fe: Mg, equal to 1:(2-3) mg/dm. The process is carried out in two stages. On the first stage it is treated with reagent at pH of 10-12, and on the second – it is bubbled with air with rate of 5000-7500 m/mof water. Produced in two stages sediments are mixed and heat treated. The realization of the process provides the treatment degree of the prepared water from ammonia nitrogen 95-99 %, from organic substances 42-66 %. |
