Изобретение относитс  к способам очистки производственных сточных вод, наП|ример, коксохимического производства.The invention relates to methods for the treatment of industrial wastewater, petrol coke production.

Известен способ очистки сточных вод от фенолов и роданидов биохимическим окислением с предварительным введением в сточную воду фосфорного питани  и комплексов фенол- и роданразрушающих бактерий. При времени очистки, равном 68 час, степень очистки от фенолов - 911%, от роданидов - 98%.A known method of purification of wastewater from phenols and rhodanides by biochemical oxidation with the preliminary introduction of phosphorus nutrition and complexes of phenol and rhodan disruptive bacteria into wastewater. With a cleaning time of 68 hours, the degree of purification from phenols is 911%, from rodanides, 98%.

С целью ускорени  биохимической очистки сточных вод, содержащих фенолы и роданиды, в сточную воду перед биохимической очисткой ввод т соли железа, наприме|р сернокислое железо, в количестве 10-40 г/м сточной воды . Врем  очистки сокращаетс  до 15- 20 час. Степень очистки от фенолов - 99%, от роданидов - 90-99%.In order to accelerate the biochemical treatment of wastewater containing phenols and rhodanides, iron salts, such as ferrous sulphate, in an amount of 10-40 g / m of wastewater are introduced into the wastewater before the biochemical treatment. The cleaning time is reduced to 15-20 hours. The degree of purification from phenols - 99%, from the Rodanides - 90-99%.

Пример. В сточную воду коксохимического производства, содержащую фенолы и роданиды , охлажденную до 28-32°С и усредненную , ввод т фосфорное питание и сернокислое железо, в количестве 10-40 г/м сточной воды (в пересчете на железо 2-8 мг/л), и подвергают биохимической очистке в аэротенке . рН сточной воды 7-8. Врем  биохимического окислени  15-20 час. Степень очистки от фенолов -99%, от роданидов - 90-99%.Example. Phosphoric nutrition and ferrous sulphate in the amount of 10-40 g / m of waste water (in terms of iron 2-8 mg / l are introduced into waste water of coke-chemical production, containing phenols and rhodanides, cooled to 28-32 ° C) and averaged. ), and subjected to biochemical purification in the aeration tank. The pH of the wastewater is 7-8. The biochemical oxidation time is 15-20 hours. The degree of purification from phenols -99%, from the Rodanides - 90-99%.

Очищенную сточную воду, соде)ржащую железо , используют в замкнутом цикле водоснабжени , в частности, дл  тушени  кокса, дл  гранул ции доменного шлака и т. д.Purified wastewater, soda iron, is used in a closed cycle of water supply, in particular, for quenching coke, for granulating blast-furnace slag, etc.

Предмет изобретени Subject invention

СпосОб очистки сточных вод от фенолов и роданидов охлаждением, усреднением, введением фосфорного питани  с последующим биохимическим окислением, отличающийс  тем, что, с целью ускорени  очистки, в сточную воду перед биохимическим окислением ввод т соли железа, например, сернокислое железо, в количестве 10-40 г/м сточной воды.A method of treating wastewater from phenols and rodanides by cooling, averaging, introducing phosphorus nutrition, followed by biochemical oxidation, characterized in that, in order to speed up the purification, iron salts, such as iron sulfate, are introduced into wastewater before biochemical oxidation. 40 g / m waste water.
