SYSTEM FOR PRELIMINARY PREPARATION OF INDUSTRIAL WASTES FOR BIOCHEMICAL TREATMENT

摘要

FIELD: chemistry. ^ SUBSTANCE: invention can be used in waste water treatment. Depending on the pH of the incoming liquid stream, a control device 3 brings an electromagnet 4 into a state where the core pulled in or not. Valve 6 turns such that liquid through flow distributor 5 on pipe 7 or 8 enters accumulation tank 9 or 10. Continuous liquid streams from containers 9 and 10 reach inputs of flow computer 13 through flow regulators 11 and 12 respectively. Treated waste water then passes through pipe 14 into biochemical filter 15 and to the output of the device. ^ EFFECT: invention simplifies and increases stability of controlling the given system, enables stabilisation of pH and component composition of waste water. ^ 3 cl, 2 dwg
