SYSTEM OF WASTE WATERS ZERO WASTE DISPOSAL

摘要

FIELD: water supply.SUBSTANCE: invention relates to domestic waste water processing, namely, to system of waste waters zero waste disposal with their desalination and further supply to injection into gas transfer units gas-turbine plants for cooling of turbines. Waste water recycling system includes waste water biological or biochemical treatment unit (4), having treated effluent (14) outlet and sediment (20) outlet, sediment (20) composting unit (5), connected to sediment outlet, evaporation unit (7) for treated effluent (14) desalination, connected to treated effluent (14) outlet and having desalinated water (15) supply outlet and blowdown water (21) outlet, settling-crystallization unit (8) connected to blowdown water (21) outlet. At that, evaporation unit (7) desalinated water (15) supply outlet is made with possibility of communication with gas compressor unit gas turbine plant (10) cooling device (GCU GTP), installed with possibility of desalinated water injection into GCU GTP (10) path.EFFECT: technical result is minimization of ambient environment pollution due to absence of recycling wastes, higher degree of waste water purification, decreasing power consumption for recycling, increasing in GCU GTP efficiency and power.8 cl, 1 dwg
