COMPLEX FOR INDUSTRIAL DISCHARGES AND SEWAGE WATER TREATMENT Russian patent published in 2017 - IPC C02F9/12 C02F11/12 C02F1/48 B01D29/09 B01D29/96 

FIELD: chemistry.

SUBSTANCE: complex includes a housing with a capacity of (1), a transport-dewatering unit (5), three-type modular water purification devices (2, 3, 4), water supply (19) and discharge (10) devices. The capacity (1) of a triangular or trapezoidal section has an angle of sides inclination of 43-48° and is docked with the hulls of transport-dewatering units - horizontal (7) and inclined (8). Inside the case, modular water purification devices (2, 3, 4) of the same type are installed in pairs, separated by transverse partitions (6). The receiving section (9) is separated from modular "blinds" (2) devices by a partition (6) from the top to 2/3 of module height. Modular devices of thin-layer clarifiers (3) and modular devices for electrical water treatment (4) are separated by transverse partitions (6) from the bottom to 2/3 of modules height. The water discharge device (10) is separated from modular electrical processing devices (4) by a transverse partition (6) from the top. The transport devices (7) and (8) are pipes with slots in the sludge outlet vessel (1) and are docked at an angle of 8-13° with the screws (11) placed inside. The slot (14) of the transport-dewatering unit (5) is cut in the pipes from the partition separating the modular water treatment device (4) to the point of tank filling with water on an inclined pipe that has a tie sieve (15) on the upper end and a pan (16) with a discharge pipe (17) to discharge the sub-product into the container (1). The slot (14) is covered by a grid (18) made of plates installed at an angle of 45°. The water supply device has a flat bell (20), the water discharge device (10) has a pipe diameter that ensures flow rate of not more than 0.1 m/s in the complex.

EFFECT: complex provides reliability, design simplification and reduction of equipment dimensions.
