High-efficiency oil removal and turbidity removal device and oil-containing and turbidity-containing wastewater treatment process

Abstract

The invention discloses a high-efficiency oil removal and turbidity removal device. The high-efficiency oil removal and turbidity removal device has an integrated tank body structure; a water inlet mixing reactor and a clarifying device are arranged at the upper part of the tank body; a sludge collecting and discharging device is arranged at the middle part of the tank body; a filter and a backwashing system are arranged at the lower part of the tank body. According to the device, a chemical oil removal device and a high-speed filter are integrated; a hot water tank and a conveying pump are not required to be matched; the occupied area is small; the project investment is greatly reduced; the operating cost is reduced. The device integrates the functions of coagu-flocculation reaction, clarification and sedimentation, sludge discharging, filtering, backwashing and the like; the operating, backwashing and sludge discharging processes of the system is controlled by a PLC by matching an full-automatic control system; the operating, sludge discharging and backwashing processes of all pieces of equipment can be completed by operating on a matched control of the equipment; the operation is convenient; the automation degree is high; the water outlet quality is higher than a technical standard requirement.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a high-efficiency oil and turbidity removal device and a process for treating oily and turbid wastewater. Background technique [0002] For the oily and turbid waste water produced in the continuous casting and hot rolling workshops of iron and steel enterprises, two sets of independent devices, a chemical degreaser and a high-speed filter, are usually used in series for water treatment at present. A thermal pool acts as an intermediate pool. The water treatment process has many supporting equipment and occupies a large area, and the long-term operation of the pump consumes a lot of energy, which increases the cost of operation. The chemical degreaser has a large volume and must be assembled and welded on site, and the on-site construction period is long. The inside of the square mud storage hopper is prone to dead corners, and the mud discharge is not complete...
