Embodiment 1

[0111] According to the liquid level of the dilute wastewater regulating tank, use the lifting pump to balance the wastewater to the facultative pool, control the pH of the incoming water at 11±1, turn on the return pump to control the return water ratio of 1.5:1, and adjust the air volume of the fan to make the facultative pool in the facultative state State, control DO concentration: 0.1-0.5mg / L, MLSS concentration: 3000-4000 mg / L, ORP: -50-+50mv. Set up a sedimentation area before the first-level aerobic upflow of wastewater to the outlet to reduce the loss of microorganisms in the aerobic effluent.

[0112] The effluent from the facultative tank then enters the primary aerobic tank, where the aerobic bacteria in the activated sludge are used to complete the degradation of organic matter. Adjust the gas volume to control the DO concentration in the primary aerobic pool: 2.0-5.0 mg / L, and the MLSS concentration: 2000-3000 mg / L. After the primary aerobic tank, a separate sed...

Abstract

The invention discloses a system for treating DCP waste water. The system comprises: a first-stage facultative anaerobic tank used for performing first-stage facultative anaerobic biochemical treatment to the DCP waste water; a first-stage aerobic tank used for performing first-stage aerobic biochemical treatment to the effluent of the first-stage facultative anaerobic treatment; optionally a catalytic oxidation tank used for performing catalytic oxidation treatment to the effluent of the first-stage aerobic treatment; and a second-stage biochemical tank used for performing second-stage biochemical treatment to the effluent of the first-stage aerobic tank or the effluent of the catalytic oxidation treatment if the catalytic oxidation tank exists. By adoption of the system, the DCP waste water can be effectively treated without secondary pollution of H2S.

Description

technical field [0001] The invention relates to a treatment method and a treatment system for fine chemical production wastewater, and more particularly to a treatment method and a treatment system for dicumyl peroxide (DCP) production wastewater. Background technique [0002] DCP is an organic peroxide crosslinking agent, mainly used as a crosslinking agent for various olefin polymers and copolymers (such as polyethylene, chlorinated polyethylene, silicone rubber, etc.) and a polymerization initiator for polystyrene , It can also be used as curing agent for unsaturated polyester resin. After DCP is crosslinked, the physical properties of the polymer are greatly improved, and the heat resistance, chemical resistance, pressure resistance, crack resistance and mechanical strength are all increased. DCP is widely used in wire and cable, shoemaking, building materials and other industries. In recent years, with the continuous expansion of the polymer material market, the demand...
