Description
Technical field
The utility model relates to sewage treatment area, particularly a kind of coking wastewater processing system.
Background technology
Coking chemical waste water is the waste water in gas production, coking, metallurgy and ceramic kiln burning production process, due to coking chemical waste water water-quality constituents more complicated, organic pollutant and ammonia-nitrogen content higher, simultaneously also containing sulphur cyanides, belong to one of difficult waste water.The ubiquitous treatment effect of coking chemical waste water of the prior art is undesirable, cannot the shortcoming such as qualified discharge.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of stable, coking wastewater processing system that effluent quality is good.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of coking wastewater processing system, is characterized in that: comprise connect successively grid, equalizing tank, air-flotation system, water collecting basin, UBF anaerobic system (upflow sludge blanket-strainer), A/O reactive system, MBR pond, nanofiltration membrane separation device, produce pond; Described air-flotation system is provided with chemicals dosing plant, and described product pond is connected with clorox adding set; Nanofiltration membrane molecular weight cut-off in described nanofiltration membrane separation device is 150-300 dalton.
Preferably, described UBF anaerobic system outlet conduit is connected with one first reflux line be connected with water collecting basin.
Preferably, described MBR pond is connected with one second reflux line to be connected with the Aerobic Pond in A/O reactive system.
Preferably, connect a sludge thickener bottom described MBR pond, described sludge thickener connects between sludge dewatering.
Preferably, the medicament in described chemicals dosing plant is ferrate.
Adopt technique scheme, coking wastewater processing system described in the utility model, the combined system technique of being sterilized by air supporting+UBF+A/O+MBR+ carries out Treatment of Coking Effluent, and the coking chemical waste water after process can be made to meet reuse requirement, and have stable, the advantages such as processing cost is low.
Accompanying drawing explanation
Fig. 1 is coking wastewater processing system structural representation described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, coking wastewater processing system described in the utility model, comprise be connected successively with coking chemical waste water collecting tank grid 1, equalizing tank 2, air-flotation system 3, water collecting basin 4, UBF anaerobic system 5, A/O reactive system 6, MBR pond 7, nanofiltration membrane separation device 8, produce pond 13; Described air-flotation system 3 is provided with chemicals dosing plant 9, and described product pond 13 is connected with clorox adding set 12; Connect a sludge thickener 10 bottom MBR pond 7, described sludge thickener 10 to connect between sludge dewatering 11, and the nanofiltration membrane molecular weight cut-off in nanofiltration membrane separation device 8 is 150-300 dalton.
During concrete use, coking chemical waste water, after collecting, enters equalizing tank, is the comprehensive collecting pond of each workshop section discharge of wastewater, plays homogenizing water quality, water yield effect by equalizing tank after grid process; Waste water in equalizing tank enters air-flotation system, remove amount of grease, SS and CODcr, ferrate is added in air-flotation system, sulfide in further removal waste water, after air-flotation process, enters waste water after water collecting basin is collected, enter UBF anaerobic system, when in UBF anaerobic system, waste water passes through bed body with flow lifting type, contact reacts continuous with the carrier being attached with anaerobe film in bed, reaches organic object in anaerobic reaction decomposition, absorption effluent; After the process of UBF anaerobic system, waste water enters A/O reactive system, while carrying out denitrogenation, also degrade the organism such as phenol, cyanogen, COD, after A/O reaction system, waste water enters in MBR pond and processes, membrane sepn makes microorganism be dammed in bio-reactor completely, make can maintain higher microorganism concn in system, the product water in last MBR pond enters in nanofiltration membrane separation device and carries out nanofiltration separation, and nanofiltration membrane separation produces water can direct reuse after sterilization.
As optimal way, UBF anaerobic system 5 outlet conduit is connected with one first reflux line 13 and is connected with water collecting basin 4, make the waste water of part after the process of UBF anaerobic system return water collecting basin, carry out UBF anaerobic system again, improve treatment effect.MBR pond 7 is connected with one second reflux line 14 to be connected with the A pond (Aerobic Pond) 61 in A/O reactive system 6; Make the dense water of part in MBR pond 7 return to A pond 61, carry out A/O reaction again, improve treatment effect.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
