Abstract
The utility model relates to the technical field of waste water treatment in production of chemicals, in particular to a waste water treatment device in production of 4,4'-diaminodiphenyl ether and 4,4'-dinitrodiphenyl ether. The device adopts the technical scheme of integrating a pretreatment device and a biochemical treatment device, realizes effective treatment of the waste water to be treated with great difficulty, has low cost, recycles useful substances and further makes profits for enterprises.
Description
Technical field
The utility model belongs to the technical field of Chemicals production wastewater treatment device, be specifically related to a kind of 4,4-diaminodiphenyl oxide and 4, the wastewater treatment equipment during the 4-dinitro diphenyl ether is produced.
Background technology
In recent years, along with domestic 4.4-diaminodiphenyl oxide, 4.4-dinitro diphenyl ether market is much more popular, domestic 4.4-diaminodiphenyl oxide, 4.4-dinitro diphenyl ether manufacturer scale is also along with increase, but at the 4.4-diaminodiphenyl oxide, the waste water during the 4.4-dinitro diphenyl ether is produced, principal pollutant are ammonia nitrogen, COD and suspended substance etc., waste discharge concentration of suspension height, the ammonia nitrogen concentration height, and COD concentration is lower, the imbalance of C/N nutritive props, contain in the sewage and be difficult to biochemical macromolecular substance, the biological treatment difficulty is big, belongs to highly difficult wastewater from chemical industry, can not directly carry out biochemical treatment.
The utility model content
The purpose of this utility model is to provide a kind of 4.4-diaminodiphenyl oxide at the defective of above-mentioned existence, 4.4-the treatment unit of dinitro diphenyl ether factory effluent, the technical scheme of the mode that this device employing pretreatment unit and biochemical treatment apparatus combine, realized effective processing of high-leveled and difficult waste water, and cost is low, also reclaimed useful matter, further created profit for enterprise.
The technical solution of the utility model is: a kind of wastewater treatment equipment, comprise the factory effluent relief outlet, it is characterized in that, described factory effluent relief outlet is linked in sequence successively and regulates preliminary sedimentation tank, micro cell, coagulative precipitation tank, air flotation pool, ammonia-nitrogen desorption tower, hydrolysis acidification pool, contact-oxidation pool, two settling tanks, and this two settling tank is provided with water outlet; Described adjusting preliminary sedimentation tank, micro cell, coagulative precipitation tank, air flotation pool, ammonia-nitrogen desorption tower, hydrolysis acidification pool, contact-oxidation pool and two settling tanks are connected sludge thickener respectively, this sludge thickener connects plate-and-frame filter press, and the supernatant liquor outlet of this sludge thickener connects regulates preliminary sedimentation tank; Described micro cell, air flotation pool connect chemicals dosing plant respectively; Described ammonia-nitrogen desorption tower connects cuvette; Described contact-oxidation pool connects gas blower.
The beneficial effects of the utility model are: wastewater treatment equipment of the present utility model
(1) lowered cost of sewage disposal.This waste water can be reduced to the running cost of ton water 5 yuan/ton below the water simultaneously through being to carry out biochemical treatment after certain pre-treatment.
(2) system stability improves.
(3) recycle ammoniacal liquor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein, 1 for regulating preliminary sedimentation tank, and 2 is micro cell, and 3 is coagulative precipitation tank, and 4 is air flotation pool, 5 is the ammonia-nitrogen desorption tower, and 6 is hydrolysis acidification pool, and 7 is contact-oxidation pool, and 8 is gas blower, and 9 is two settling tanks, 10 is chemicals dosing plant, and 11 is cuvette, and 12 is plate-and-frame filter press, and 13 is sludge thickener.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in detail.
As can be seen from Figure 1, wastewater treatment equipment of the present utility model, comprise the factory effluent relief outlet, described factory effluent relief outlet is linked in sequence successively and regulates preliminary sedimentation tank 1, micro cell 2, coagulative precipitation tank 3, air flotation pool 4, ammonia-nitrogen desorption tower 5, hydrolysis acidification pool 6, contact-oxidation pool 7, two settling tanks 9, and this two settling tank is provided with water outlet; Described adjusting preliminary sedimentation tank 1, micro cell 2, coagulative precipitation tank 3, air flotation pool 4, ammonia-nitrogen desorption tower 5, hydrolysis acidification pool 6, contact-oxidation pool 7 and two settling tanks 9 are connected sludge thickener 13 respectively, this sludge thickener 13 connects plate-and-frame filter press 12, and the supernatant liquor outlet of this sludge thickener 13 connects regulates preliminary sedimentation tank 1; Described micro cell 2, air flotation pool 4 connect chemicals dosing plant 10 respectively; Described ammonia-nitrogen desorption tower 5 connects cuvette 11; Described contact-oxidation pool 7 connects gas blower 8.
Wastewater treatment equipment working process of the present utility model is: factory effluent at first enters the adjusting preliminary sedimentation tank, carry out the adjusting of water quality and quantity, then from flowing to micro cell, from flowing into coagulative precipitation tank, air flotation pool, go out most suspended substance, squeeze into the ammonia-nitrogen desorption tower by pump again, the ammonia that stripping goes out is absorbed by cuvette.The water of process ammonia-nitrogen desorption flows automatically and carries out the anoxic denitrification processing into the hydrolysis acidification pool, flows into contact-oxidation pool again and carries out the aerobic nitrification processing, enters two settling tanks then and carries out mud-water separation, and two settling tank water outlets get final product qualified discharge.Excess sludge and body refuse that system discharges enter sludge thickener, after the mummification of plate-and-frame filter press filter-press dehydration, become mud cake, and directly landfill disposal is carried out in outward transport.
