With requiring, a kind of desulfurization wastewater processing solution, the solution are provided, operating cost is significantly less than three traditional header works
Skill.
Background technique
Wet process of FGD is that sulphur atmosphere pollution handles a kind of mature, efficient sulfur removal technology, is widely used in various cigarettes
Desulfurization device；In order to maintain the balance of desulfurizer serum recycle system substance, soluble fraction i.e. cl concn in flue gas is prevented
More than specified value and guarantee gypsum quality, it is necessary to a certain amount of waste water is discharged from system, containing a large amount of in this effluent part
Suspended matter, calcium and magnesium hardness, activated silica, heavy metal, COD, sodium chloride, amount with high salt and other particular matters；For border on the sea or water money
Source place abundant is save the cost, and desulfurization wastewater is mostly through three header process to discharge or for rinsing at this stage
Ground etc..
But there is also some problems for three traditional header techniques:
(1) it is that the suspended matter in desulfurization wastewater is made to include the heavy metal precipitation object that dosing generates, can quickly settles,
PAC and PAM is added in three headers.But desulfurization wastewater is interim draining, and variation water quality is big, it is therefore desirable to according to the variation of water quality
PAC and PAM dosage is adjusted, just can achieve preferable flocculating effect, dosage is too little or too much all to reduce flocculating effect,
This is difficult to realize in managing at the scene, to cause the water quality being discharged after processing unstable.In addition, dosing flocculation system needs people to add
Medicine, the larger workload of equipment operation and maintenance.
(2) waste water through discharging after flocculation sedimentation, still contains certain suspended matter, and some is further added by a filter and sets
Standby, treated to the water outlet of flocculation sedimentation, this has accordingly increased cost, maintenance workload and occupied area.
Utility model content
The shortcomings that the purpose of this utility model is, overcomes the prior art, according to the characteristics of desulfurization wastewater and discharge of wastewater or
Reuse requirement, provides a kind of desulfuration waste water treatment process and equipment, operating cost are significantly less than other treatment process and equipment.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of desulfurization wastewater processing equipment, by water
Stream direction sequence is equipped with: with the wastewater collection pond of desulfurization wastewater water connection, preliminary sedimentation tank, circulating tank, elevator pump, silicon carbide film

Outlet be connected with the entrance of circulating tank, the bottom discharge port of preliminary sedimentation tank is connected with sludge pump, the entrance of sludge pump and dewaterer
It is connected, the mud cake outlet that dewaterer generates, pressing filtering liquid returns to preliminary sedimentation tank；The outlet of circulating tank is connected with elevator pump, elevator pump
It is connected with the water inlet of silicon carbide film separation equipment, the concentrated water of silicon carbide film separation equipment returns to preliminary sedimentation tank or/and circulating tank, carbon
The production mouth of a river of SiClx membrane separation plant passes through blowpipe and water producing tank.
A kind of desulfurization wastewater processing equipment, dewaterer use plate and frame filter press.
Utility model principle
Desulfurization wastewater is unable to direct emission, it is important to therefore can go in waste water containing heavy metal and a large amount of suspended matter
Removing heavy metals and suspended matter, desulfurization wastewater can discharge or for flushings etc..And silicon carbide film is that flux is big, tolerance is good
The membrane material material products of new generation of (full pH range is general), and there are the characteristics such as high, the wear-resistant, high temperature resistant of hardness, it can be effectively real
It is separated by solid-liquid separation under existing harsh environment.In order to achieve the above object, first converting solid hydroxide for most of heavy metal ion with alkali
Object, while solid sulfide is converted by mercury and cadmium with organic sulfur, waste water needs not move through flocculation, is directly entered silicon carbide film point
It from equipment, realizes and is separated by solid-liquid separation, obtain the flushing water for producing water or qualification of qualified discharge, and the concentrated water of silicon carbide film separation equipment
It is selected to return to circulating tank or/and preliminary sedimentation tank according to the content of suspended matter.
The major technique effect of the utility model is described as follows:
1, the technique of the utility model desulfurization wastewater processing equipment, equipment processing desulfurization wastewater is: desulfurization wastewater passes through
Pipeline flows into before preliminary sedimentation tank, adds lye and organic sulfur by pipeline mixing, the pH value of waste water is made to be increased to 9.0~9.5 left sides
The right side converts solid hydroxide for most of heavy metal ion, while converting solid-state for mercury and cadmium by organic sulfur
Sulfide.
After preliminary sedimentation tank carries out preliminary preliminary sedimentation, supernatant enters the boosted pump of circulating tank and is delivered to silicon carbide film separation equipment
Further it is separated by solid-liquid separation, the production water of silicon carbide film is outer defeated after acid adding adjusts back pH value, and the stoste of silicon carbide film is concentrated,
Continue to be back to circulating tank or/and preliminary sedimentation tank.
After preliminary sedimentation tank base sludge solid content reaches 3%, it is delivered to plate and frame filter press dehydration, plate compression by pump
The dewatered sludge outward transport of machine discharge, filtrate are back to preliminary sedimentation tank.
2, the silicon carbide film separation equipment in the utility model；Separation of solid and liquid can be realized under severe conditions, had logical
The characteristics such as amount big, tolerance good (full pH range is general), high, the wear-resistant, high temperature resistant of hardness.
In conclusion the principles of the present invention are the heavy metal in desulfurization wastewater with alkali and organic sulfur by ion conversion
It at solid particles, then realizes and is separated by solid-liquid separation through silicon carbide film separation equipment, obtain the flushing for producing water or qualification of qualified discharge
Water.The treatment process is simple, and equipment operation and energy consumption are very low.
