Abstract
The invention discloses a kind of processing methods of commercial metal waste water, including setting pot, conditioning tank, comprehensive pool, buffer pool, secondary settling tank, MBR processing pond, sterilization pool, incinerator.This method comprehensive pool is original creation design, physical technology is used completely, including condensation, absorption, evaporation, the techniques such as aeration, using absorbing column as main processing units, heavy metal is to be diffused into electrostatic attraction or physically under the action of filler surface adsorption capacity the surface of filler first in solution, simple physical absorption occurs, further internally hole is spread, and generates stable complex with complexings such as the oxygen-containing functional groups in filler such as carboxyl, hydroxyl, achievees the effect that heavy metal resolution processing by this process.
Description
Technical field
A kind of processing method of commercial metal waste water of the present invention, belongs to the field of waste water treatment in environmental protection.
Background technique
China's heavy metal pollution of water body problem is very prominent, and the pollution rate of river,lake and reservior substrate is up to 80.1%.Huang in 2003
The pollution level in river, Huaihe River, Song Hua River, the basin piece heavy metal section of excess standard of ten large watershed such as Liaohe River is to surpass V class.2004
Total copper in year bottom mud in Taihu Lake, total lead, total cadmium content are in slight pollution level.The super back of Cd in the main stream of Huangpu River surface deposit
2 times of scape value, Pb surpasses 1 times, and Hg content obviously increases；Pb is all exceeded in Suzhou River, and Cd is 75% exceeded, and Hg is 62.5% exceeded.
Urban river has 35.11% section total mercury occur more than surface water Group III water body standard, and the total cadmium of 18.46% stream cross section is more than
III class water body standard, 25% section have the exceeded sample of total lead to occur.Huludao City Wujintang reservoir molybdenum polution problem is serious,
13.7 times of the overproof value of molybdenum concentration highest.By the Changjiang river, the Zhujiang River, the rivers such as the Yellow River are carried is about into extra large heavy metal contaminants total amount
3.4 ten thousand t are huge to the contamination hazard of ocean water body.
The method of heavy metal containing wastewater treatment can be substantially divided into three categories: (1) chemical method；(2) physical treatment process；(3) raw
Object facture.Chemical method mainly includes chemical precipitation method and electrolysis method, is primarily adapted for use in effluent containing heavy metal ions containing higher concentration
Processing, chemical method be at present both at home and abroad processing heavy metal-containing waste water main method.Physical treatment process mainly includes solvent extraction
Take separation, ion-exchange, membrane separation technique and absorption method.Biological treatment be by the flocculation of microorganism or plant, absorption,
The methods of the method, including biological adsorption, bioflocculation, phytoremediation of the effects of accumulation, enrichment removal heavy metal in waste water.
The treatment process for using Japan to provide substantially in heavy metal-containing wastewater treatment is applied at present, it is mainly by vulcanizing treatment
Process, gypsum neutralization step, iron salt oxidization process step combinations form.Although the group technology can make that treated water row up to standard
It puts, but also has deficiency:
1, it is generated in a large amount of sludge during this and contains hydrogen sulfide gas, it is past due to the removal rate in order to guarantee heavy metal
Toward needing to add excessive sulfide, excessive sulfide can generate hydrogen sulfide gas in acid condition, and hydrogen sulfide gas is
Severe toxicity is easy to generate personal injury to Field Force.2, the heavy metal sulfide generated is very subtle, and mud granule is fine and smooth, takes off
Water is difficult.3, contain a large amount of arsenic in sludge, heavy metal ion such as copper etc., if cannot handle in time, sewage sludge waste slag can occur
Diafiltration makes heavy metal permeate the ground in water body, causes secondary pollution problem .4, raw material and the quantity of slag very big, causes material transportation tired
Difficulty, lime stone pre-processing device is huge, takes up a large area；5, the intensity for generating gypsum is inadequate, containing noxious materials such as heavy metals,
So that gypsum is difficult to be utilized, the waste of resource is caused.6, water outlet be high saline sewage, can not reuse, affect the total of waste water
Recovery utilization rate.7, water processing establishment equipment is huge, and the water treatment system being composed is very huge many and diverse.
Summary of the invention
To solve the deficiencies in the prior art, the present invention provides a kind of processing method of commercial metal waste water,
It is characterized in that, the heavy metal-containing waste water in industrial processes is discharged into the water inlet of setting pot by pipeline connection, sink
The water outlet in sand pond connects the water inlet of conditioning tank by pipeline, and the water outlet of conditioning tank enters water by pipeline connection comprehensive pool
Mouthful, the water outlet of comprehensive pool passes through the water inlet of pipeline Connection Pool, and the water outlet of buffer pool connects secondary settling tank by pipeline
Water inlet, the water outlet of secondary settling tank connects the water inlet of MBR processing pond by pipeline, and the water outlet of MBR processing pond passes through pipe
Road connects the water inlet of sterilization pool, and the water outlet of sterilization pool connects discharge tube, and the discharge port of comprehensive pool is burnt by pipeline connection
Burn the feeding inlet of furnace；Wherein, comprehensive pool includes crusher, grinder, material delivery pipe, valve, absorbing column, central axis, aeration
Mouth, air-introduced machine, conveyer belt, resistive heater, scraping wings, drain spout, discharge port, water outlet, water inlet, air intake, appendix,
Water tank, air cooling equipment, aqueduct etc.；Wherein: crusher body is located at the top of pond body in comprehensive pool, and crusher entrance, which opens wide, to be located at
Outside pond body, crusher exports the entrance for being directly connected to grinder, is equipped with multiple groups absorbing column, equispaced side by side in the middle part of pond body
