Description
Technical field
The present invention relates to a kind of processing methods of leather sewage, belong to technical field of sewage.
Background technology
In leather sewage processing and purification of water quality, coagulation is one of them very important unit, it is to pass through coagulation
Agent changes the state of particulate matter in water, so that suspension sexual element and colloid composition in water is detached from, being formed under certain conditions can
It is deposited or the flco of dissolved air flotation makes this part flco separate then by precipitation or air supporting.In coagulating treatment, for
Coagulant used in different types of sewage is the key that processing, therefore has many researchers to be opened in positive research
The composite coagulant or flocculant for sending out new, and the various coagulant of existing processing leather sewage mainly still use molysite
Or aluminium salt, there is no do good differentiation for leather sewage；Complex process is also an important list in sewage disposal simultaneously
Member, on complex process on there are problems that compounding time and dosage some, such as during handling leather sewage, just
There are coagulant to react slow with leather sewage and the problems such as coagulant does not react with the suspended matter in water, lead to coagulant
In metallic element residual in water, produce secondary pollution, while the reaction of coagulant is incomplete, also creates coagulant
Waste, further increase the expense of sewage disposal.
Invention content
The object of the present invention is to provide a kind of new leather sewage processing methods.Utilize the method and coagulation of the present invention
Agent handles leather sewage, has a good sewage processing effect, and fully, in water residuals are few for coagulant reaction, pharmaceutical use is small
The advantages that
Technical scheme of the present invention：A kind of processing method of leather sewage, including in sewage conduct or exit passes through spray
Coagulant is added in pipeline, and this method is to connect at least one additional pipeline on spray pipeline, by additional pipeline in coagulant
The interior complex element (or being compound substance) being added for improving coagulant efficiency, after complex element is mixed with coagulant
In into sewage conduct or in the sewage in exit；The coagulant is bodied ferric sulfate, aluminium polychloride diallyl two
Ammonio methacrylate, diallyldimethylammonium chloride or acrylic amine copolymer；The complex element is calcium chloride, chlorination
Magnesium, magnesium sulfate, zinc sulfate, zinc chloride, phosphoric acid, sulfuric acid, hydrochloric acid, activated silicic acid, diallyldimethylammonium chloride, two allyls
Base alkyl dimethyl ammonium chloride or acrylic amine copolymer.
Above-mentioned leather sewage processing method is, the time that complex element is mixed with coagulant is less than 10 seconds, then again into
Enter in sewage conduct or the sewage in exit.
Above-mentioned leather sewage processing method is, the time that complex element is mixed with coagulant is 4~7 seconds, then again into
Enter in sewage conduct or the sewage in exit.
Above-mentioned leather sewage processing method is that 1000 parts of coagulant is often added by mass parts, corresponding that complex element is added
It is 0.5~100 part.
Leather sewage processing method above-mentioned is that 1000 parts of coagulant is often added by mass parts, corresponding that complex element is added
It is 0.5~20 part.
Leather sewage processing method above-mentioned is that 1000 parts of coagulant is often added by mass parts, corresponding that complex element is added
It is 0.5~10 part.
Compared with the prior art, leather sewage is handled with coagulant using the method for the present invention, there is wastewater treatment efficiency
Well, the advantages that coagulant reaction is fully, residuals are few, pharmaceutical use is small in water.
Applicant has found in long-term practice with experiment, after coagulant is mixed with the complex element of various composition, that is, produces
A kind of raw inorganic polymer of more high polymerization degree, complex element refers to the various medicaments that can improve coagulant effect, but anti-
During answering, inorganic polymer form can only be stablized in a short period of time, extend at any time, can make the nothing of high polymerization degree
Machine macromolecule is gradually restored to original coagulation form, therefore complex element is put into coagulant and is mixed into input sewage instead
The time answered needs to complete in seconds.Accordingly, applicant use by properly mixed coagulant with it is compound
Element is separately launched, and is connect with sewage when forming the inorganic polymer form of high polymerization degree after coagulant is mixed with complex element
It touches and achievees the effect that optimal coagulation.The dosage of coagulant 1/3 can be reduced using such method, and makes coagulant and dirt
Suspended matter and glial response in water is more complete, and coagulant utilization is more thorough, reduces coagulant residual in water, avoids
Secondary pollution to water quality.The applicant tests corresponding all kinds of sewage also according to this method repeatedly simultaneously, finds
The most suitable coagulant of processing leather sewage institute and complex element and most suitable proportion relation, are in this way solving environment
Reduce processing cost while pollution problem, and leather sewage can also secondary use, further section to treated
Fund and Water Energy have been saved, environment is protected, there is good economic benefit and social benefit.
Specific implementation mode
The embodiment of the present invention, because of different types of coagulant such as bodied ferric sulfate, aluminium polychloride diallyl dimethyl
Ammonium chloride, diallyldimethylammonium chloride or acrylic amine copolymer；It can react in a short time when mixing, shape
At inorganic polymer form, therefore coagulant of the present invention and complex element (or compound substance) can be congener
Matter, but can not use identical substance simultaneously as coagulant in drug feeding pipeline 2 and additional pipeline 3 in specifically used and answer
Close element.
One drug feeding pipeline is set on the blow-off line of the leather sewage of flowing, one is connected in the side of drug feeding pipeline
Coagulant is added by drug feeding pipeline in a additional pipeline, and the coagulant being added is that bodied ferric sulfate is alternatively aluminium polychloride
Diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine copolymer.And it is added by tube-carrier multiple
Close element, the complex element being added be calcium chloride be alternatively magnesium chloride, magnesium sulfate, zinc sulfate, zinc chloride, phosphoric acid, sulfuric acid,
Hydrochloric acid, activated silicic acid, diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine copolymer.By matter
1000 parts of bodied ferric sulfates, aluminium polychloride, diallyldimethylammonium chloride, diene are often added by drug feeding pipeline for amount part
Diallyidimethylammonium chloride or acrylic amine copolymer, it is corresponding that 2 parts of calcium chloride, magnesium chloride, sulfuric acid are added by additional pipeline
Magnesium, zinc sulfate, zinc chloride, phosphoric acid, sulfuric acid, hydrochloric acid, activated silicic acid, diallyldimethylammonium chloride, diallydimethyl
Ammonium chloride or acrylic amine copolymer, the coagulant being added and complex element are mixed in 10 seconds in drug feeding pipeline bottom, are formed
Inorganic polymer form, and be in contact with the leather sewage of flowing rapidly so that medicament is uniformly diffused into rapidly leather sewage
In, after being fully hydrolyzed, you can complete the processing to leather sewage, leather sewage is tested to treated, is discharged PH
Value, COD value up to national standard, and treated leather sewage can also secondary use, save fund and Water Energy,
With good economic benefit and social benefit.
The method is characterized in that after properly mixed coagulant is mixed with complex element, within the regular hour, quickly
It launches in leather sewage and completes the chemical reaction in leather sewage processing procedure.Be not limited in through drug feeding pipeline and
Additional pipeline launches coagulant and other dosing modes can also be used as long as disclosure satisfy that above-mentioned requirements in complex element.
