Description
Technical field
The present invention relates to the processing method of a kind of leather sewage, belong to technical field of sewage.
Background technology
Process and in purification of water quality at leather sewage, coagulation is one of them very important unit, it is to change the state of particulate matter in water by coagulant, the suspension composition in water and colloid composition is made to depart from, being formed under certain conditions can the precipitated or flco of dissolved air flotation, then by precipitation or air supporting, make this part flco separately.In coagulating treatment, the coagulant used for different types of sewage is the key processed, a lot of research worker is the most also had actively to research and develop new composite coagulant or flocculant, and the various coagulant of existing process leather sewage mainly or use iron salt or aluminium salt, do not do well differentiation for leather sewage；In sewage disposal, complex process is also a significant element simultaneously, there are some problems of compounding time and consumption on complex process, such as during processing leather sewage, exist for coagulant and leather sewage react slow and coagulant not with the problem such as the float in water reacts, causing the metallic element in coagulant to remain in water, create secondary pollution, the reaction of coagulant is incomplete simultaneously, also create the waste of coagulant, further increase the expense of sewage disposal.
Summary of the invention
It is an object of the invention to, it is provided that a kind of new leather sewage processing method.Utilize the method for the present invention to process leather sewage with coagulant, there is good sewage processing effect, coagulant reaction fully, advantages such as residuals is few, medicament usage amount is little in water
Technical scheme: the processing method of a kind of leather sewage, in being included in sewage conduct or exit adds coagulant by medicine spraying tube road, the method is to connect at least 1 additional pipeline on medicine spraying tube road, in coagulant, the complex element (or referred to as compound substance) for improving coagulant efficiency is added, in complex element enters sewage conduct after mixing with coagulant or in the sewage in exit by additional pipeline；Described coagulant is bodied ferric sulfate, aluminium polychlorid diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine copolymer；Described complex element is calcium chloride, magnesium chloride, magnesium sulfate, zinc sulfate, zinc chloride, phosphoric acid, sulphuric acid, hydrochloric acid, activated silicic acid, diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine copolymer.
Above-mentioned leather sewage processing method is, the time that complex element mixes with coagulant is less than 7 seconds, then enters back in the sewage in sewage conduct or exit.
Above-mentioned leather sewage processing method is, the time that complex element mixes with coagulant is 2～6 seconds, then enters back in the sewage in sewage conduct or exit.
Above-mentioned leather sewage processing method is, often adds 1000 parts of coagulant by mass parts, and the corresponding complex element that adds is 0.5～100 part.
Aforesaid leather sewage processing method is, often adds 1000 parts of coagulant by mass parts, and the corresponding complex element that adds is 0.5～20 part.
Aforesaid leather sewage processing method is, often adds 1000 parts of coagulant by mass parts, and the corresponding complex element that adds is 0.5～10 part.
Compared with the prior art, utilize the method for the present invention to process leather sewage with coagulant, there is good sewage processing effect, coagulant reaction fully, advantages such as residuals is few, medicament usage amount is little in water.
Applicant finds in long-term practice with test, after coagulant mixes with the complex element of various compositions, i.e. produce the inorganic polymer of a kind of more high polymerization degree, complex element refers to the various medicament that can improve coagulant effect, but in course of reaction, inorganic polymer form is only capable of to be stablized in a short period of time, extend in time, the inorganic polymer that can make high polymerization degree progressively returns to original coagulation form, therefore complex element puts into mixing in coagulant, to putting into the time of reaction in sewage, need in seconds to complete.Accordingly, applicant uses and properly mixed coagulant and complex element is separated input, reaches the effect of optimal coagulation when forming the inorganic polymer form of high polymerization degree with complex element after coagulant mixes with waste water.Use such method can reduce the consumption of coagulant 1/3, make again the float in coagulant and sewage and glial response more complete, coagulant uses more thorough, reduces coagulant and remains in water, it is to avoid the secondary pollution to water quality.Corresponding all kinds of sewage are repeatedly tested by the applicant always according to the method simultaneously; have found the process leather sewage optimal coagulant of institute and complex element; and most suitable proportion relation; so while solving problem of environmental pollution, decrease processing cost; and the leather sewage after processing also can be utilized by secondary; further save fund and Water Energy, protect environment, there is good economic benefit and social benefit.
Detailed description of the invention
Embodiments of the invention, because of different types of coagulant such as bodied ferric sulfate, aluminium polychlorid diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine copolymer；Can react at short notice during mixing, form inorganic polymer form, coagulant the most of the present invention and complex element (or compound substance) can be called allied substances, but identical material can not be used as coagulant and complex element at drug feeding pipeline and additional pipeline in specifically used simultaneously.
The blow-off line of the leather sewage of flowing arranges a drug feeding pipeline, an additional pipeline is connected in the side of drug feeding pipeline, adding coagulant by drug feeding pipeline, the coagulant added is that bodied ferric sulfate is alternatively aluminium polychlorid diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine copolymer.And adding complex element by tube-carrier, the complex element added is that calcium chloride is alternatively magnesium chloride, magnesium sulfate, zinc sulfate, zinc chloride, phosphoric acid, sulphuric acid, hydrochloric acid, activated silicic acid, diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine copolymer.null1000 parts of bodied ferric sulfates are often added by drug feeding pipeline by mass parts、Aluminium polychlorid、Diallyldimethylammonium chloride、Diallyldimethylammonium chloride or acrylic amine copolymer，Corresponding adds 2 parts of calcium chloride by additional pipeline、Magnesium chloride、Magnesium sulfate、Zinc sulfate、Zinc chloride、Phosphoric acid、Sulphuric acid、Hydrochloric acid、Activated silicic acid、Diallyldimethylammonium chloride、Diallyldimethylammonium chloride or acrylic amine copolymer，The coagulant added mixes in 7 seconds bottom drug feeding pipeline with complex element，Form inorganic polymer form，And contact with the leather sewage flowed rapidly，Medicament is diffused in leather sewage the most uniformly，After being fully hydrolyzed，The process to leather sewage can be completed，Leather sewage after processing is tested，It goes out water ph value、COD value is all up to national standard，And the leather sewage after Chu Liing also can utilize by secondary，Save fund and Water Energy，There is 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 render in leather sewage and complete the chemical reaction in leather sewage processing procedure.It is not limited in throwing in coagulant and complex element, as long as disclosure satisfy that above-mentioned requirements, it is possible to use other dosing mode by drug feeding pipeline and additional pipeline.
