Description
Technical field
The present invention relates to a kind for the treatment of process of leather sewage, belong to technical field of sewage.
Background technology
In leather sewage process and purification of water quality, coagulation is one of them very important unit, it is the state being changed particulate matter in water by coagulating agent, suspension composition in water and colloid composition are departed from, being formed under certain conditions can the flco of precipitated or dissolved air flotation, then by precipitation or air supporting, make this part flco separately.In coagulating treatment, the coagulating agent used for dissimilar sewage is the key processed, therefore a lot of researchist is had to develop new composite coagulant or flocculation agent in active research in addition, and the various coagulating agent of existing process leather sewage mainly still use molysite or aluminium salt, do not do good differentiation for leather sewage; In sewage disposal, complex process is also a significant element simultaneously, there are some problems of composite time and consumption on complex process, such as in process leather sewage process, with regard to exist coagulating agent and leather sewage react slow and coagulating agent not with the problem such as the suspended substance in water reacts, cause the metallic element in coagulating agent to remain in water, create secondary pollution, the reaction of coagulating agent is incomplete simultaneously, also create the waste of coagulating agent, further increase the expense of sewage disposal.
Summary of the invention
The object of the invention is to, a kind of new leather sewage treatment process is provided.Utilize method of the present invention and coagulating agent process leather sewage, there is good sewage processing effect, the advantages such as in coagulating agent sufficient reacting, water, residuals is few, medicament usage quantity is little
Technical scheme of the present invention: a kind for the treatment of process of leather sewage, be included in sewer line or exit adds coagulating agent by medicine spraying tube road, the method connects at least 1 additional pipeline on medicine spraying tube road, in coagulating agent, adding the complex element (or being called compound substance) for improving coagulating agent efficiency by additional pipeline, entering after complex element mixes with coagulating agent in sewer line or in the sewage in exit; Described coagulating agent is bodied ferric sulfate, polymerize aluminum chloride diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine multipolymer; Described complex element is calcium chloride, magnesium chloride, magnesium sulfate, zinc sulfate, zinc chloride, phosphoric acid, sulfuric acid, hydrochloric acid, activated silicic acid, diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine multipolymer.
Above-mentioned leather sewage treatment process is that the time that complex element mixes with coagulating agent is less than 10 seconds, and then enters in the sewage in sewer line or exit.
Above-mentioned leather sewage treatment process is, the time that complex element mixes with coagulating agent is 4 ~ 7 seconds, and then enters in the sewage in sewer line or exit.
Above-mentioned leather sewage treatment process is, often adds 1000 parts, coagulating agent by mass parts, and it is 0.5 ~ 100 part that correspondence adds complex element.
Aforesaid leather sewage treatment process is, often adds 1000 parts, coagulating agent by mass parts, and it is 0.5 ~ 20 part that correspondence adds complex element.
Aforesaid leather sewage treatment process is, often adds 1000 parts, coagulating agent by mass parts, and it is 0.5 ~ 10 part that correspondence adds complex element.
Compared with the prior art, utilize method of the present invention and coagulating agent process leather sewage, there is good sewage processing effect, the advantages such as in coagulating agent sufficient reacting, water, residuals is few, medicament usage quantity is little.
Applicant finds in long-term practice with test, after coagulating agent mixes with the complex element of various composition, namely a kind of inorganic polymer of more high-polymerization degree is produced, complex element refers to the various medicament that can improve coagulating agent effect, but in reaction process, inorganic polymer form only can be stabilized in the very short time, extend in time, the inorganic polymer of high-polymerization degree can be made progressively to return to original coagulation form, therefore complex element is dropped in coagulating agent the time being mixed to and dropping into and react in sewage, need in seconds to complete.Accordingly, applicant adopts properly mixed coagulating agent and complex element to separate and throws in, coagulating agent to mix with complex element form the inorganic polymer form of high-polymerization degree afterwards time and waste water reach the effect of optimal coagulation.Adopt such method can reduce the consumption of coagulating agent 1/3, make again the suspended substance in coagulating agent and sewage and glial response more complete, coagulating agent uses more thorough, reduces coagulating agent and remains in water, avoid the secondary pollution to water quality.The applicant also tests corresponding all kinds of sewage repeatedly according to the method simultaneously; have found the process leather sewage optimal coagulating agent of institute and complex element; and most suitable proportion relation; processing cost is decreased like this while solving problem of environmental pollution; and also can second stage employ to the leather sewage after process; further save fund and Water Energy, protect environment, there is good economic benefit and social benefit.
Embodiment
Embodiments of the invention, because different types of coagulating agent is as bodied ferric sulfate, polymerize aluminum chloride diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine multipolymer; Can react at short notice during mixing, form inorganic polymer form, therefore coagulating agent of the present invention and complex element (or claiming compound substance) can be allied substances, but identical material can not be used as coagulating agent and complex element at drug feeding pipeline 2 and additional pipeline 3 in concrete use 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, add coagulating agent by drug feeding pipeline, the coagulating agent added is that bodied ferric sulfate also can be polymerize aluminum chloride diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine multipolymer.And adding complex element by tube-carrier, the complex element added is that calcium chloride also can be magnesium chloride, magnesium sulfate, zinc sulfate, zinc chloride, phosphoric acid, sulfuric acid, hydrochloric acid, activated silicic acid, diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine multipolymer.1000 parts of bodied ferric sulfates are often added by drug feeding pipeline by mass parts, polymerize aluminum chloride, diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine multipolymer, corresponding adds 2 parts of calcium chloride by additional pipeline, magnesium chloride, magnesium sulfate, zinc sulfate, zinc chloride, phosphoric acid, sulfuric acid, hydrochloric acid, activated silicic acid, diallyldimethylammonium chloride, diallyldimethylammonium chloride or acrylic amine multipolymer, the coagulating agent added and complex element mix in 10 seconds bottom drug feeding pipeline, form inorganic polymer form, and contact with the leather sewage of flowing rapidly, medicament is diffused into rapidly in leather sewage uniformly, after abundant hydrolysis, the process to leather sewage can be completed, leather sewage after process is tested, it goes out water ph value, COD value all can reach national standard, and the leather sewage after process also can second stage employ, save fund and Water Energy, there is good economic benefit and social benefit.
Main points of the present invention are after being mixed with complex element by properly mixed coagulating agent, within the regular hour, to render to fast in leather sewage and the chemical reaction completed in leather sewage treating processes.Be not limited in and throw in coagulating agent and complex element by drug feeding pipeline and additional pipeline, as long as can above-mentioned requirements be met, also can adopt other dosing mode.
