Description
Technical field
The invention belongs to sewage treatment area, be specifically related to a kind of sewage-treating agent.
Background technology
Sewage disposal is the water quality requirement making sewage reach a certain water body of draining or reuse, and to the process that it purifies.Sewage disposal is widely used in building, agricultural, and the every field such as traffic, the energy, petrochemical industry, environmental protection, urban look, medical treatment, food and drink, also come into the daily life of common people more and more.
By sewage source classification, sewage disposal is generally divided into production waste process and sanitary sewage disposal.Production waste comprises industrial sewage, rural sewage and medical sewage etc., and sanitary sewage is exactly the sewage that daily life produces, and refers to various forms of inorganics and organic complex mixture, comprising: the floating size solid particulate with suspending; Glue and gel diffusate; Pure solution.
Divide by the character of water pollutions, the pollution of water has two classes: a class is natural pollution; Another kind of is artifact pollution.Current larger to water body harm be artifact pollution.Water pollutions can mainly be divided into chemical contamination, physical pollution and biotic pollution three major types according to the difference polluting impurity.Pollutent mainly contains: one, unprocessed and discharge trade effluent; Two, unprocessed and discharge sanitary sewage; Three, the farmland sewage of chemical fertilizer, agricultural chemicals, weedicide is used in a large number; Four, trade waste and the domestic refuse of river bank is deposited in; Five, soil erosion; Six, mine system engineering etc.The method of disposing of sewage is a lot, generally can be summarized as Physical, chemical method and biological process etc.
Industrially generally in water coolant, add water conditioner reduce corrosion and fouling.For with higher hardness and basicity water (hardness or basicity >200mg/L, hardness or basicity are in CaCO3, be the cooling water system of make up water down together), though have more water treatment formula at present, subject matter is: the synergetic property of medicament is not obtained larger embodiment by the component 1) selected and component proportion; 2) selection of component does not embody the requirement of comprehensive scale inhibitor and stability effectively; 3) trend of environmental protection should be met, draining is accomplished without phosphorus or low-phosphorous, medicament low toxicity or nontoxic as far as possible; 4) low amounts and efficient principle should be embodied.
CN1258649 discloses a kind of Recompounded multielement antisludging corrosion inhibitor, includes machine phosphonic acid (4-15mg/l), containing sulfonic group multipolymer ((4-15mg/1), zinc salt (1.5-5mg/1) and the copper material corrosion inhibitor ((0.5-1.5mg/I) existed depending on particular case.Be suitable for using under cycles of concentration is the condition of 2.3 scholars 0.2.Due to factors such as environment, population and industrialization, the supporting capacity of water resources is faced with severe tests.Current process water accounts for about 70% of urban water consumption, and water coolant accounts for the 60-70% of process water.Cycles of concentration is an important indicator of recirculated water, and its size determines the level of water saving, determines the height of the repeating utilization factor of water.Therefore, while the anticorrosive and scale inhibition effect of guarantee water conditioner, cycles of concentration is improved to greatest extent thus water saving has meaning.
In modern industry recirculating cooling water system, traditional phosphorus system water conditioner is usually adopted to come fouling and the etching problem of Controlling System.But the calcium, magnesium ion etc. of phosphorus system water conditioner easily and in water coolant react and generates secondary incrustation scale, and incrustation scale skewness in systems in which; The phosphorus existed in system is that fungus algae provides nutrition source, makes fungus algae overpreading, creates biological clay, must use sterilant ability sterilization algae removal.The cooling waste water of system blowdown not only pollutes environment, and easily makes body eutrophication, produces red tide.Therefore, oneself becomes the important and urgent task of of current treatment of cooling water to replace phosphorus line formulation water conditioner.
Sodium salts humic acids is macromolecular compound, has the several functions such as demineralized water, antiscale, protection against corrosion and scale removal, and Sodium salts humic acids low price, nontoxic, chemical stability is good, can deposit use for a long time.Sodium salts humic acids is a kind of well scale remover, the scale effect mechanism of Sodium salts humic acids is not merely calcium, magnesium ion are stabilized in water, but generate grain slag, do not form hard scale, scale inhibition effect is reached by blowdown, at this moment calcium, magnesium ion concentration change contains the grain slag amount that a part does not generate incrustation scale, and Sodium salts humic acids also can be adsorbed on metallic surface, prevents fouling.So Sodium salts humic acids is the inevitable requirement of industry as scale remover, but the corrosion inhibition of Sodium salts humic acids is not very desirable.Show according to survey data, the fault of boiler tube boiler makes equipment availability reduce by 3%.In the fault in power station, boiler failure can account for more than 70%.And in boiler failure based on the explosion of economizer, superheater and water wall, leak.Abrasion and corrosion is the major cause of explosion, leakage.The generating set of current China is just developing into subcritical, supercritical pressure generating units, if do not take some countermeasures to the etching problem of heat power equipment, unit is just difficult to safe operation.So a kind of inhibiter that can be composite with Sodium salts humic acids must be found, by this inhibiter and Sodium salts humic acids compound use, reach the scale removal to carbon steel and inhibition double effects.
CN201310104465 discloses a kind of water conditioner containing inhibiter, comprise Sodium salts humic acids and inhibiter, described inhibiter is made up of water glass, sodium oleate, Sodium dodecylbenzene sulfonate and hexamethylenetetramine, in often liter of pending water, the add-on of each component is Sodium salts humic acids 0.025g, water glass 0.1-2g, sodium oleate 0.02-2g, Sodium dodecylbenzene sulfonate 0.1-2g, hexamethylenetetramine 0.05-2g, is 8.0-9.0 with sodium hydroxide adjust pH.Although the problem that the Sodium salts humic acids corrosion inhibition that this formula solves is undesirable, the effect of sterilization is not very desirable.
