The low-phosphorous water treatment medicament is formed by compounding a scale inhibition and dispersion agent and a corrosion inhibitor with different proportions according to different water qualities, wherein under the condition of compounding, the weight percentage of a phosphorous acid (as calculated by PO4<3->) in the medicine is controlled to less than or equal to 4 percent, the solid content is controlled to more than or equal to 25 percent, and the content of an orthophosphorous acid is controlled to less than or equal to 0.2 percent. The whole set of technology comprises preparation of the medicament, addition of the medicament, and a control and detection device which is matched with the whole set of technology. The low-phosphorous water treatment medicament is simple to prepare and convenient to use, has moderate usage amount and low cost, can meet the discharge standards, and is suitable to be used on most of domestic circulating water systems.
Description
Technical field: the invention belongs to environmental protection technical field, relate to a kind of low-phosphorous water treatment agent of cycle of treatment water coolant and customize production technique and complete-set applied technology.
Background technology: China is a country of water resources famine per capita.In industry, industrial circulating cooling water is the water rich and influential family, all needs to use a large amount of recirculated water at aspects such as metallurgy, electric power, chemical industry, oil productions, and the scarcity of water resources has become an important factor of these industry developments of restriction.And in the recirculated water application process, can produce fouling, corrosion and situations such as bacterium algae, foundry loam growth, therefore must add a certain amount of water quality stabilizer, as corrosion inhibiting and descaling agent and sterilant.And corrosion inhibiting and descaling agent in the past often adopts all is inorganic phosphorus or organophosphorus prescription, these prescriptions are except solving the problem in the above-mentioned recirculated water, all can cause secondary pollution, most of discharging all can not meet the regulation of P in the sewage discharge, and want dephosphorization in sewage is the comparison difficulty, cost is also very high, therefore since the nineties from abroad beginning progressively at the research phosphate-free water treatment agent.(there are strict requirements: discharge of wastewater primary standard P＜0.5mg/L, secondary standard＜1.0mg/L to phosphorus discharging in China.) without phosphorus in addition prescription helps sterilization algae removal, because phosphorus also is the nutrition source of certain bacterium algae.
" a kind of is the composite water disposal agent of host with the poly aspartic acid " disclosed as Chinese patent CN1323750A; CN200310115070.3 discloses " a kind of non-Phosphorus composite anti incrustation eorrosion snhibiter that is used for the cycle of treatment water coolant " etc., the purpose of these inventions all wishes to find a kind of method that solves the phosphorus secondary pollution, but even to this day, really can be in actual production application success example seldom, and cost is very high, substantially do not have promotional value, thus at present domestic basically 98% or more device to be phosphine be to fill a prescription.
Summary of the invention: it is a kind of under the prerequisite that meets the phosphorus emission request that purpose of the present invention is exactly proposition, the low-phosphorous water treatment agent of cycle of treatment water coolant and customization production technique and complete-set applied technology, comprise all many-sides such as the control of treatment agent formula, water quality, medicament add, detect, application, really can accomplish efficient, low-phosphorous, easy production, easy to control, inexpensive in practice.
Low-phosphor water treatment agent of the present invention is such: its compound basis water quality different mining is with the dirt dispersion agent of different ratios and inhibiter is composite forms, and phosphonic acids is (with PO in the composite time control pharmacy agent
4 3-Meter) weight percentage≤4%, solid content 〉=25%, inferior phosphorus content≤0.2%; Dirt dispersion agent contains the 10%-30% multipolymer of weight percentage, its main component is oleic series, carboxyl, sulfonic polymkeric substance, submember is PBTCA (the 2-phosphonic acids butane-1 of weight percentage 5%-25%, 2,4-tricarboxylic acid), the mixture of one or more of PESA (poly-epoxy succinic acid), PASP (poly aspartic acid), poly-horse; Inhibiter contains the Sunmorl N 60S of weight percentage 0%-10%, the benzotriazole of 0%-1%, the tolyltriazole of 0%-1%, the molybdate of 0%-5%, the soluble tungstate salt of 0%-5% and the solubility ZnSO of 2%-10%

Treatment agent formula usually of the present invention can adopt the Orthogonal Method experiment to determine the best dosage of various monomers according to the water quality situation.Simultaneously for measurement of concetration accurately and convenient, also added the tracer agent of weight percentage 2% one 7%, as fluorescein etc.
Customization production of the present invention and complete-set applied technology are achieved like this: mainly comprise medicament prepares, medicament adds and match with it control and proofing unit; The medicament preparation is according to the composite processing medicament of said ratio, and the water quality situation of handling according to desire adopts the Orthogonal Method experiment to determine the best dosage of various monomers simultaneously; Medicament adds that the medicament that adopts automatization adds and concentration measurement system comes indexs such as Control Circulation water cycles of concentration, pH, concentration, and can detect and control the concentration that adds of medicament.
General the present invention adopts the cycles of concentration that automatic medicine adding apparatus can Control Circulation water, automatic pollution discharge and determine to add drug concentration according to tracer concentration; Detection is to demarcate medicament by measurement phosphine content to add concentration, measures concentration and can reach error in ± 5%.
The present invention is more obvious for the effect that makes water treatment, can adopt the method for ion bar electrical treating to assist realization corrosion-mitigation scale-inhibition sterilizing function.
Low-phosphor water treatment agent of the present invention and customized production thereof and complete-set applied technology are compared following advantage with without phosphorus or low-phosphorous prescription in the past: 1. low-phosphorous among the present invention is not the content that simply reduces some phosphorus, but in prescription, introduce new dirt dispersion agent and zinc salt stablizer, make that scale inhibition disperses to realize under low cost, can cooperate with zinc, molybdenum, tungsten plasma simultaneously to form the strong host of corrosion inhibition; 2. except that prescription, the present invention adopts control and measuring system automatically at aspects such as control, detections, have good operability and practical value; 3. use production technique of the present invention and complete-set applied technology, can reach environmental requirement, realize that on the basis of qualified discharge preparation is simple, easy to use, usage quantity is moderate, and the purpose that cost is low is adapted at using on domestic most of circulating water system.
