Description

Application and the using method thereof of biological cleanser in circulating water system

The present invention relates to a kind of scavenging agent in new Application for Field and using method thereof, particularly application in the industrial cycle water system and using method thereof.The invention still further relates to new removal and the control method of greasy dirt leaked substance in a kind of circulating water system, biological clay, bacterium algae.The invention still further relates to a kind of with biotechnological formulation composite possess inhibition, scale inhibition, decontamination, antibacterial multi-functional compound novel water quality stabilizer.

Owing to the exhaustion day by day of water resources on the earth, mention on the agenda at present for the requirement of water saving.Therefore, the use technology of recirculated water has been widely used in such as every field such as oil, chemical industry, metallurgy, power station, food.

But in the application of recycling technology, As time goes on, occurred new problem again: the heating surface of production equipment is through perforation occurring behind the erosion corrosion constantly, leak, cause production material to enter circulating water system, and along with the circulation of system, leakage constantly increases, be full of the full cycle water system, cause and be full of leakage in the circulating water system, the biological clay alluvial, the bacterium algae is out of control, thereby causes the scale inhibition of conventional water quality stabilizer, inhibition, the reduction of the function of sterilization algae removal very causes in complete failure, pipe network finally occurs and stops up, corrosion increases the weight of, the full cycle water system can't normally be carried out, can make system be forced to stop when serious.For addressing these problems, at present at home and abroad, the way that has nothing better basically generally all adopts disinfecting scrub decontamination method.The shortcoming of this method is to impact to give birth to greatly, repeatedly use a large amount of clean-out systems, tensio-active agent, sterilant, and the full cycle water system is thoroughly cleaned.Therefore, its dosage is also big, and drug concentration generally will reach tens and even hundreds of PPM.And all need carry out the big yield displacement after the washing at every turn, thus reduced the cycles of concentration of recirculated water, improved fresh water and conventional water quality stabilizer consumption, the running cost of circulating water system improves greatly.Even but like this, effect is still not thorough, still have residue to exist, when particularly leaked substance is organic class, lipid, nutrition agent, more difficult proving effective.The self-circulating water technology is used so far, leakage causes that the state of circulating water system vicious cycle is perplexing the experts and scholars of circulating water treatment both at home and abroad always, and they appeal constantly that on a large amount of technical magazines, academic report and technical seminar people solve this difficult problem.Even in China Petrochemical Industry's specialized management meeting, also ask a question, require people to strengthen management, strengthen monitoring, strengthen sterilization, not there is good plan.

Purpose of the present invention is exactly in order to address the above problem, application and the using method thereof of a kind of biological cleanser in circulating water system proposed, it can solve in the recirculated water that causes that dirt increases under the material from leakage situation, biological clay alluvial, bacterium algae phenomenon out of control, and provide a kind of biotechnological formulation composite possess the antibacterial multi-functional water quality stabilizer of corrosion-mitigation scale-inhibition decontamination.

Technical solution of the present invention: application and the using method thereof of a kind of biological cleanser in circulating water system, it is characterized in that it adopts biological enzyme scavenging agent to add in the recirculated water of circulating water system, and add with trace at every turn, make that the commodity concentration that at every turn adds the biological enzyme scavenging agent in the recirculated water of back is 1.00-0.01PPm, thereby the removal of the greasy dirt in recirculated water leakage, material are degraded.

The present invention adopts biological enzyme scavenging agent first in the Handling of Stabilizing Water Quality of circulating water system, it can fully be degraded the leaked substance of the organic class in the recirculated water, lipid, nutrition class, bacterium algae in the recirculated water is controlled, and biological clay is disappeared, thereby the function of conventional water stabilizer is given full play to, reduce corrosion and, make circulating water system enter optimum running status, guarantee the long-time heavy-duty service of production equipment by the material from leakage that corrosion causes.The present invention is because trace uses biological enzyme scavenging agent, then this medicament can play Degradation in recirculated water, simultaneously can guarantee that again the bacterium algae can be not out of control because of the activation of enzyme in the recirculated water, thereby make the expensive application of biological agent in large-scale industry become possibility, it is compared with existing disinfecting scrub decontamination method commonly used, systematic running cost can reduce greatly, reach 20～50%, and system operates steadily, management difficulty reduces, and easy to use, workload alleviates greatly, in the prolonging overhaul cycle, system can hang down the turbidity operation for a long time.Can be all the year round by zero release design requirements operation for no leakage system as long as enlarge other filter scale.In addition, the present invention can also make things convenient for leakage detection, impels leak source to repair as early as possible, the function that keeps other filter tank has improved the clear water ratio in other filter tank and the cycles of concentration of circulating water system, reduces the chlorine consumption, significantly reduce the consumption of fresh water, and then reach water-saving purpose.

Embodiment:

With internal circulating load is 13000 tons, possess 6500 tons of the water yields, cycles of concentration 2-3 circulating water system doubly is an example, add biological enzyme water purification agent to the circulating water system trace every day, this scavenging agent preferably adopts active clean-out system (SGO) [water purification king (Shur GO) recombiner], its outward appearance is the brown translucent liquid, and the pine tar flavor is arranged, and foam is arranged after the concussion.4 kilograms of add-on every days, drug concentration is 0.6ppm in the recirculated water like this.The water quality stabilizer that add every day in this system is 95 kilograms, 16 kilograms in chlorine, and be two months period of a permutation.Among the present invention, at every turn adding of biological enzyme scavenging agent adds after can be with conventional water stabilizer composite, also can add respectively.After composite, add, can following method carry out with water quality stabilizer.The component of above-mentioned water quality stabilizer can be, and 15 kilograms of hydroxyl ethylene diphosphonates (HEDP) add 10 kilograms in water, 50 kilograms of multipolymers (ZW-308), 15 kilograms of polymaleic aciies (HPMA), 1 kilogram of benzotriazole (BTA), zinc chloride (Zncl ₂) 4 kilograms.Earlier 15 kilograms of HEDP are diluted with 10 kg of water, add 4 kilograms of water purification agents then, add 50 kilograms of ZW-308 more successively, 15 kilograms of HPMA, 1 kilogram of BTA and 4 kilograms of Zncl ₂, will clarify behind their abundant mixings, can obtain a kind of compound novel water quality stabilizer that possesses inhibition, scale inhibition, decontamination, antibacterial multiple function thus, its every performance all is not less than conventional water quality stabilizer.Get supernatant liquor and drop in the recirculated water, can reach the effect of degraded dirt, scale inhibition, inhibition, inhibition bacterium algae, control biological clay.Its effect is remarkable, dosage is low, displacement in two months springs is (conventional twice of a displacement in month that need) once, monitoring parameter is all up to standard, lacing film outward appearance local corrosion, corrosion rate 0.084mm/y, dirt deposition speed 10.29mcm, slime content 0.6ml, equipment open the lifeless matter foundry loam, and no leakage is adhered to.

Why the present invention can obtain so satisfied effect, is inseparable with the trace input of biological enzyme scavenging agent.In the using method of people's routine, all unexpectedly reduce leakage in the circulating water system, even expect also dare not going application with biological enzyme scavenging agent.This is because the purification mechanism of biological enzyme scavenging agent produces cleaning action to activate organism, it with recirculated water in the behavior of the sterilant sterilization algae removal that adopts of tradition and the requirement that limits bacterium algae sum be inconsistent at all.And its conventional amount used requires greatlyyer, and activity is greater than 1PPm just can reach satisfied effect, and the biological enzyme scavenging agent costs an arm and a leg, and big multiple enterprises can't bear, and has been in the state of not accepted by market as SGO (Shur Go) biological enzyme scavenging agent.The present invention breaks through the people's conventional thinking, courageously with biological enzyme scavenging agent first Application in recirculated water, and micro-appropriateness adds, make it both bring into play the degraded cleaning action of biological enzyme scavenging agent, overcome biological enzyme activation organism in this scavenging agent again, increase the drawback of bacterium algae sum in the water body, satisfy recirculated water heterotrophic bacteria sum and be no more than 5 * 10 ⁵The national standard of individual/milliliter.Why the recirculated water that the inventive method is handled can make bacterium algae sum be inhibited, and can reduce the sterilant consumption, its reason is that biological enzyme activated living organisms has been degraded and can be consumed the organism of sterilant, and a spot of sterilant can partly be killed by biological enzyme activated living organisms, their alternating actions make the bacterium algae sum in the water body reach a kind of running balance.And owing to the minimizing of nutrition agent, adherance, hidden body in the water body has suppressed the breeding of organism to a great extent again, so if the heterotrophic bacterium standard is relaxed in the recirculated water, stop using sterilant, the bacterium algae total amount of recirculated water can be not out of control yet, according to experimental observation, when moisturizing is the service water of non-sterile, obstructed chlorine (Cl in 10-20 days is arranged in the recirculated water under the condition that leakage exists ₂), still aseptic algae out-of-control phenomenon in the recirculated water, the heterotrophic bacterium combined index is 10 ⁵～10 ⁶Between balance.
