Abstract
The invention discloses a marine creature control process of a seawater direct current cooling system, and relates to the field of marine creature control, in particular to the marine creature control of the seawater direct current cooling system. The marine creature control process of the seawater direct current cooling system comprises the following steps: adding a molluscacide composition consisting of polyquaternium and bleaching water, dosing the bleaching water daily, and dosing the polyquaternium by stages; and diluting the molluscacide with water till 8-10 times through a pipeline mixer when dosing the molluscacide, and dosing the molluscacide into the water. The marine creature control process can safety control the marine creature growth in the seawater direct current cooling system, safely and reasonably utilize seawater and ensure the safe operation of the seawater direct current cooling system.
Description
Technical field
The present invention relates to marine organism control field, particularly the marine organism control of seawater direct-current cooling system.
Background technology
The development in more current coastal cities is seriously limited by Freshwater resources and lacks situation, utilizes on a large scale seawater will produce far-reaching influence for coastland future development, and utilize on a large scale the key of seawater, is the marine life growth of how controlling in seawater.The technology of controlling at present marine life growth has electrolytic seawater to kill shell, chlorine kills shell, non-oxidizable medicament kills the technology such as shell, but existing several processing mode respectively has drawback: electrolytic seawater technology is subject to the requirement of region and environmental protection cannot meet operating requirement, electrolytic seawater requires restricted to seawater, satisfactory qualified product cannot be made in waters, some areas, the clorox of making because of the restriction of local water area water-quality such as the electrolytic seawater system of Qinhuangdao factory contains quantity not sufficient, uncontrollable shell growth, condenser is stopped up and causes unit disorderly closedown by shell, chlorine toxicity does not meet environmental requirement and substantially exits application, and for example Zhuhai factory was used chlorine to control shell before 01 year, used non-oxidizable medicament after 01 year instead, non-oxidizable medicament is in the market controlled producer because medicine component exists drawback-irritant, life-time service shell can develop immunity to drugs, make shell control the difficulty that becomes gradually, use-pattern is that oxidisability medicament and non-oxidizable medicament are hitting property of flood and add in addition, there is drawback in use-pattern, this type of medicament is used and causes Shanwei factory in August, 09 shell to stop up condenser.
Summary of the invention
The object of the present invention is to provide a kind of marine organism control technique of seawater direct-current cooling system of effective control marine life growth.
Object of the present invention can realize like this, designs a kind of marine organism control technique of seawater direct-current cooling system, comprises the following steps:
A, input form molluscicide by polyquaternium, Javelle water and combine, and Javelle water adds every day, and polyquaternium adds stage by stage; Described polyquaternium is poly-Dichloroethyl ether Tetramethyl Ethylene Diamine;
B, molluscicide combination are doubly added in water by line mixer dilute with water 8-10 while adding;
C, add dispersion agent, dissolve and remove marine life secretory product, the corpse in water system and stick to the marine life in anabiotic state in system; Described dispersion agent is DMAD;
Wherein, polyquaternium concentration is 1.5 to 2ppm, and input is 1 time/every 7 to 15 days, and each treatment time is 2.5 to 5.5 hours; Javelle water concentration is 6 to 12ppm, and input is 2 times/every day, and each treatment time is 1 to 2 hour; Dispersant concentration is 0.3 to 0.7ppm, and input is 1 time/every 15 days, and each treatment time is 1.5 to 2.5 hours;
In typhoon the day before yesterday, add input: polyquaternium concentration is 2ppm, adds continuously 6 hours; Javelle water concentration is 15ppm, 3 hours/time treatment times, 2 times; Dispersant concentration is 0.5ppm, adds continuously 3 hours.
The present invention can safety control seawater direct-current cooling system in the growth of marine life, safety is rationally utilized seawater, guarantees the safe operation of seawater direct-current cooling system.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
A marine organism control technique for seawater direct-current cooling system, comprises the following steps:
A, the molluscicide dropping into by polyquaternium gathers, Javelle water forms combine, and Javelle water repeatedly adds every day, and polyquaternium adds stage by stage.
B, molluscicide combination add by line mixer dilute with water 8-10 doubly, are added in water more uniformly.
C, add dispersion agent, dissolve and remove marine life secretory product, the corpse in water system and stick to the marine life in anabiotic state in system.
Salt water cooling system is killed to shellfish to be processed, difference according to marine life at intrasystem upgrowth situation, breeding cycle, the time point of swarming, weather etc., formulate chemical feeding quantity, the dosing frequency of different steps, drop into the non-oxidizable and oxidisability molluscicide being formed by polyquaternium, Javelle water and dispersion agent and combine.
Described polyquaternium, concentration is 1.5 to 2ppm, and input is 1 time/every 7 to 15 days, and each treatment time is 2.5 to 6 hours.
Described Javelle water concentration is 6 to 12ppm, and input is 2 times/every day, and each treatment time is 1 to 2 hour.
Described dispersion agent is DMAD, and concentration is 0.3 to 0.7ppm, and input is 1 time/every 15 days, and each treatment time is 1.5 to 2.5 hours.When adding, described dispersion agent is doubly added in water by line mixer dilute with water 8-10.
In typhoon the day before yesterday, add input:
Poly-Dichloroethyl ether Tetramethyl Ethylene Diamine concentration is 2ppm, adds continuously 6 hours; Javelle water concentration is 15ppm, 3 hours/time treatment times, 2 times; Dispersant concentration is 0.5ppm, adds continuously 3 hours.
Yi Mou power plant is example, and scheme is as follows:
The non-summit of growth phase of time period 1 (12～March)
The non-summit of growth phase of time period 2 (November, April)
The 3 summit of growth phases (May-October) of time period
Initiate emergency plan before typhoon:
A, startup rotary sieve, the rubbish of sending someone to clear up at any time at the scene, keeps current unimpeded, prevents that rubbish from stopping up filter screen.
B, at typhoon, within first 1 day, to keep adding:
Polyquaternium 2ppm adds 6 hours continuously;
Javelle water chemical feeding quantity 15ppm 3 hours/time, 2 times/day;
Dispersion agent 0.5ppm adds 3 hours 1 times/day continuously.
Regularly add Javelle water 2 times every day, for controlling ovum and the larva of marine life in sea water system, makes marine life be controlled in cradle state, and the marine life in this period is that most fragile holds manageable period most, the poly-Dichloroethyl ether Tetramethyl Ethylene Diamine (CM-WT-01) of non-oxidizable molluscicide is mainly to kill adult marine life, because in controlling the process of ovum and larva, always the section of the having time is to stop treated state, likely make this period some ovum and larva be grown up, grow into the adult stage, adding non-oxidizable molluscicide this period wants evenly, time enough, in last 2 hours, add dispersion agent simultaneously, thereby kill with scavenge system in ovum, larva, adult, those are not killed but the marine life in anabiotic state to add dispersion agent and be major control, this class marine life is not easy to stick in system when adding dispersion agent, thereby go out outside system with current.
The present invention both had stronger killing and inhibition ability to multiple marine life, can also take away the marine life corpse and the secretory product that in water system, exist, made water system keep long-term clean state, thus the safe operation of the system of assurance.
