Description
Technical field
The present invention relates to a kind of water purifying device and comprise the water delivery engineering system of this water purifying device.
Background technology
The cooling water of people's daily life, industrial water, factory or desalinization water all will obtain fresh water or seawater from natural water source by water delivery engineering.But no matter the natural water in the natural water source is seawater or fresh water, wherein all contains the larva of many impurity and fouling organism.Impurity such as the silt in the natural water can cause wearing and tearing to water delivery engineering and equipment after entering water delivery engineering with the water body of carrying, reduce the service life of water delivery engineering, equipment, impurity such as these silts precipitate alluvial in pipeline, in the course of time cause the obstruction of pipeline, directly have influence on the conveyance power of water of water delivery engineering; The fouling organism larva of carrying water body to carry enters just to select a good opportunity behind the water delivery engineering and is attached to the engineering body surface and grows and be adult (fouling organism), these fouling organisms shoot up in water delivery engineering and constantly breeding, water delivery engineering is caused in various degree biodeterioration, bring harm and the destruction more serious than impurity such as silts to water delivery engineering, even cause interruption of service.
Described fouling organism refers to be attached to the engineering body surface in the water delivery engineering and the zoobenthos adult of causing biodeterioration.Described fouling organism is attached to body surface, and generally just no longer movement or moving range are little later on, can not enter water delivery engineering with the current of carrying, can not shift out water delivery engineering with current, so generally can directly not intrude in the water delivery engineering as the zoobenthos adult of fouling organism itself yet.The species of described fouling organism have a lot, such as natural pond clam (the Limnoperna fortunei that Mytilidae is arranged, be commonly called as the fresh water mussel, the domestic unique fresh water species of China), zebra mussel (Dreissena polymorpha, English zebra mussels, the invasive species that America is famous is lived in the seawater), Mytilus galloprovincialis (Mytilus edulis), Perna viridis multiple mussels such as (Perna viridis) also has arthropod barnacle (Arthropoda, Crustachia, the cirrus order, Balanidae), oyster (Mollusca, lamellibranchiata, Anamorpha, the pearl shell order), and sponge, the crinosity annelid, Ascidian etc.
Described fouling organism larva refers to that fouling organism still is in the biology in the stage of swimming in childhood, and it has initiatively attachment bulk properties and passive migrate attribute usually.Described fouling organism larva lives in the water body, can not cause direct harm to water delivery engineering, but it has with the characteristic of current migration and the characteristic of initiatively adhering to object, when it enters water delivery engineering and be attached to the engineering body surface with current, just can grow up to grow is fouling organism (zoobenthos adult), so the fouling organism larva is the fouling organism source of invasion water delivery engineering.Described active attachment bulk properties is the biological nature that described fouling organism larvae development is adult (zoobenthos), if its have no chance to adhere to object all the time will natural death, so it initiatively adheres to the very competent of object.Described fouling organism larva has passive migrate attribute, and initiatively locomotivity is very poor for it, can only just can be attached to body surface by the chance that current provide.
Described engineering object refers to the operational outfit of water delivery engineerings such as the structure object of pipeline, box culvert, tunnel and appurtenant work thereof of water delivery engineering and water pump, gate valve, and the material of engineering object is mainly cement, metal, timber, plastics.Described water delivery engineering comprises life, water for industrial use water delivery engineering, the water delivery engineering of factory's cooling water, desalinization water delivery engineering etc.
Described biodeterioration refers to described fouling organism at the raised growth of engineering body surface, cause equipment can not normally move, effectively the reduction of water delivery caliber and to after the burn into death of engineering surface to the pollution of water body.
The larva of fouling organism is very strong to the invasive ability of water delivery engineering, and at the peak season of breeding, the density of natural pond clam larva can reach 5000/m in the natural fresh water water body
3More than.Natural pond clam larva in the fresh water can enter for delivery of the aqueduct of domestic water and water for industrial use or the cooling water pipeline of factory with current; And the mussel in the seawater or kentrogon can enter desalinization pipeline or cooled with seawater waterpipe (as the cooling water pipeline in power station) etc. with seawater.Fouling organism to water delivery engineering cause stained quite serious, for example fresh water fouling organism natural pond clam is attached on the structure wall such as tube wall, gate valve, box culvert, tunnel of pipeline even seam crossing, and the growth thickness in 1 year can reach several centimetres, and density is up to 10,000-100,000/m
2, not only make the reduction of effective water delivery caliber, and its byssus gos deep into the structure wall, can corrode wall; Gate valve then can't normally be opened or be closed after being wrapped up by the natural pond clam; After the clam natural death of natural pond, smelly polluted water can go bad; The shell that splits away off deposits in a large number in pipeline turning point or crotch, causes that the pipeline current are not smooth, reduces the conveyance power of water of pipeline.The desalinization pipeline of conveying seawater or cooled with seawater waterpipe etc., also can run into same problem, such as the barnacle that is attached to the engineering body surface each time the decortication after, will secrete a kind of first rubber of barnacle of viscosity, this glue contains multiple biochemical composition and extremely strong bonding force, make barnacle have extremely strong adhesive ability, adhering to for the factory that is used for cooling for seawater desalting plant or extracting seawater of they is puzzlement greatly and burden, and annual extremely huge manpower and the fund of all must expending in the whole world removed on the fouling organism.Therefore, the fouling organism of eliminating in the water delivery engineering (no matter fresh water or seawater) just becomes a realistic problem that needs to be resolved hurrily.
The existing fouling organism of killing mainly contains with the method that reduces the fouling organism adhesion amount:
1, artificial shovel is scraped method: namely all will shovel ducted fouling organism and scrape processing every year.Work for the treatment of must be carried out under situation about cutting off the water completely, not only needs to drop into great amount of manpower and material resources, scrapes in the process also and can cause to a certain degree damage to the water delivery tube wall at shovel, has influence on the service life of water delivery engineering.And the tube wall of shovel after scraping is more coarse before shovel is scraped, and is more conducive to adhering to of tool fouling organism, can bring bigger hidden danger.
2, coating protecting method: namely use protective coating, to improve the smoothness of body surface, reduce the adhesion amount of fouling organism, contain pesticide in some coating, can kill fouling organism.From applicable cases, regulation effect is not obvious.
3, chemistry is killed method: studied the control test that the number of chemical killing agent is used for biodeterioration at present, as adopting chlorine and clorox as the agent for killing of natural pond clam, but the report of practical application is few.In the drinking water water delivery engineering, though can preventing and treating the fouling organism invasion, chemical method reduces biodeterioration, and it is very careful to need, and chemical agent is not all allowed to ignore to the influence of water quality and environment, and huge chemical agent amount cost is very high.
These methods all can be used to administer the fouling organism adult, but effect is all not good.Though described fouling organism larva individuality is very little, still can natural subsidence under the condition of sluggish flow.The present invention looks for another way, and starts with from the larva of fouling organism, reaches the purpose of removing the fouling organism larva by sedimentation.
