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 through 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 getting into 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; Just selecting a good opportunity behind the fouling organism larva entering water delivery engineering of carrying water body to carry and being attached to the growth of engineering body surface is adult (fouling organism); These fouling organisms shoot up in water delivery engineering and constantly breeding; Water delivery engineering is caused biodeterioration in various degree; Bring harm and the destruction more serious to water delivery engineering, even cause interruption of service than impurity such as silts.
Said fouling organism is meant engineering body surface that is attached in the water delivery engineering and the zoobenthos adult of causing biodeterioration.Said fouling organism be attached to body surface later on general just no longer move or moving range little; Can not get into water delivery engineering with the current of carrying; Can not shift out water delivery engineering, so generally can directly not intrude in the water delivery engineering as the zoobenthos adult of fouling organism itself with current yet.The species of said 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.
Said fouling organism larva is meant 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.Said fouling organism larva lives in the water body; Can not cause direct harm to water delivery engineering; But it has characteristic and the characteristic of initiatively adhering to object with the current migration; When it gets into water delivery engineering with current and attached to the engineering body surface; 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.Said active attachment bulk properties is the biological nature that said 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.Said 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.
Said engineering object is meant the operational outfit of water delivery engineerings such as structure object and water pump, the gate valve of pipeline, box culvert, tunnel and the appurtenant work thereof of water delivery engineering, and the material of engineering object is mainly cement, metal, timber, plastics.Said 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.
Said biodeterioration is meant the raised growth of said fouling organism at the 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 get into current and be used to carry the aqueduct of domestic water and water for industrial use or the cooling water pipeline of factory; And mussel in the seawater or kentrogon can get into desalinization pipeline or cooled with seawater waterpipe (like 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 walls such as the tube wall of pipeline, gate valve, box culvert, tunnel 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 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 pipeline turning point or crotch in a large number, 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 attached to the barnacle of engineering body surface after decortication each time; 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 seawater desalting plant or extracting seawater are used to cool off 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: promptly all will shovel ducted fouling organism and scrape processing every year.Carry out under the situation that work of treatment must be cut off the water completely, not only need drop into great amount of manpower and material resources, scrape in the process at shovel and also can cause damage to a certain degree, have influence on the service life of water delivery engineering the water delivery tube wall.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: promptly use protective coating,, reduce the adhesion amount of fouling organism, contain pesticide in some coating, can kill to fouling organism to improve the smoothness of body surface.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 the clorox agent for killing as the 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 said 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 through sedimentation.
