Description
Technical field
The utility model relates to water technology, particularly relates to a kind of technology of marine plankton inactivating device.
Background technology
Along with the fast development of modern chemical industry, agriculture production, increasing of coastland population, a large amount of industrial and agricultural wastewater and sanitary sewage enter ocean, wherein quite a few unprocessedly just directly enters ocean, cause coastal waters, bay Eutrophic Extent is on the rise, planktonic organism amount reproduction, thus cause red tide phenomenon; In addition, along with the high speed development of International Maritime Industry, the discharge of boats and ships seawater causes the introducing of external harmful plankton species, exacerbates the deterioration of marine ecology chain and environment.International Maritime Organizaton's research finds to have the organisms such as 7000 planktonic organisms every day at least with boats and ships oceangoing voyage to other country strange land.It can thus be appreciated that various countries' species are all carrying out mutual invasion in various degree every day.New species invade new harbour environment, once there is no natural enemy, will amount reproduction, and then cause regional ocean water quality deterioration.The planktonic organism invasion that boats and ships bring has obtained the extensive concern of various countries, and be it is believed that it is that four of harm ocean one of is endangered greatly.
In order to more effectively kill harmful water planktonic organism and pathogenic agent in the closed marine site such as harbour, coastal waters, prevent regional seawater quality from worsening, the marine plankton inactivating device that sea environment-friendly industry urgent need is a kind of fast, efficient, reliable, treatment capacity is especially big.Planktonic organism for water body in large is administered and the technology that prevents external unwanted aquatic organism, pathogenic agent from invade and equipping accordingly and facility, must following characteristics be possessed: 1) deactivation speed is fast: otherwise, in water body in large, when the water after process enters in body water again, what such as add is biocide, will be weakened sterilizing ability very soon by diluting, and adds the microorganism do not killed in a large number, understand large-scale breeding very soon, regulation effect is very poor; 2) kill efficiency is high: must meet sea environment-friendly seawater discharge standard in the industry; 3) secondary harm can not be produced to ecotope; 4) processing power is large: water body in large is as the eutrophication problem at harbour, and the processing power of single device is one of key factor, general requirement unit processing power hundreds of ton/hour ~ a few kiloton/hour.
The Treatment process system of existing body eutrophication and red tide, and planktonic organism inactivation treatment technical system, mainly contain electrolysis and produce active substance sterilising technology, ultraviolet sterilization technology.
