Modified clay seawater mixed liquid spraying system for red tide elimination

Abstract

The invention discloses a modified clay seawater mixed liquid spraying system for red tide elimination. The modified clay seawater mixed liquid spraying system is integrally carried on a ship body through a threaded fixing piece and sequentially comprises a first water pump, a filtering water tank, a second water pump, a mixing bin and a spraying device from front to back. The modified clay seawater mixed liquid spraying system is simple in structure, convenient to maintain and large in spraying range, seawater can be taken at any time during operation, a water tank does not need to be provided, the load of a ship body is reduced, the single-time operation radius of the system is enlarged, and the single-time operation time is prolonged.

Description

technical field [0001] The invention relates to the technical field of marine pollution control, in particular to a modified clay seawater mixed solution spraying system for eliminating red tides. Background technique [0002] At present, with the continuous development and utilization of the sea, a large amount of industrial wastewater and domestic sewage in the sea flow into the sea, forming an increasingly serious problem of red tide pollution. Therefore, the society urgently needs a feasible and efficient method for controlling red tide pollution. There are various methods of red tide control, mainly including chemical methods and physical methods; chemical methods are effective, mainly spraying relevant chemicals on polluted sea areas, using chemical agents to inhibit or even kill algae to control red tide organisms, chemical methods are effective Fast, according to relevant information, a variety of chemical agents for red tide control have been studied in the laborato...

There are various methods of red tide control, mainly including chemical methods and physical methods; chemical methods are effective, mainly spraying relevant chemicals on polluted sea areas, using chemical agents to inhibit or even kill algae to control red tide organisms, chemical methods are effective Fast, according to relevant information, a variety of chemical agents for red tide control have been studied in the laboratory, such as copper sulfate and slow-release copper ion algaecides, organic algaecides such as chlorine dioxide and isothiazolinone, ozone As well as Profloxacin, etc., the chemical agent used on a large scale is copper sulfate. This chemical agent is easily soluble in water and has a significant effect on red tide control. However, chemical methods also have significant shortcomings in red tide control. For example, it is easy to cause excessive use of chemicals in the process of red tide control. , resulting in seawater ecological imbalance, causing adverse effects on fisheries, and when chemical methods are used to control red tides in places with fast migration speed under seawater fluctuations, the persistence of chemicals is poor, which can easily cause secondary pollution of chemicals; physical methods mainly include clay method , especially the successful development of modified clay, which is also internationally recognized as an effective method of controlling red tide pollution. It is a method of removing red tide organisms by using the flocculation of clay particles on red tide organisms

The algae removal rate of the modified clay successfully developed in my country at the present stage can reach 95-99% in a small experimental field, but when it is applied in a vast sea area, due to the lack of efficient equipment support, the modified clay method to control red tide pollution has not been in the domestic market. be promoted and popularized

[0003] Chinese patent CN105000648 provides an integrated clay spraying device for red tide control, which solves the problem of equipment support for red tide pollution control by the modified clay method to a certain extent, but there are certain problems in this device, such as the need for self-provided water tanks, which increases the hull The load affects the operating radius of a single spraying and shortens the single operation time. At the same time, the complex structure of the equipment increases the difficulty of equipment maintenance.
