Description
Technical field
The present invention relates to a kind of real time monitoring apparatus, relate in particular to a kind of monitoring and the all-around ultrasonic wave algal removal floater of administering in one that is applied to water environment protection, belong to the wireless monitor field.
Background technology
Along with the expansion of the development of global economy and the effect of human activity, lake eutrophication is on the rise.The water body of eutrophication very easily causes breaking out of blue-green alga bloom, this one of water environmental problems that become international.The breaking out of blue-green alga bloom has periodically, by real-time monitoring and warning and be aided with effective control measure, can prevent that blue-green algae from breeding in a large number, alleviates the harm that it brings.
Studies show that the main environmental conditions that influences blue algae growth is illumination, water temperature, pH value, dissolved oxygen DO, nutrient concentration, wave disturbance etc.In case environment forms, at nutrients and unrestricted initial stage of space scale, algae can enter an exponential growth phase, wawter bloom will be broken out in " overnight " comprehensively, cause unmanageable situation, to such an extent as to the later stage need spend lot of manpower and material resources and salvage cleaning, therefore the real-time for blue algae monitoring early warning and control seems particularly important.
The main at present monitoring mode that adopts has three kinds: artificial field observation, satellite remote sensing monitoring and the monitoring of water quality automatic on-line.Regular artificial on-the-spot vision and sense of taste observation are effectively a kind of and monitoring method intuitively, but monitoring periods is long, and technician's experience is required height; The satellite remote sensing monitoring technology has macroscopic view, dynamic dispatching distinguishing feature, but the procurement cost height of remote sensing images, it is with high content of technology that Treatment Analysis requires, and is applied to large-size lake and reservoir usually; Water quality and meteorologic parameter automatic tester are applied at automatic water quality monitoring station and automatic weather station respectively at present, yet the restriction of the condition of being built a station, usually the two distributing position and density are all inconsistent, cause sampled data can not accurately reflect environmental factor with a slice waters, the impact prediction precision, and because all departments' division of duty difference, obtaining of each parameter proposed high requirement to the cooperation between environmental protection, water conservancy and the meteorological department.
The water environment situation difference in each lake, estimating under blue-green alga bloom genesis mechanism and unclear situation is the comparison difficulty, the predictablity rate that this limitation causes lowly causes breaking out the hysteresis of initial stage early warning issue and the delay of control measure probably, has incured loss through delay Optimal Control period.
Blue-green algae control is the most effective, scientific methods is to adopt ecological management, recovers the self-purification capacity of water body.Complete ecological chain can strengthen the repair ability of water body self: the organic contamination of aquatic animals such as aquatic hygrophyte and fish, shellfish in can not only consume water, can also suppress algal grown.Yet this is a kind of long-term comprehensive improvement, need be based upon external source and pollute controlled and possess on the basis of self-purification capacity, for contaminated water body, its environment has hindered the normal growth of aquatic animals and plants, cause the imperfect of biologic chain, therefore must adopt removal measure.
Sweep-out method for blue-green algae has had a lot of researchs both at home and abroad, mainly contains chemical method, bioanalysis, physics method etc.Wherein chemical method can efficiently remove algae, but the chemical agent that is to use very easily causes secondary pollution to water body, and developed country does not re-use basically now; Bioanalysis easily causes the high hydrophyte excessive multiplication of introduction, and lake biotic population structure, shipping, view etc. are brought adverse effect; Traditional physical method has mechanical removal, filtration, aeration, shading, excavation bed mud etc., needs large-scale plant equipment and experienced operating personnel, wastes time and energy for water body in large.
Ultrasonic algae removal device has obtained successful Application abroad, and correlative study has also been done by domestic part colleges and universities, but does not enter the commercialization stage as yet.Government and environmental administration mainly are devoted to the protection and the improvement of large-size lake and important water head site; and existing ultrasonic algae removal device depends on the supply of electric power; wiring is difficult for, and is subjected to self to move the restriction with effective range, and the blue-green algae that mainly is limited to the small size water body is at present administered.
Existing ultrasonic algae removing device can be divided into fixed and mobile model.The former is many with ultrasonic-frequency power supply and transducer separation, the two signal wire by waterproof connects, and power supply is installed in the land, transducer by mark post or lanyard under water, only can be to the directed irradiation in the fan-shaped waters in the place ahead, the size of the field angle of transducer and acoustical power decision effective irradiation face.In order to enlarge moving range, also there is the people that the ultrasonic algae removal device of the whole series is installed on the spitkit, by the generator powered of cable or boat-carrying, this method depends on long manually-operated, and equipment volume is big, cost is high.
