Embodiment

[0055] Heterocurvium akashiwa is a common red tide organism in my country's coastal aquaculture areas. The cells were found to be elliptical through microscope inspection. Combined with fluorescence, counting, spectrophotometry, and chromatography methods, the individual length was about 8-25 μm, and the width was about 6-6 μm. 15μm, with strong planktonic ability, often spreads in the whole sea area when red tide breaks out. A red tide of Heterocurvium akatide broke out in a coastal bay in Qingdao, and the live fluorescence value of chlorophyll in the water body was monitored by an online living fluorometer on the spot> 30ug / L. Comparing with Table 1, the red tide grading and quantification codes in this area are judged as follows: severe red tide (H), diffuse distribution (D), spherical cell monomer (S), small cell (L), strong planktonic ability (H), Add the letter B in front of each indicator, and the code of the H. red tide is BHDSLH according to the above sequence. In Tab...

Abstract

The invention relates to the field of algae disaster control in the water environment, in particular to an implementation method for eliminating red tide by optimizing the modified clay method. Based on the characteristics of red tides and modified clay flocs obtained through monitoring, the real-time status indicators and standardized value grading system of on-site red tide or red tide elimination effect are constructed; Corresponding grade codes of the red tide or red tide elimination effect characteristic index value in the water body; use the above grade codes to compare with the expert system, and obtain the operation plan for optimizing the use of modified clay method to eliminate red tide; after implementing the elimination operation according to the recommended operation plan, real-time Track and monitor the operation effect, and optimize and adjust the operation plan in time according to the effect of red tide elimination. The use of the method of the invention can realize refinement and programming of operations when the modified clay method is used to control the red tide on site, and contributes to improving the field operation efficiency of using the modified clay method to control the red tide.

Description

technical field [0001] The invention relates to the field of algae disaster control in the water environment, in particular to an implementation method for eliminating red tide by optimizing the modified clay method. Background technique [0002] In recent decades, red tides have frequently appeared in sensitive waters such as coastal waters and estuaries. Some toxic and harmful red tides have seriously affected the water environment quality and ecological safety of the waters and adjacent areas, and even directly endangered the health of residents. In order to protect the safety of the offshore ecological environment and ensure the healthy development of the marine economy, especially in some sensitive waters such as water sources, breeding areas, and landscapes that are threatened or directly affected by red tides, there is an urgent need for practical prevention and control that can reduce or eliminate the hazards of red tides measure. [0003] The modified clay method i...
