Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0021] The invention discloses a kind of algae to water quality COD Mn Contribution estimation method, by simulating the quantitative response relationship between lake algae biomass and water quality indicators Mn Contributions are estimated.

[0022] Among them, algae on water quality COD Mn The calculation formula for the quantitative fitting of contribution and lake algae density D is:

[0023] A CODMn =-20.912+1.357Ln(D);

[0024] Among them, D is the algae density, the unit is cell / L, and the algae density D is required to be greater than 5.5×10 6 cell / L.

[0025] Among them, the simulated algae growth temperature of this estimation method is 15°C in spring and 23°C in summer.

[0026] The step of simulating ...

Abstract

Provided is a method for estimating contribution of algae to water quality CODMn. Algal CODMn is estimated by simulating the quantitative response relation of lake algal biomass and water quantity indexes. The quantitative fitting calculation formula is ACODMn =-20.912+1.357Ln(D), wherein D is the algae density, the unit is cell / L, and the algae density D is required to be larger than 5.5*106 cell / L. By means of the estimation method, different temperatures and nutrient levels are simulated, a method system of contribution of the algae to water quality CODMn is formed through measurement of algal biomass and the water quality indexes and model fitting, theoretical bases and technological guidance are provided for calculating actual contribution of algal matter to eutrophic lake water quality, the quantitative relation between micro algal matter and macro water quality indexes is built, and technological supports are provided for treatment practice of algal bloom ecological catastrophes. Evaluation results are little in deviation, and real conditions can be reflected accurately.

Description

technical field [0001] The invention relates to the technical field of lake ecological control, more specifically to a kind of algae on water quality COD Mn The estimation method of contribution provides theoretical basis and data support for quantitative research and solution to ecological disasters of algal blooms in lakes. Background technique [0002] In a healthy lake ecosystem, the proportion of nitrogen and phosphorus input from exogenous sources in the utilization of phytoplankton, sedimentation and adsorption, utilization of aquatic plants and microorganisms, and the circulation of substances entering the atmosphere is in a dynamic balance. Due to the special sensitivity and high adaptability of planktonic algae to nutrients, the dominant algae in eutrophic lakes proliferate abnormally, often forming "algae blooms", destroying the balance of material and energy exchange in aquatic ecosystems, and causing ecological catastrophes in severe cases. The control and remo...
