Embodiment Construction

[0035] Since the concentration of chlorophyll a has a good correlation with the density of cyanobacteria, the following is the use of a chlorophyll a meter to monitor the changes in the concentration of chlorophyll a in the water body before and after the application of condensed algae materials compounded with different component ratios. The results are as follows:

[0036] Prepare 5 parts of blue-green algae water body with standard concentration, and the concentration of chlorophyll a is 1×10 2 mg / L, 5×10 2 mg / L, 1×10 3 mg / L, 5×10 3 mg / L, 1×10 4 mg / L. Compound algae condensing materials A, B, C, D, E according to a certain ratio, add 1-5 mg / L algae condensing material to the algae-containing water body, mix for 1-5 minutes and let stand for 10-30 minutes, filter out the water surface and float After the algae condensate, the chlorophyll a concentration of the water body is measured again, and the chlorophyll removal rates of five different components and ratios of algae...

Abstract

The invention relates to an algae setting material, which comprises 5 to 70 percent of natural fiber material and 30 to 95 percent of natural high polymer material, wherein, the natural fiber material is selected from plant fiber and / or animal fiber, and the natural high polymer material is selected from crab derivatives and / or shrimp derivatives and plant viscous juice with a proportion no less than 5 percent. The algae setting material is the natural substance without any harm to human bodies, livestock, environment as well as aquatic animals and plants, and has coagulation, adsorption, tangling and enmeshing function for the algae. When the use amount of the algae material is 0.1 to 10mg / L, the removal efficiency of the algae is over 95 percent. The obtained algae setting body of the flocculation has strong holding power, good performance of floating and drainability, little algae mug and convenient post-process, so the invention is applicable to urgent treatment of burst red tide in ease water and water bloom in fresh water.

Description

1. Technical field [0001] The invention relates to a flocculation material, in particular to a flocculation material for treating harmful algae polluting water sources, in particular to an ecological flocculation material. 2. Background technology [0002] The outbreak of harmful algae in natural seawater, lakes and rivers (commonly known as red tide in seawater and algae bloom in freshwater) has become a global environmental pollution problem. Among the four major freshwater lakes in my country, Chaohu Lake and Taihu Lake are frequently polluted by algae, especially in the early summer of 2007, the sudden cyanobacteria bloom in Taihu Lake formed a huge airtight pollution group in some areas, which seriously affected the safety of humans and animals in the surrounding areas of Taihu Lake. , Shocked at home and abroad. The outbreak of harmful algae not only seriously deteriorates the water quality, depletes oxygen, and kills a large number of fish, but also algae toxins can e...
