High efficiency algae flooculation agent, method for treating red tide and plakton bloom using same

Abstract

The present invention provides a method for preparing high-effective algae flocculant from non-toxic, easy-to-bio-degrade, cheap, natural macromolecular polymer modified clay. Said modification can obviously raise flocculation algae-removing capability of different clay, the algae-removing rate of various clays can be 20-95% Said high-effective algae flocculant can be used for controlling and treating large area red tide, fresh water algal bloom, and also can be used for removing harmful algae in river and drinking water plant.

Description

technical field

[0001] The invention relates to the preparation of an algae flocculant and a method for controlling seawater red tide and freshwater bloom. Specifically, it uses natural, non-toxic, and biodegradable high-molecular polymer modified clay that will not cause secondary pollution to the environment to produce a type of high-efficiency algae flocculant, and use it to treat seawater red tide, freshwater Algal blooms, harmful algae pollution methods for river courses and drinking water plants. Background technique

[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. It not only seriously deteriorates water quality, depletes oxygen, and causes a large number of fish to die, but also algae toxins can enter the food chain and cause human diseases and even death. So far, there is no technology in the world that can safely,...
