Abstract

The invention relates to a collection and treatment method of near-shore cyanobacteria bloom. The specific implementation steps include: a. a water pump continuously pumps water from the near-shore area to be cleaned where cyanobacteria are concentrated to a water seepage tank for filtering and seepage, cyanobacteria are collected in the water body into the water seepage tank to form accumulated cyanobacteria, and clean water filtered by the water seepage plate is discharged into the clean water area through a drainage pipe; b, the collected cyanobacteria are added into a screw extruder for extrusion and dehydration, and the MC-containing wastewater and the squeezed cyanobacteria are subjected separately collecting and treating; c, the collected wastewater is subjected to secondary treatment in an ultraviolet treatment box and an ozone treatment box in turn; d, the collected dehydrated cyanobacteria are put into a heating copper sleeve for heating and inactivation, so that they can bekept for a long time at 40-50 DEG C, the biological activity is basically lost. The invention can collect and salvage the coastal cyanobacteria, reduce the MC content in the water body, prevent the cyanobacteria from obtaining biological competitive advantages, and thereby prevent the occurrence and deterioration of cyanobacteria bloom.

Description

technical field

[0001] The invention relates to a method for collecting and treating nearshore cyanobacteria blooms, and belongs to the technical field of prevention and treatment of cyanobacteria blooms in the biological environmental protection industry. Background technique

[0002] In recent years, with the rapid development of the economy, the problem of water pollution has become increasingly serious. Since the drinking water crisis caused by cyanobacteria blooms in Taihu Lake in 2007, cyanobacteria blooms have always attracted the attention of all walks of life. If the cyanobacteria are not cleaned up in time, the toxins produced will pose a fatal threat to aquatic organisms, and the death and decomposition of cyanobacteria will consume a large amount of oxygen. The lack of oxygen in the water body will destroy the normal food chain, threaten the safety of drinking water, and cause serious economic losses and social problems.
