By (丁秀玉news correspondent蒋丽丹) large-scale outbreak of algae in Taihu Lake, a wake-up call to people, but also specializes in sewage treatment equipment to provide a development opportunity. Changzhou new material from the vast R & D Technology Co., Ltd. own the "direct oxidation of high-energy physics algae processing system," recently put into use by the environmental monitoring department tested the water and out of the system to deal with the pollutant concentration is favorable and effective to deal with cyanobacteria .
The system of water collection devices, including algae, algae-laden water separation, high-energy physics and phosphate oxidation reaction zone collection device. The basic principle is: the collection of algae-laden water through the separation device into the room laden water pressure after the separation, re-entering the oxidation zone of high-energy physics strong and strong oxidation oxidation-reduction reaction. Oxidation by strong oxidants algae and algae by the direct oxidation and reduction of nitrogen into water and nitrogen. Algae in the role of phosphorus in the hydroxyl and water under the calcium and magnesium to form calcium phosphate salt and magnesium salt and so on. Phosphate recovery through the collection device to achieve the water to remove algae and algae-laden water purification purposes.

Its main features are: the collection of the algae-laden water, algae-laden water separation, oxidation and decomposition strong adsorption and ion exchange to focus on the same system, the true realization of the functions of the NPC and does not cast any chemical agents, and no secondary pollution of the environment .

Changzhou City Environmental Monitoring Central Station track and monitor the system indicates that cyanobacteria contaminated water treated by the system, the total number of algae treatment rate was 98.9%, total nitrogen treatment rate to 69.5%, total phosphorus processing rate of 92.2%, P acid treatment rate was 92.0%, chlorophyll a processing rate of 93.0 percent, a significant treatment effect. System in the total number of species (ie species density) of more than 200 million / L when the speed control at 0.3 m / s below 050 million less than the total number of algae / or control when the speed of 3 m / sec. Lake algae by the total number of 100 million / L calculations, the system up to date to deal with 136 tons of algae (at 6 hours, the wet weight), to deal with the surface area of about 0.4 square kilometers.
