Water treatment system and method

Abstract

The invention discloses a water treatment system and method. The system comprises a water quality monitoring device, a water quality evaluating device and a water body purifying device, wherein the water quality monitoring device is installed in a water body to be detected and used for obtaining various physical, biological and chemical indexes of the water body to be detected; the water quality evaluating device is used for comparing the various physical, biological and chemical indexes obtained by the water quality monitoring device with the water quality standard to determine whether the water body needs to be treated or not; the water body purifying device is arranged on the water quality monitoring device to be communicated and used for receiving the water body which is determined by the water quality evaluating device and needs to be treated and purifying the water body through at least one treatment device. According to the film and gas separation technology, by applying the film diffusion principle, poisonous and harmful ammonia nitrogen and carbon dioxide in aquatic products in the water body are removed in a physical mode, chemical and biological removal are avoided, the system is applicable to the fast-pace business traffic, and no other chemical matter in the water body is added.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water treatment system and method. Background technique [0002] Ammonia nitrogen pollutants are ubiquitous in water resources. Because conventional water treatment processes are difficult to remove them, they have become one of the main pollutants in water resources treatment, especially ammonia nitrogen in low temperature periods is even more difficult to treat. Ammonia nitrogen pollutants are highly toxic to aquatic organisms, and their toxicity to aquatic organisms can be divided into chronic and acute. Chronic poisoning manifests as: decreased willingness to eat, cell tissue damage, and reduced oxygen transport between tissues; acute poisoning manifests as: aquatic organisms lose their balance or die directly. [0003] Due to the high energy of chemical bonds between the dissolved ammonia nitrogen molecules and water molecules in water, compared with other dissolv...

AI Technical Summary

Problems solved by technology

[0003] Due to the high energy of chemical bonds between the dissolved ammonia nitrogen molecules and water molecules in water, compared with other dissolved water molecules such as carbon dioxide and oxygen, ammonia nitrogen in low concentration ammonia nitrogen water is not easy to separate, so the removal effect of traditional aeration method is not good. Need to use some auxiliary means

Chemical methods (including: chemical precipitation method, stripping method, oxidation method, etc.) and biological methods have practical significance in the treatment of ammonia-nitrogen-containing wastewater, but the effect of low-concentration ammonia-nitrogen water in aquaculture is not good: biological removal requires certain The cultivation time of the biological flora is not suitable for fast-paced commercial transportation; the chemical removal method will release other chemical substances into the water body while removing ammonia nitrogen, which increases unforeseen risks
