The textile industry is a huge industry, and a large amount of wastewater is generated during the production process. Due to the large amount of organic compounds and pollutants such as dyes, wastewater has caused serious pollution to the water environment. In order to reduce environmental pollution, relevant experts and researchers are committed to the research and development of zero discharge technology for textile wastewater.
Textile wastewater zero discharge technology refers to the complete removal of pollutants in wastewater through a series of process means and devices, so as to achieve efficient treatment of wastewater and finally achieve the goal of zero discharge.
Through physicochemical means, we can use filtration, sedimentation and adsorption technologies to remove pollutants such as suspended solids and pigments from wastewater. The filtration device can intercept larger solid particles, and the sedimentation device can precipitate the substances with high particle density, and at the same time of filtration and precipitation, the adsorption material is used to adsorb the organic pollutants in the wastewater, so as to reduce the content of organic pollutants.
Through biological treatment, we can use microorganisms to degrade and purify wastewater. Biological treatment is a low-energy, environmentally friendly and economical treatment method that uses the metabolic activity of microorganisms to degrade organic pollutants and convert them into harmless substances. Using bioreactors, aeration devices and aeration methods, the organic matter in wastewater can be rapidly degraded, so as to achieve the requirement of zero discharge.
