Abstract

The invention discloses a method for treating textile waste water. The textile waste water is screened and filtered through a grid, and after being treated in a neutralization tank and a balance tank, it is transferred to an adsorption tank, and the blast furnace slag adsorbent is used for adsorption treatment for 12h to 16h. Lightweight ceramsite was prepared from solid waste for later use; then it was transferred to the catalytic degradation tank, and under the irradiation of ultraviolet light, carbon-supported Co 2 o 3 Catalyst, carry out the catalytic degradation reaction for 1h~4h; transfer the textile wastewater treated by the catalytic degradation pool to the gravel pool for filtration for 10h~12h, and then discharge it into the clear water pool through the filter screen, and reuse it in the textile workshop. The textile wastewater treatment method of the invention can effectively remove pollutants in the textile wastewater, reduce treatment costs, and can reuse waste.

Description

technical field [0001] The invention relates to the technical field of multistage treatment of waste water, in particular to a treatment method for textile waste water. Background technique [0002] Textile wastewater contains a large amount of organic matter, which consumes a large amount of dissolved oxygen when degraded in water. Dissolved oxygen in water is reduced, which will harm aquatic organisms. When the dissolved oxygen is exhausted, anaerobic decomposition occurs, causing the water to turn black and smelly. In addition, pigments, pigments, suspended solids, sulfides, precious metals, etc. in wastewater can also cause water deterioration. This kind of pollution has low concentration, wide distribution, harms the ecological environment and threatens human health, so it is urgent to deal with this kind of wastewater. Textile wastewater treatment methods include physical and chemical methods, biochemical methods, electrochemical methods, chemical methods, photochem...
