Problems solved by technology

[0002] The cloth printing and dyeing industry is one of the pillars of the current economic development, but a lot of sewage will be produced in the cloth printing and dyeing, which will cause very serious environmental pollution. Even if the treated sewage is discharged, it will still make the water in the river eutrophic. As a result, plants such as water hyacinth and blue-green algae grow wildly, affecting the entire ecosystem, and many manufacturers choose not to treat sewage and discharge it quietly for petty profits

Embodiment 1

[0013] The cloth wastewater treatment method of the present invention comprises the following steps: (1), discharging the wastewater into a grid tank to filter and remove impurities; (2), bleaching the remaining impurity-free wastewater and then adding a coagulant for treatment; (3) Dehydration treatment of impurities and impurities formed after adding coagulant treatment; (4), introduction of filtered wastewater into the ozone oxidation tank, through the strong oxidation of ozone, the organic matter that is difficult to degrade is further degraded, and Utilize the decolorization performance of ozone to ensure the chromaticity of the effluent; (5) Discharge the decolorized and degraded waste water that meets the standard into the storage pool.

[0014] The temperature in the grid tank was controlled at 30 °C.

[0015] The coagulant includes 5g of aluminum sulfate, 2g of polyaluminum chloride, 10g of ferric chloride, 8g of ferrous sulfate and 5g of magnesium carbonate by weight...

Abstract

The invention discloses a cloth wastewater treatment method which includes the steps: (1) removing impurities by filtering; (2) adding coagulants in bleaching; (3) dewatering the impurities again; (4)performing ozone degradation and discoloration; (5) storing wastewater reaching standards. The cloth wastewater treatment method has the advantages that cloth wastewater is treated by the coagulants,good wastewater treatment effects can be achieved, generated condensation products are firm, good in precipitation performance and decolorizing and oil removing effect and not easy to destroy, bleaching treatment is performed in the treatment process, the filtered wastewater is subjected to strong oxidation treatment, the impurities are dewatered, wastewater treatment effects of the operation steps are better than those of common operation, efficiency is high, and pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a cloth wastewater treatment method. Background technique [0002] The cloth printing and dyeing industry is one of the pillars of the current economic development, but a lot of sewage will be produced in the cloth printing and dyeing, which will cause very serious environmental pollution. Even if the treated sewage is discharged, it will still make the water in the river eutrophic. As a result, plants such as water hyacinth and blue-green algae grow wildly, affecting the entire ecosystem, and many manufacturers choose not to treat sewage and discharge it quietly for petty profits. Therefore, it is very necessary to set up a waste water treatment process with low cost and effective utilization of waste water. Contents of the invention [0003] In order to solve the above technical problems, the present invention is solved through the following technical solutions:...
