Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a sewage treatment device for dyeing straw and willow products. Background Art

[0002] At present, the treatment of wastewater from dyeing straw and willow products is a complex process involving multiple steps, the main purpose of which is to remove harmful substances from the wastewater so that it meets the discharge standards. The following is a possible wastewater treatment process:

[0003] Pretreatment: First, the straw and willow dyeing wastewater is pretreated, including the removal of large particles of impurities and suspended matter. This can be done through physical methods such as grilles, screens, etc.

[0004] Adjustment and neutralization: Next, adjust the pH value of the sewage to a range suitable for subsequent treatment. At the same time, chemical agents can be added for neutralization reaction to remove some harmful substances in the sewage.

[0005] Biological treatment: Biological treatment is the core step of sewage treatment, including aerobic treatment and anaerobic treatment. In aerobic treatment, the metabolic activity of microorganisms in the presence of oxygen is used to decompose organic matter in sewage into harmless substances. Anaerobic treatment is to further degrade organic matter through the action of anaerobic microorganisms under oxygen-free conditions.

[0006] Advanced treatment: After biological treatment, sewage may still contain some difficult-to-degrade substances and trace amounts of harmful substances. At this time, it can be further purified through advanced treatment, such as activated carbon adsorption, membrane separation, advanced oxidation and other technologies.

[0007] When the wastewater generated by dyeing straw and willow products can be treated through the above-mentioned treatment steps, heavy metals such as chromium, lead, mercury, etc. are used in the printing and dyeing process. These heavy metals are difficult to degrade in general biochemical methods, so they can exist in the natural environment for a long time and may endanger human health through the food chain and other means. In particular, the amount of heavy metal chromium used in printing and dyeing is relatively large. For example, potassium dichromate is often used as an oxidant and mordant in the dyeing process, and the preparation of printing rollers also consumes a large amount of chromium. Therefore, the dyeing wastewater contains heavy metals, and the efficiency of treating the wastewater only through physical filtration and other steps is low, and it is impossible to efficiently complete the treatment of particulate matter, suspended matter and heavy metal ions in the wastewater. In view of this, we propose a straw and willow product dyeing wastewater treatment device. Summary of the invention

[0008] The purpose of the present invention is to overcome the shortcomings of the prior art, meet the actual needs, and provide a straw and willow product dyeing wastewater treatment device to solve the current printing and dyeing process.
