Problems solved by technology

At present, there are many sewage treatment schemes, but the best scheme recognized in the world is filter membrane sewage treatment. However, the pore size of the filter membrane is extremely small, 0.2 μm, and it is easy to be blocked by impurities in sewage.

Embodiment Construction

[0013] see Figure 1-3 , the specific embodiment adopts the following production process: 1. The waste water pretreated by physical precipitation etc. is first passed into the tower type biological filter for treatment; 2. The sewage is subjected to a laser scanning treatment; 3. The sewage is subjected to an ultrasonic treatment; 4. To irradiate the sewage once with ultraviolet rays. The above four processes are organically combined into one procedure, and the present invention is completed to control the organic pollutants, chroma, sulfide, alkalinity, etc. in the denim sewage.

[0014]The waste water that has been pretreated by physical precipitation in step 1 is first passed into the tower biofilter for treatment: the waste water has been pretreated to remove fine suspended matter such as cloth wool, thread ends, and fiber scraps, and the waste water mainly contains organic pollutants. , sulfide and other pollutants. Use a sewage pump 4 controlled by a frequency converte...

Abstract

The invention discloses a production process for denim sewage treatment and pretreatment, and relates to textile technology. The production process organically combines the following four flows: 1, introducing wastewater subjected to pretreatment such as physical sedimentation into a tower biological filter for treatment; 2, performing laser scanning treatment on the sewage for one time; 3, performing ultrasonic treatment on the sewage for one time; and 4, performing ultraviolet irradiation on the sewage for one time; the height of the tower biological filter is reduced greatly; a blast apparatus such as a blast blower is not needed; energy consumption and initial investment are reduced; the main flows of the process treatment are physical treatment flows, the sludge amount is reduced greatly, and the secondary pollution is prevented; and the investment is reduced and the production process is convenient to operate and manage.

Description

Technical field: [0001] The invention relates to a weaving process, in particular to a production process for denim sewage treatment and pretreatment. Background technique: [0002] Denim apparel is one of my country's important export textiles. The wastewater generated in its production process mainly comes from washing, dyeing and sizing processes. The main pollutants in wastewater are dyestuffs, sulfides, slurry and auxiliaries. Wastewater is characterized by strong alkalinity, high concentration of organic pollutants, high chroma, and high sulfide, and the quality and quantity of wastewater vary greatly. Pure biochemical or physicochemical treatment is difficult to meet the discharge requirements, and is considered to be one of the most difficult types of wastewater. Water quality also varies greatly due to different processing techniques. For example, the concentration of wastewater pollutants in the production of products such as mercerized blue, mercerized black, e...
