product description

Sewage profile:

The wastewater discharged during the production process of the washing industry contains a large amount of pollutants. The washing wastewater mainly includes washing wastewater, washing wastewater and spin-dry wastewater. Each wastewater has different characteristics: the washing wastewater contains surfactants, sodium tripolyphosphate, carboxymethyl cellulose, oil stains, dust particles, and various microorganisms. It has a cloudy appearance, a pH of 6.5 to 7.5, and a high suspended matter content Phosphate entering the water body will cause eutrophication of the water body. After the surfactant enters the water body, it will make the water vivid, plant poisoning and death, and solubilize some micro-pollutants in the water. The amount of cleaning wastewater is large, there is a small amount of foam, the suspended solids are small, the COD is small, and it is more transparent.

Process selection:

Taking the three-level discharge standard as an example, according to the characteristics of sewage water quality, the process of "air flotation machine + AO biochemical + chlorine dioxide disinfection" can be selected. (For other emission standard processes, please contact our technical staff)


Scope of application:

Hotel bed linen washing, hotel table linen washing, hospital bed linen washing, train bus bed linen washing, seat cover washing, etc.
