Description

Pretreatment device for wool washing wastewater

Technical Field

The utility model relates to the technical field of wastewater treatment, in particular to a wool washing wastewater pretreatment device.

Background

The primary source ‌ of industrial waste water from wool scouring is waste water produced by wool spinning enterprises during the wool scouring process. In the wool washing process, a large amount of water is used for washing wool, and impurities such as lanolin, sheep sweat, sheep manure, grass scraps, short wool, sediment and the like are mixed into the washing water to form high-concentration organic sewage. If the floats, the minced meat and the wool in the wastewater enter the subsequent treatment process without treatment, the lifting pump is blocked, a great amount of wool is accumulated in the regulating tank, and the normal operation of the sewage treatment system is seriously influenced, so that a pretreatment device is required to be arranged before the wastewater enters the regulating tank. In recent years, a great deal of experimental research work is carried out on the treatment of wool washing wastewater by some domestic wool washing factories and design and research institutions, and some research results are obtained, but ideal treatment schemes ‌ popularized in actual production are still lacking.

The most common solution at present is to arrange a grid before the wastewater enters the regulating tank to intercept suspended matters and floaters in the wastewater so as to ensure the normal operation of the subsequent treatment process. The method can effectively remove suspended matters and floaters in the wastewater, but animal hair in the wastewater still passes through the grille gaps and cannot be effectively removed, and if the smaller grille gaps are used for blocking the hair, the grille gaps are easy to block, and the filtering is affected.

Therefore, it is necessary to provide a pretreatment device for wool washing wastewater to solve the above problems.
