Cotton yarn dyeing wastewater treatment equipment

Abstract

The invention discloses a set of cotton yarn dyeing wastewater treatment equipment. The cotton yarn dyeing wastewater treatment equipment comprises a treatment box with the upper portion open, and wastewater treatment devices. The treatment box is square, a water inlet is formed in the front end of the treatment box, a drainage port is formed in the rear end of the treatment box, 2-8 rows of vertical tracks are arranged on the inner side of the treatment box, and the two sides of each wastewater treatment device are arranged in the corresponding tracks. Each wastewater treatment device comprises a square frame, wherein at least 10 layers of plastic wires are arranged in the frame, and the positions of the plastic wires in all the layers are staggered. A treatment bag is movably arranged in the middle of each wastewater treatment device, the heights of the treatment bags in the wastewater treatment devices from front to back are increased gradually, a hydraulic pump is arranged above the treatment box and connected with a support, and the support is connected with the upper edges of the frames through clamps. The cotton yarn dyeing wastewater treatment equipment is simple in structure, the dense plastic wires can intercept cotton yarns, fibers and impurities, and the filter efficiency is high; the treatment bags can regulate the PH value in an early stage, the wastewater treatment devices can be taken out to be cleaned, cost is reduced, the treatment efficiency is improved, the service life is long, resources can be saved, and the environment can be protected.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing equipment, and in particular relates to a cotton yarn printing and dyeing sewage treatment equipment. Background technique [0002] Cotton yarn printing and dyeing production needs to consume a lot of water resources. According to the current normal industry production level in my country, the annual water consumption reaches tens of millions of tons. The wastewater discharged generally contains a large amount of cotton yarn, fibers and impurities. If it is not treated, It will cause serious pollution to the ecological environment. In order to prevent the deposition and clogging of subsequent treatment units, filter devices are installed at the wastewater inlet to intercept fibers and impurities. However, the cost of purchasing existing filters is high and the failure rate is high. Self-made The filter device is not clean, and it needs to continue to filter in the subsequent process, whi...
