Industrial sewage treatment equipment

Abstract

The invention discloses industrial sewage treatment equipment. The industrial sewage treatment equipment comprises a casing, wherein a mud and water separating device and a nanofiltration membrane filtering net are sequentially and fixedly arranged in the casing from top to bottom; a glass hollow plate is fixedly arranged at the periphery of the side wall of the casing by a hinge between the mud and water separating device and the nanofiltration membrane filtering net; ultraviolet sterilizing lamps are uniformly distributed in the glass hollow plate at equal intervals; the top part of the casing is clamped with a top cover in a sealing way; a liquid inlet hole is formed in the center of the top cover; a slag discharge door is arranged at the side wall of one end, near the mud and water separating device, of the casing; a water drain pipe is arranged at the side wall, near the bottom end, of the casing; a dirt discharge pipe is arranged under the mud and water separating device, and isembedded and communicated with a plurality of filtrate funnels; the other end of the dirt discharge pipe extends out of the casing, and is communicated with a dirt sucking and water purifying device;the dirt discharge pipe is sequentially and fixedly connected with a dirt discharge pump and a valve; a water outlet of the dirt sucking and water purifying device is communicated with one end of a reflux pipe, and the other end of the reflux pipe is communicated with the bottom part of the casing.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to industrial sewage treatment equipment. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for drainage or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. field, and more and more into the daily life of ordinary people. [0003] Moreover, in people's daily life, domestic wastewater contains a large amount of sludge, organic matter and impurities, etc., and domestic wastewater is directly discharged into the environment, which seriously affects the surrounding environment. Therefore, the sewage treatment device is an important equipment, and the existing sewage In the treatment tank, when the sewage enters the tank for precipitation, the sewage directly ent...
