Self-cleaning sewage treatment device

Abstract

The invention discloses a self-cleaning sewage treatment device. The self-cleaning sewage treatment device comprises a tower. A suspended-solid removing box is connected to the tower through a pipeline. A water inlet is arranged at the top of the tower. A horizontal splitter plate is arranged on the inner upper part of the tower. Two rotating plates with arc-shaped front ends are arranged on the splitter plate, and are rotationally connected with the splitter plate through rotating shafts. The rotating shafts are driven to rotate by a motor. A primary separation net and a secondary separationnet are arranged on the splitter plate. The self-cleaning sewage treatment device has the advantage that the double separation nets are arranged on the inner upper part of the tower, and a cleaner isarranged on each separation net correspondingly, so that solid impurities are cleaned automatically while solid and liquid separation of sewage is realized, and continuous treatment efficiency is improved greatly; through the suspended-solid removing box, residual small suspended solids are subjected to slag scrapping treatment, and accordingly, the amount of pollutants in the treated sewage is much lower than national emission standards; treatment efficiency is high, time is short, and the self-cleaning sewage treatment device is suitable for vigorous popularization.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to a self-cleaning sewage treatment device. Background technique [0002] In modern life, especially with the deepening of urbanization, the living density of the population is increasing, and the domestic wastewater and some other sewage impurities are also increasing. At the same time, in order to be in the existing living environment More space is found, so urban construction is also increasingly developing towards high-rise buildings and underground buildings, but the problem of urban pollution, especially the problem of domestic sewage, is also becoming more and more serious. [0003] In order to deal with the sewage problem, a lot of sewage treatment equipment have emerged. At present, most of them use a single tank for chemical neutralization or sedimentation treatment. However, the current situation is that the sewage contains a large amount of solid waste. A single trea...

[0003] In order to deal with the sewage problem, a lot of sewage treatment equipment have emerged. At present, most of them use a single tank for chemical neutralization or sedimentation treatment. However, the current situation is that the sewage contains a large amount of solid waste. A single treatment method will cause long treatment time and The possibility of secondary pollution is high, and solid waste gas will also cause damage to mechanical equipment such as mixers used to mix neutralizers, so the current equipment cannot meet the existing needs
