Description

Technical Field

[0001] The utility model relates to wastewater treatment equipment, in particular to zero-discharge wastewater treatment equipment. Background Art

[0002] The so-called zero emission refers to the activities of infinitely reducing pollutant and energy emissions to zero. In terms of its content, zero emission means, firstly, controlling the energy and resource emissions that are inevitably generated in the production process and reducing them to zero; secondly, making full use of the energy and resources that are inevitably discharged and ultimately eliminating the existence of non-renewable resources and energy. Zero emission wastewater treatment equipment is a device used for zero wastewater discharge.

[0003] In the prior art, according to a Chinese patent, a patent with application number CN201921107606.X discloses a zero-emission wastewater treatment and recycling device, whose working principle is: by pouring wastewater into the first filter screen, filtering can be achieved through the first filter screen, and the filtered large waste can be removed by picking up the first filter screen through the snap-fit ​​assembly, and further filtering can be achieved through the second filter screen. For filtering small waste, the waste on the second filter screen is pushed into the small waste collection chamber through the waste removal assembly, and the metal particles are collected through the metal particle collection bottle. Disinfection and filtration are further achieved through the third filter screen, the filter belt and the active mud filter layer, and the electric heating plate is electrically heated by starting the electric heater.

[0004] The current zero-emission wastewater treatment equipment has certain defects when in use. The wastewater treatment equipment uses a filter to filter particulate impurities in the wastewater. After the filter filters the impurities, the filtered impurities accumulate on the filter. As the filter continues to filter, the impurities are blocked in the mesh of the filter, resulting in a reduction in the filtration area of ​​the filter, which in turn causes the filter to be unable to perform filtering work efficiently, thereby causing a reduction in the working efficiency of the wastewater treatment equipment. Therefore, improvements are now being made to zero-emission wastewater treatment equipment. Utility Model Content
