Device for circulating and treating sewage of washing machine

Abstract

The invention discloses a device for circulating and treating sewage of a washing machine. The device comprises a sewage holding tank, a filtering part, a purified water storage part and a control device, wherein the filtering part comprises a body part which is communicated with another chamber of the sewage holding tank through a first tube body, a first filtering part, a second filtering part, a third filtering part, a fourth filtering part and a fifth filtering part which are sequentially arranged inside the body part from high to low of the body part, a water quality monitoring sensor which is arranged at the bottom of the body part, and a return water tube of which two ends are respectively connected with the top and the bottom of the body part; the purified water storage part comprises a purified water tank which is connected with the top of the body part, and an activated carbon adsorption membrane and a far-infrared mineralized sphere filter element which are sequentially arranged inside the purified water tank from high to low of the purified water tank; a second tube body is communicated between the bottom of the body part and the top of the purified water tank; the control device comprises a controller, a display which is electrically connected with the controller, and buttons which are electrically connected with the controller. The device is simple in structure, and a very good use effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to a washing machine sewage recycling treatment device. Background technique [0002] my country has a large population, but per capita fresh water resources are only a quarter of the world's average. With the increasing population and economic scale and the continuous improvement of urban and rural living standards, the increase in water demand and global climate change and environmental pollution The contradiction between the scarcity of fresh water resources has become more and more acute. Especially in North China, Northwest China and some megacities, water shortages or even water cuts occur from time to time, which has obviously restricted the living safety of residents. Therefore, a reasonable domestic sewage recycling treatment system has emerged as the times require, but the investment in the existing treatment system is huge, and the range of reused water to be t...
