Domestic sewage treating and recycling device

Abstract

The invention discloses a domestic sewage treating and recycling device. The domestic sewage treating and recycling device is characterized in that an asbestos net filtering layer is arranged in a first slot; a quartz sand filtering layer is arranged in a second slot; an anthracite filtering layer is arranged in a third slot; a sewage monitor is arranged at the bottom end of the third slot; a heater is arranged at the bottom end of a water purifier; a distilled water adsorber is arranged at the top end of the heater; a reflux siphon is arranged at the bottom end of the sewage monitor; a pure water pipe is arranged on one side of a filter; a pure water valve is arranged at the inner end of the pure water pipe and electrically connected with the sewage monitor. The domestic sewage treating and recycling device is suitable for urban life and can safely and effectively recycle domestic sewage, the treated water resource is safe and healthy and can be domestically used again, so that water resource waste is greatly reduced, and repeating utilization factor of the water resource is increased.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a domestic sewage treatment and recycling device. Background technique [0002] Household sewage is one of the main sources of water pollution in China's urban areas. Therefore, the demand for sewage and the health issues related to the reuse of sewage for non-drinking purposes need to be studied. The country's economic development and the improvement of people's living standards require To increase water resources, there is an urgent need for efforts to develop unconventional water sources, and treated water discharged to water bodies (rivers, lakes, groundwater for domestic and industrial and agricultural water supply) has become an important part of the country's unplanned fresh water supply. Therefore, sewage It must be properly treated to remove and reduce harmful substances to prevent harm to water bodies. In fact, the reuse of household sewage has become a very important issue ...

[0002] Household sewage is one of the main sources of water pollution in China's urban areas. Therefore, the demand for sewage and the health issues related to the reuse of sewage for non-drinking purposes need to be studied. The country's economic development and the improvement of people's living standards require To increase water resources, there is an urgent need for efforts to develop unconventional water sources, and treated water discharged to water bodies (rivers, lakes, groundwater for domestic and industrial and agricultural water supply) has become an important part of the country's unplanned fresh water supply. Therefore, sewage It must be properly treated to remove and reduce harmful substances to prevent harm to water bodies. In fact, the reuse of household sewage has become a very important issue in the development, utilization and protection of water resources in the country. Since the 1980s, China has started to reuse sewage Great efforts have been made in development. After proper treatment, waste water can be reused for industry and irrigation (including crops, golf courses, parks and other entertainment venues, etc.), and the treated water is also used for recharging groundwater. Wastewater reuse is limited in savings An important measure of high-quality drinking water, the Chinese government gives strong support to the reuse of recycled sewage as non-drinking water, because there are many bad water-wasting habits in ordinary households, such as flushing cigarette butts and fine waste with flush toilets; washing first Peel potatoes and carrots; pick vegetables after rinsing; open the door, answer the phone, and change TV channels without turning off the faucet during water use; Leaving the faucet open from time to time causes the loss of water resources and becomes domestic wastewater. At present, the domestic sewage treatment technology is not perfect, and the used sewage cannot be reused reasonably, which wastes a lot of water resources.
