Domestic sewage recycling and reuse device

Technical Fields

The utility model relates to the technical field of domestic waste water recycling and reuse, in particular to a method for separating clear and turbid domestic waste water in a family dwelling unit, reclaiming clean water accounting for 30% of the total waste water and directly using it for toilet flushing, cleaning and watering in the unit. Hua's domestic sewage recycling and reuse device.

Background technique

Drawbacks of Traditional Sewage and Reclaimed Water Systems

The traditional sewage discharge system does not have the function of clearing and turbidity diversion. The "clear water" in the domestic wastewater and the real sewage are artificially mixed at the user end. After the mixed wastewater is concentrated, it flows to the sewage treatment plant through a long sewage system in a self-flowing manner, and flows to the sewage treatment plant. The mixed wastewater from the factory turned into black, smelly and greasy "sewage".

The sewage is treated by the sewage treatment plant, which separates the water in the mixed sewage from the dirt, viruses, grease and other harmful substances in the sewage, and turns it into "wastewater" that can be discharged.

Most of the reclaimed water used for flushing toilets is processed into reclaimed water by reclaimed water treatment plants using "waste water" as the water source. Then, through the long recycled water supply system, water is supplied to the building's recycled water supply system, and users take water from the building's recycled water supply system.

Some elderly people have already recycled domestic "clear water" for reuse. Since there is no convenient collection and reuse device, they have to use the most primitive method to collect and reuse the "clear water" in domestic wastewater.

waste of domestic water

The quality of tap water in most cities has reached the standard for direct drinking. However, many water projects in daily life do not require such high-standard water sources. For example, flushing toilets, cleaning windows and furniture, scrubbing tile walls, wiping floors, watering flowers and industrial water, the total water consumption is often much more than people's diet, but they consume precious high-standard water sources.

Directly reusable domestic wastewater

30% of domestic wastewater can be directly used for cleaning and watering flowers without treatment; another 30% of wastewater can be directly used for flushing toilets without treatment, or used for cleaning and watering flowers after simple treatment.

In the prior art, the traditional methods of artificially mixing and then trying to separate the dirt, viruses and other harmful substances in the sewage to obtain reclaimed water, as well as flushing toilets with directly drinkable tap water and making industrial cooling water are very unreasonable and wasteful.

The rapid increase of urban population and the rapid development of industry and commerce have brought enormous pressure to the water supply system. In recent years, the occurrence of abnormal climate and urban water shortages have become more frequent and the periods of water shortages have become longer and longer. People and the government have begun to pay attention to the recycling and reuse of domestic wastewater. The problem.

To sum up, it is necessary to design and provide a domestic sewage reuse solution and related devices that change the traditional sewage discharge and reclaimed water system.
