Embodiment 1

[0026] The tap water flowing out of the faucet 6 becomes domestic wastewater after being used for daily life. The domestic wastewater is introduced into the water purifier, and first flows into the non-stick filter assembly 1. Environmentally friendly bamboo fiber is used in the non-stick filter assembly, and the residence time is controlled to be 5 minutes. Carry out filtration treatment, then the effluent flows into the activated carbon filter assembly 2 for filtration treatment, the residence time is 10min, more than domestic waste water is discharged into the drainage pipe network 5 from the overflow pipe, and then the effluent flows into the ozone disinfection and sterilization assembly 3 for disinfection and sterilization For treatment, the dosage of ozone is 3mg / L, the residence time of wastewater in the ozone contact tank is 10min, and finally the effluent is collected in the clean water tank 4, and can be reused as household flushing water by the action of the water pum...

Embodiment 2

[0028] The domestic waste water is introduced into the water purifier, and first flows into the oil-free filter assembly 1, and the residence time is controlled to be 10 minutes for filtration treatment, and the excess domestic waste water is discharged from the overflow pipe into the drainage pipe network 5, and then the effluent flows into the activated carbon filter assembly 2. Carry out filtration treatment with a residence time of 5 minutes, then the effluent flows into the ozone disinfection and sterilization component 3 for disinfection and sterilization treatment, the dosage of ozone is 10 mg / L, the residence time of wastewater in the ozone contact tank is 5 minutes, and finally the effluent is gathered in In the clean water tank 4, it is reused as water for rinsing and washing the mop, and unnecessary domestic waste water is directly discharged from the pipe network.

Embodiment 3

[0030] The domestic wastewater is introduced into the water purifier, firstly flows into the oil-free filter assembly 1, and the residence time is controlled to be 10 minutes for filtration treatment, then the effluent flows into the activated carbon filter assembly 2 for filtration treatment, the residence time is 5 minutes, and then the effluent flows into ozone for disinfection and sterilization Component 3 is for disinfection and sterilization treatment, the dosage of ozone is 5mg / L, the residence time of wastewater in the ozone contact tank is 10min, and finally the effluent is collected in the clean water tank 4 and reused as household flushing water.

Abstract

The invention discloses a method for reuse and treatment of household reclaimed water, and the method belongs to the field of household water treatment methods. The treatment steps are as follows: domestic waste water flows into an oil-repellent filter component for the filtration treatment; outlet water from thereon flows into an activated carbon filter component for the filtration treatment; the outlet water therefrom flows into an ozone disinfection sterilization component for the disinfection and sterilization treatment; and the outlet water therefrom is collected in a clean water tank and reused as household toilet-flushing water. The domestic waste water is processed by the method, according to the characteristic that the household toilet-flushing water has different requirements on the reused water quality, thereby not only ensuring the reused water quality and the sanitary conditions, but also facilitating the maintenance and the replacement of equipment and being easy to spread the technology.

Description

technical field [0001] The invention relates to a method for domestic water purification, in particular to a method for domestic reclaimed water reuse treatment. Background technique [0002] At present, the shortage of water resources and the discharge of pollutants have become the restrictive factors of my country's economic and social development. Attention has been paid to it, and the development of household small-scale water purification equipment has gradually become a research hotspot. However, due to unstable reuse water quality and poor sanitation conditions of domestic water purification equipment, the process of water purification equipment is complicated, and maintenance and replacement are inconvenient, which affects the popularization and application of the technology. [0003] Household domestic wastewater generally refers to the water used for washing vegetables, dishes, face, bathing, and laundry, which accounts for the vast majority of domestic water consu...
