Example Embodiment

[0025] Example 1

[0026] The tap water from the faucet 6 becomes domestic waste water after being used in life. The domestic waste water is introduced into the water purifier, and first flows into the non-stick oil filter module 1. The non-stick oil filter module uses environmentally friendly bamboo fiber, and the residence time is controlled to 5 minutes. After filtration, the effluent flows into the activated carbon filter assembly 2 for filtration treatment. The residence time is 10 minutes, which is more than domestic wastewater discharged from the overflow pipe into the drainage pipe network 5, 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, and the residence time of wastewater in the ozone contact tank is 10min. Finally, the effluent is collected in the water purification tank 4 and can be reused as household flushing water through the action of the water pu...

[0027] Example 2

[0028] Introduce the domestic wastewater into the water purifier, first flow into the non-stick filter assembly 1, control the residence time to 10min, and perform filtration treatment. More than domestic wastewater is discharged from the overflow pipe into the drainage network 5, and then the effluent flows into the activated carbon filter assembly 2. Perform filtration treatment with a residence time of 5 minutes, and then the effluent flows into the ozone disinfection and sterilization module 3 for disinfection and sterilization. The dosage of ozone is 10mg / L, the residence time of wastewater in the ozone contact tank is 5 minutes, and finally the effluent gathers in The water purification tank 4 is reused as water for washing the mop, and the excess domestic wastewater is directly discharged from the pipe network.

[0029] Example 3

[0030] Introduce the domestic wastewater into the water purifier, first flow into the non-stick oil filter assembly 1, control the residence time to 10min for filtration treatment, then the effluent flows into the activated carbon filter assembly 2 for filtration treatment, the residence time is 5min, and then the effluent flows into the ozone for disinfection and sterilization Component 3 is disinfected and sterilized. The dosage of ozone is 5mg / L, and the residence time of wastewater in the ozone contact tank is 10min. Finally, the effluent is collected in the water purification 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...
