specific Embodiment approach 2

[0040] Embodiment 2: This embodiment differs from Embodiment 1 in that: the particle size of the granular activated carbon is 1.2-5 mm. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0041] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the quartz sand is modified quartz sand, and the specific preparation method is as follows:

[0042] Mix quartz sand with distilled water and stir for 1-2 hours, then add citric acid and stir for 3-5 hours, centrifuge, wash, and dry to obtain activated quartz sand;

[0043] Add β-cyclodextrin and dimethyl sulfoxide to the activated quartz sand, stir and react in a water bath at 60°C for 3 to 12 hours, after the reaction is completed, wash the product with absolute ethanol, dry it in a vacuum oven for 24 hours, and The modified quartz sand is obtained after being pulverized by a high-speed stirring pulverizer. Others are the same as in the first embodiment.

[0044] In this embodiment, β-cyclodextrin is used to modify the quartz sand, which can improve the removal effect of the quartz sand on various heavy metals. Drinking water containing heavy metals was treated for 24 h...

Abstract

The invention discloses an intelligent secondary water supply treatment device and a secondary water supply treatment method, and aims to solve the problems that the existing secondary water supply treatment method and equipment are high in cost, and the generation amounts of HKs, CH, THNMs and the like in treated effluent are increased. The device comprises a secondary water supply storage container, a regulating water tank, an aeration device, an ozone generation device, a quartz sand filter, a composite activated carbon filter, a tail gas destruction device, a membrane filtration device and a water production tank, a water outlet of the secondary water supply storage container is connected with the adjusting water tank, a water outlet of the adjusting water tank is connected with the quartz sand filter through the aeration device, a water outlet of the quartz sand filter is connected with the composite activated carbon filter, a water outlet of the composite activated carbon filter is connected with the tail gas destroying device, and the tail gas destroying device is sequentially connected with the membrane filtering device and the water producing tank. The problem of secondary pollution of drinking water caused by water conveying of a water supply pipe network and water storage of a secondary water supply system can be effectively solved. The device is applied to the field of secondary water supply treatment.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to an intelligent secondary water supply treatment device and a method for using the device for secondary water supply treatment. Background technique [0002] With the improvement of the living standard of Chinese residents, residents pay more and more attention to the safety of drinking water. With the development of industry, a large number of organic and inorganic pollutants are discharged into natural water bodies, and the safety of drinking water in our country is not optimistic. Coupled with the aging phenomenon of the municipal pipe network, secondary water supply equipment or management and other reasons, the quality of tap water used by residents in our country has deteriorated seriously, causing microorganisms, turbidity, Fe, Mn, Ca, Mg and other elements to exceed the standard, restricting the development of people's livelihood. [0003] The patent (CN 111851651 A) disclo...
