Embodiment 1
[0029] Such as figure 1 As shown, the reservoir water treatment process provided by the present invention involves five main treatment equipments, which are respectively: integrated water purifier 1, intermediate pool 2, activated carbon filter 3, ultrafiltration equipment 4 and clear water pool 5; Also connected with pipeline mixer 6 on the upstream pipeline of water purifier 1.
[0030] Among them, the pipeline mixer 6 is provided with a dosing inlet 61 for adding flocculant, and the raw water (that is, the reservoir water to be treated) first passes through the pipeline mixer 6 on the pipeline to mix with the flocculant, and then enters the whole body through the water inlet 11. In the water purifier 1.
[0031] The integrated water purifier 1 is composed of a flocculationsedimentation tank 12 and a filter tank 13; the integrated water purifier 1 is provided with a water inlet 11 communicated with the pipeline mixer 6 and a water outlet 14 communicated with the intermedia...
Embodiment 2
[0051] This embodiment also provides the process of using the same processing equipment and structure of Embodiment 1 to process the reservoir water, and the specific steps are as follows:
[0052] (1) The reservoir water flows through the pipeline mixer, mixes with the flocculant injected in the pipeline mixer, passes into the integrated water purifier together after mixing, carries out flocculation reaction, sedimentation and filtration, obtains treated water I;
[0053] Among them, the water quality of the raw water of the reservoir is as follows: total coliforms=30CFU / 100mL, number of colonies=213CFU / 100mL, Giardia=4 / 10L, Cryptosporidium=2 / 10L, turbidity=5NTU, COD Mn (with O 2 Count)=15mg / L.
[0054] The flocculant is polyaluminum chloride, and the dosage is 25g / m 3 ; The processing capacity of the integrated water purifier is 70m 3 / h; the length of the diversion inclined pipe in the inclined pipe settlement area is 1000mm, and the inclination angle is 60°; the particl...
Embodiment 3
[0061] This embodiment also provides the process of using the same processing equipment and structure of Embodiment 1 to process the reservoir water, and the specific steps are as follows:
[0062] (1) The reservoir water flows through the pipeline mixer, mixes with the flocculant injected in the pipeline mixer, passes into the integrated water purifier together after mixing, carries out flocculation reaction, sedimentation and filtration, obtains treated water I;
[0063] Among them, the water quality of the raw water of the reservoir is as follows: total coliforms=75CFU / 100mL, number of colonies=321CFU / 100mL, Giardia=5 / 10L, Cryptosporidium=6 / 10L, turbidity=9NTU, COD Mn (with O 2 Count)=20mg / L.
[0064] The coagulant is polyaluminum chloride, and the dosage is 15g / m 3 ; The processing capacity of the integrated water purifier is 30m 3 / h; the length of the diversion inclined pipe in the inclined pipe settlement area is 700mm, and the inclination angle is 50°; the particle ...

Abstract
The invention discloses a reservoir water treatment process which comprises the following steps: enabling reservoir water to flow through a pipeline mixer, mixing the reservoir water with a flocculating agent injected into the pipeline mixer, introducing the mixture into an integrated water purifier together, and performing flocculation reaction, precipitation and filtration to obtain treated water I; introducing the treated water I into an intermediate water tank for standing, and pumping the treated water I into an activated carbon filter for adsorption treatment to obtain treated water II;and introducing the treated water II into ultrafiltration equipment for filtration treatment, then introducing the treated water II into a clean water tank, and carrying out disinfection treatment toobtain discharged water. According to the treatment process disclosed by the invention, five treatment units including the integrated water purifier, the intermediate water tank, the activated carbonfilter, the ultrafiltration equipment and the clean water tank are combined; suspended particles, turbidity, chromaticity, bacteria and organic pollutants which are difficult to remove and are generated by decomposition of plants or microbial metabolism in reservoir water are effectively treated, so that discharged water reaches the standard of domestic drinking water.
Description
technical field [0001] The invention relates to the technical field of water treatment, in particular to a treatment process for reservoir water. Background technique [0002] With the improvement of living standards, people's water quality requirements for drinking water are gradually increasing. At present, most of drinking water comes from surface water. Reservoirs are artificial lakes that store a large amount of water resources. Usually, dams are built on the river to store river water. The turbidity of the water is relatively low, and it contains a small amount of heavy metal ions. The content of organic matter in the water is high, mainly including alkanes and unsaturated hydrocarbons , benzene series and heterocyclic compounds, most of these organic compounds are produced by plantdecomposition or microbial metabolism. [0003] Conventional water treatment processes mainly include coagulation, flocculation, precipitation, filtration, disinfection and other processe...
