Description
Technical field
The present invention relates to a kind of methods of water-treatment technology field, specifically utilize in ultrafiltration removal eutrophication water
The technology of algae.
Background technology
Drinking Water in China pollution of waterhead problem getting worse, water quality often will appear high algae characteristic, cause water body to generate apparent
Peculiar smell.And the water purification ability of existing water supply common process, the water quality index test analysis being discharged by water factory, prior art
It is limited to the purification of water quality ability at the water source by algae pollution.The removal of coagulation, the single technique of disinfection for extracellular algal toxin
Rate maintains 18% to 44%, and sand filtration does not have removal effect, common process averagely to remove the removal effect of extracellular algal toxin
Rate is only 28%.Monitoring data also illustrate that prior art for smell substance almost without effect.
Ultrafiltration is gradually recognized as third generation urban drinking water purification technique, can since ultrafiltration is mainly sieving actoion
With under the premise of not destroying alga cells structure, the algae in gentle removal water body, and for the removal effect of algae
Well.
In order to further ensure water safety, it is a kind of good to remove the algae in eutrophication water using ultrafiltration
Technical measures.

Class is a technical solution innovated very much.The present invention is achieved by the following technical solutions, specifically comprises the following steps：
1. device is mainly by raw water box (2), cartridge filter (3), booster pump (4), hyperfiltration membrane assembly (5), booster pump
(6), water production tank (7).Agitating device is wherein set in raw water box (2), water production tank (7), ensures water quality isotropic stable；
2. hyperfiltration membrane assembly (5) is filtered using dead section or cross-flow filtration, the visual water quality situation of membrane module uses plural serial stage
Operation is setting value using PLC Frequency Converter Control ultra-filtration fluxes；
3. depending on raw water quality situation online mistake can be constituted with membrane module in raw water box (2) dosing coagulant or Powdered Activated Carbon
Filter, to further increase the removal rate of algae.
Description of the drawings
The following further describes the present invention with reference to the drawings.
Fig. 1 is the process flow chart that ultrafiltration removes algae in eutrophication water, wherein：1. raw water；2. raw water box；3. protecting

Specific implementation mode
It elaborates below to the embodiment of the present invention：The present embodiment is carried out lower based on the technical solution of the present invention
Implement, gives detailed embodiment, but protection scope of the present invention is not limited to following embodiments.
Embodiment 1
Fig. 2~3 are using certain micro-polluted surface lake water as raw water, and directly filtering removes algae example in eutrophication water.
The water quality of detection in every 5 days, more fully to evaluate for the treatment effect under algae fluctuation of concentration in raw water.Diatom is that this is micro-
The Main Algae in terrestrial reference lake water is polluted, raw water, the diatom concentration in hyperfiltration membrane assembly production and removal rate are as shown in Fig. 2, ultrafiltration
Membrane module reaches 82% to 95% for the removal rate of diatom, it can be seen that ultrafiltration is good for the removal effect of diatom.Algae is green
Albumen is a kind of distinctive pigment of cyanobacteria, and detecting its content can be as an index of blue alga biomass.Raw water, ultrafiltration membrane group
Phycocyanin concentration and removal rate in part production is as shown in figure 3, hyperfiltration membrane assembly reaches 89% for the removal rate of phycocyanin
To 94%, it can be seen that ultrafiltration is good for the removal effect of phycocyanin.To sum up, in the case that directly filter, ultrafiltration for
Algae has good removal effect in water, suitable for removing the algae eutrophication water.
Embodiment 2
Fig. 4~5 are the algae in filtering removal eutrophication water after In-line coagulation using certain micro-polluted surface lake water as raw water
Example (coagulant charging quantity is 4mg/L (in terms of Al)).The water quality of detection in every 5 days, the diatom in raw water, hyperfiltration membrane assembly production
Concentration and removal rate are as shown in figure 4, hyperfiltration membrane assembly reaches 95% to 99% for the removal rate of diatom, it can be seen that ultrafiltration pair
It is outstanding in the removal effect of diatom.Raw water, the phycocyanin concentration in hyperfiltration membrane assembly production and removal rate are as shown in figure 5, ultrafiltration
Membrane module reaches 88% to 93% for the removal rate of phycocyanin, it can be seen that ultrafiltration is good for the removal effect of phycocyanin
It is good.To sum up, after In-line coagulation filtering have good removal effect for algae in water, suitable for raw water algae concentration it is higher or
The case where wishing removal effect higher removes the algae in eutrophication water.
It is enlightenment with above-mentioned desirable embodiment according to the present invention, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to determine its technical scope according to right.
