Description
Technical field
The invention belongs to water treatment fields, are related to water treatment facilities, and in particular to a kind of static state used in water factory is mixed
Box-like deep-well pressurization, which is strengthened, removes cyanobacteria water treatment facilities.
Background technique
Bloom blue algae is the problem in drinking water treatment, and bloom blue algae has air bag into the cell, provides buoyancy for algae, makes
Algae cannot sink, and be not easy by coagulating sedimentation technology removal conventional in water factory.Algae air bag can resist the outer of 0.4-0.7MPa
Boundary's pressure, if ambient pressure exceeds this pressure, air bag just irreversibly ruptures.Currently, waterworks is in processing cyanobacteria
When device include water supply pump, water treating pond (being generally made of mixing pit, reaction tank, sedimentation basin) and chemicals dosing plant etc., supply water
Pump is supplied water by water pipe to mixing pit, and algicide and coagulant are added into mixing pit or static mixer, contains for chemicals dosing plant
Algae water mixed in mixing pit, reaction tank, sedimentation basin, is reacted and precipitation process.Algicide is firstly added to kill algae,
It adds a large amount of coagulant to be adhered to each other other impurities particle in algae particle and water, increases algae particle weight, then
Precipitating removal.The algicide added in source water has the strong oxidizers such as chlorine, potassium permanganate, ozone, and coagulant has aluminum sulfate, chlorine
Change iron, aluminium polychloride etc..There are many problems, algicides to come into full contact with 20min or more with algae for this method for treating water,
After algae is killed, frustule rupture, the dissolved matters such as algae toxin and cell liquid leak into water, and algae toxin has very strong poison
Property, algae solution can also be reacted with subsequent Water Disinfection agent generates carcinogen.Algicide has strong corrosion to make water supply line
With.For coagulating sedimentation there is still a need for adding a large amount of coagulant can just algae be made to precipitate, dosage 40mg/L or more be at high cost after killing algae,
And effect is undesirable.
Chinese invention patent (publication No.: 104933221 A of CN) discloses a kind of " Kenic HEV static mixer efficiency
With pressure drop calculation method ", which provides a kind of static mixer blades efficient design method, but the static mixing

4 tops, are discharged by outlet pipe 1-6.Such process, making the Microcystis aeruginosa in water, air bag is crushed under a certain pressure, and density increases
Greatly, start to sink；Medicament for matching (coagulant, strong oxidizer and adsorbent etc.) effect simultaneously is further subsequent technique removal
Algae in water improves water quality and provides extraordinary preact.
Due to containing a small amount of mud in raw water, bottom has deposition after running a period of time, needs to be rinsed.Flushing starts
When, the 4th valve 3-9 on third valve 3-7 and draining sludge pipe 3-4 on connecting tube 3-8 is closed, and is rinsed on water inlet pipe 3-3
The first valve 3-2 and vertical flushing dredging tube 3-6-1 on the second valve 3-5 open, high pressure washing pump 3-1 by rinse intake
Pipe 3-3 water suction, water enter high pressure washing pump 3-1 by flushing water inlet pipe 3-3, subsequently into vertical flushing dredging tube 3-6-1, then lead to
It crosses and laterally rinses on dredging tube 3-6-2 that aperture 3-6-3 is with pressure gets, bottom deposition is rushed.When bottom deposition rushed with
Afterwards, the second valve 3-5 rinsed on the first valve 3-2 and vertical flushing dredging tube 3-6-1 on water inlet pipe 3-3 is closed immediately,
Open connecting tube 3-8 on third valve 3-7 and draining sludge pipe 3-4 on the 4th valve 3-9, bottom punching get up deposition by
It laterally rinses dredging tube 3-6-2 and enters vertical flushing dredging tube 3-6-1, then draining sludge pipe is got by high pressure washing pump 3-1
3-4 discharge.Flushing process directly extracts from circulation well 1-4 by valve transfer, flushing water, does not need additionally to fetch water, and operates
Simply, it saves money.
