Abstract
The integrated air floating and filtering water treating process includes the following steps: 1. adding flocculant in 10-40 mg/l to raw water to flocculate; 2. mixing with air dissolving water of pressure not lower than 0.3 MPa for 2-3 min for air floating reaction in the air floating area height of 1.5-2.0 m; and 3. filtering at speed of 8-10 m/hr first in active carbon layer of 0.6-0.8 m thickness and then in bioceramic layer of 0.4-0.6 m thickness. The present invention integrates air floating unit, active carbon adsorption unit and bioceramic degradation unit inside one structure to eliminate algae, algal poison and organic pollutant simultaneously. The present invention may be applied in both new and old water works.
Description
(1) technical field
The present invention relates to a kind of water conditioning process, particularly a kind of water conditioning process that is applicable to that algae, algae toxin and organism are removed simultaneously.
(2) background technology
The present water usually algae removal technology of usefulness is the oxychlorination treatment process, and frond can be destroyed in the water in treating processes, discharges the algae toxin, and the healthy of drinking person in serious threat.
(3) summary of the invention
The technical problem to be solved in the present invention is: a kind of efficient algae that removes is provided, simultaneously algae toxin and organism is had the air-float filtration integral water conditioning process of removing ability more by force.
In order to solve the problems of the technologies described above, the present invention adopts following steps: drop into coagulating agent among (1) Xiang Yuanshui, dosage is 10-40mg/L; (2) the little flocculation of former water back is not less than 0.3MPa dissolved air water mixing 2-3 minute with pressure, forms the air supporting reaction, air flotation zone height 1.5-2.0m; (3) filter, filtration velocity is 8-10m/h, and first active carbon layer filters, and active carbon layer thickness is made as 0.6-0.8m, and regrowth haydite layer filters, and the haydite layer thickness is made as 0.4-0.6m.
The invention has the beneficial effects as follows, remove algae by air-dissolving air-float, algae forms little flocs unit in the water, not broken frond, have well and go turbid effect except that algae, and the biological degradation of charcoal absorption and haydite has stronger removal ability to organism and solvability algae toxin, therefore air-float technology, charcoal absorption and biological ceramic particle degradation technique is integrated in the structures, can realize efficiently removing algae, algae toxin and organism simultaneously; In addition,, adopt little flocculation technique, activated filter film technology, form little flocculation-active filter bed floating filter technology, can be used for the transformation and the design of new water factory of old water factory because of this technology does not need flocculation basin.
(4) embodiment
Below three specific embodiments adopt and draw yellow reservoir water as former water, the major equipment of employing has floating filter, establishes contact reacts chamber, air flotation zone and filtrating area in the floating filter.
Specific embodiment one

More than in three kinds of specific embodiments: described dissolved air water is through molten being so incensed that of refluxing of purifying waste water after above three steps; Water distribution system adopts small resistance water wiring system, and the work period is 24h, and is every through a work period, and adopt gas, water backwashing mode to wash once backwash mode: first gas dashes, and backwash rate is 1 5L/sm
2, flushing 1min; Back water dashes, and backwash rate is 15 L/sm
2, flush time is 9min; Coagulating agent can adopt aluminium iron polychloride; Gac adopts the Filtrasorb300D high active granular gac of U.S. Ka Ergang (Cargon) carbon element company Development and Production, this charcoal is high reactivity, a durable gac of selecting for use bituminous coal after selected and tamanori to make, activation treatment through strict control, gac has bigger specific surface area, hole size can adsorb multiple macromole or small molecules organic pollutant in it, product meets U.S. AWWA granular carbon standard B604-96, ANSI/NSF standard 61 and food chemistry product regulation.
The former algae class of floating filter run duration total amount mean value is 2.15 * 10
8Individual/L, go out the algae total amount and the algae clearance is highly stable, go out the algae amount: specific embodiment one is 4.85 * 10
7Individual/L, clearance is: 77%, and specific embodiment two is 2.73 * 10
7Individual/L, clearance is: 87%, and specific embodiment three is 2.12 * 10
7Individual/L, clearance is: 90%.
The effluent quality changing conditions of table 1 Yuan Shui and three kinds of specific embodiments
| Turbidity (NTU) | Colourity (PCU) | Olfact | Oxygen-consumption (mg/L) | UV254 (cm -1) | Chlorophyll a (μ g/L) | |
