Each several part principle of work of the present invention is seen shown in Figure 2.
Regulatory region (equalizing tank zone): water inlet is generally neutrality, for satisfying the required sour environment of follow-up advanced oxidation, through adding sulfuric acid or hydrochloric acid, will intake about pH regulator to 2.5～3.
Oxidation zone (oxidation pond zone): come the organic pollutant in the water inlet is carried out oxygenolysis through adding Fenton reagent (oxygenant is a ydrogen peroxide 50, and catalyzer is a ferrous sulfate).Fenton reagent can produce the extremely strong hydroxyl radical free radical of oxidisability, can make most organism complete oxidation generation water and carbonic acid gas in the water, and the small portion oxidation operation is to be simple and easy to biochemical small organic molecule, thereby reaches the purpose that reduces COD.Key of the present invention is to adopt effective ways that oxygenant residual in the water (ydrogen peroxide 50) is removed, and makes the COD value drop to very low numerical range.In the oxidation zone final stage, add alkali (sodium hydroxide, calcium hydroxide) the pH value is transferred to neutrality.
Coagulation disengaging zone (coagulation separation cell zone): in the water of peroxidation, contain part small organic molecule and some iron mud.Add flocculation agent and coagulant aids in the coagulation district, make the tiny solid that forms in the water behind the stirring reaction, from water, separate through deposition, filtration or air supporting.Effluent quality improves.
Concrete operations step of the present invention is: specifically open total water intaking valve 1, observe total flooding velocity under meter 2, through the sour start and stop that add pump of on-line monitoring instrument control, after water quality met the requirements of the pH value, water got into oxidation pond 4 through pipe-line transportation according to former water pH.The unlatching oxygenant adds pump and catalyzer adds pump, adds medicament to oxidation pond 4, opens the oxidation pond whisking appliance simultaneously, promotes reaction to carry out.After reaction was accomplished, middle water flowed into aeration tank 5, opened alkali and added pump, and water body pH is adjusted back to neutral.Flow into coagulation separation cell 6 again, open coagulant aids and add pump, under the effect of coagulant aids, make that the subtitle substance flocculation can settled flco for big volume in the water.Then water is carried out mud, water sepn through deposition, filtration or air supporting.Open outlet valve 12 and go out water pump 13, water outlet is delivered to made land used.If mud reaches a certain amount of in the separation cell, open mud valve 15 and sludge pump 14, then can realize spoil disposal.When clearing up, open emptying valve, Chi Zhongshui is emptied in maintenance with to device.
The above; Only be the embodiment that the present invention is directed to the inventive method; The foregoing description is not that the present invention is done any restriction; Every according to the present invention the given scope of technical scheme and any simple modification, change and equivalent structure that above embodiment did changed, all still belong to the protection domain of technical scheme of the present invention.
