Description

A kind of strong oxidizing reaction and flocculation filtration all-in-one
Technical field
The utility model belongs to the environmental protection equipment field, is that the useful strong oxidative function of a kind of sewage disposal apparatus flocculation filtration function of holding concurrently is the equipment of one specifically.
Background technology
In the sewage disposal, during particularly some industrial sewages are handled, usually run into the water quality of some difficult hardly-biodegradables, the common method of handling these water quality at present is:
1. advanced oxidation processes comprises ozone oxidation, Fenton reagent oxidation, hydrogen peroxide oxidation etc., with hardly degraded organic substance direct oxidation degraded in the waste water;
2. micro-electrolysis method, as iron-carbon micro-electrolysis etc., the electronics that utilizes little electrolysis to produce is opened more organic groups, resolves into small-molecule substance, is conducive to follow-up biochemical treatment;
3. distillation method is distilled the salt mother liquor etc. of containing of high density, and reducing has inhibiting inorganic salts etc. to biochemical bacterium in the waste water, is convenient to follow-up biochemical treatment.
The factor of integrated operation expense and cost of investment each side adopts advanced oxidation processes at present mostly, and maximum with Fenton reagent oxidation style employing wherein especially.
Present Fenton reagent oxidation style, mainly contain two types, a kind of is traditional Fenton oxidation style, another kind is to be the fluid bed Fenton oxidation style of representative with Taiwan Mercury, the great advantage that fluid bed Fenton oxidation style is compared the conventional oxidation method is to save medicament, sludge yield is few, is therefore also more and more used.
But also there is following weak point at present in fluid bed Fenton oxidation style: the one, and xln is in fluidized state in the sewage in order to make, waste water need keep than higher flow velocity, and in order to take into account the certain reaction time that guarantees, generally adopt the quantity of reflux way that increases waste water to improve flow velocity at present, so just increased the consumption of the energy; Simultaneously, because size, the density of crystal are inconsistent in the water, flow velocity is big, will flow away by the less xln of the less density of some particle, flow velocity is little, will some particle greater density bigger xln precipitation and fluidisation is not got up, therefore, whole fluid mapper process is difficult to control, can't reach best fluidized state, makes wastewater treatment efficiency not good.The 2nd, though fluid bed Fenton oxidation style is more many than traditional Fenton process mud decrement, but there are many valency iron mud to produce, the follow-up technology that flocculating settling and filtration also will be arranged has increased investment and working cost and floor space.The 3rd, in fluid bed, the solid phase content of crystal can be too high also unstable, influence fully contacting of sewage and crystal, feasiblely reacts insufficient.The 4th, because water distribution is inhomogeneous, influenced reaction effect, reduced effluent quality.
The utility model content
The utility model is wayward at energy consumption height, fluidized state that existing fluid bed Fenton oxidative treatment sewage exists, water distribution is inhomogeneous and deficiency such as subsequent treatment process complexity, a kind of strong oxidizing reaction and flocculation filtration all-in-one are provided, and energy consumption is little, water distribution is more even and have multiple function.
The utility model is by the following technical solutions:
A kind of strong oxidizing reaction and flocculation filtration all-in-one comprise reacting tank body, and the bottom in the reacting tank body is provided with tapered bottom, and water distributor is equipped with in the bottom, and top is provided with inclined tube, and the middle part is provided with filter bed and the self-circulation sand filtering device of band filtrate.
