Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example and describe in detail as follows:
Seeing Fig. 1, the present invention includes following technological process,
1) waste water processed through biochemistry pool enters reaction tank, adds medicament, carries out adsorption treatment；
2) entering tubular membrane filter through intermediate pool again, filtrate discharges, and concentrated solution is back to intermediate pool；
3) in intermediate pool, mud is after filter pressing, and filtrate is back to biochemistry pool, and mud cake is transported outward.
Early stage through biochemical treatment waste water enter reaction tank, through interpolation medicament, absorption water in little molecule pollutant,
Small particle, COD etc., form the insoluble matter that bulky grain suspends, be separated from the water process, reach the purpose of purification of water quality,
Described interpolation medicament is coagulant (aluminium polychlorid or poly-ferric chloride), (PAM or formaldehyde are double for macromolecule organic adsorbent
Cyanamide), one or more in activated carbon granule and powder, Calx；Subsequently into intermediate pool, waste water enters pipe by pump
Formula film device filters, and tubular membrane filtered solution discharges after reaching discharge standard, and condensed water is back to intermediate pool, and intermediate pool is dirty
Mud periodically outer row, uses pressure filter filter pressing, and filter press filtrate is back to above biochemistry pool and processes further.
The present invention uses tubular membrane filtering technique to replace traditional sedimentation, and separation accuracy is higher, and mud-water separation is more complete,
All useless dissolubility pollutants in removing water, COD clearance is higher, and effluent quality is more stable；The tubular membrane that the present invention uses
Runner width, crossflow velocity is fast (2.5～5m/s), and anti-pollution ability is strong, and thickened sludge concentration is high, can reach more than 1%.
Described tubular membrane filter is ultrafilter membrane or microporous filtration, and the membrane material used is PVDF or PE or PS, membrane aperture
In 0.01～0.5 μm, it has intensity height, the feature of length in service life, generally uses the life-span more than 5 years.
In the present embodiment, described reaction tank includes first order reaction pond and the secondary response pond of series connection, adds in first order reaction pond
High-efficient decolorizing flocculant, active ingredient is formaldehyde dicyandiamide, adds aluminium polychlorid or PAM in secondary response pond, described
In tubular ultra-filtration membrane cross-flow filtration device, membrane tube water flow inside speed is: 3～5m/s, the hole retaining micropore of described micro-filtration membrane
Footpath is 0.03 micron, and for making reaction tank fully react, two reaction tank mixings time are 15～20 minutes.
The present invention use medicament absorption combine with membrane separation technique, utilize coagulant and adsorbent to reduce COD and colourity,
