Described small-sized Petrified sewage processor, pretreatment pool is made up of plastic grid screen and rustless steel filter frame.
Described small-sized Petrified sewage processor, the coalescence degreaser entrance of removing oil part is connected with delivery pump, and coalescence degreaser outlet is connected with air supporting oil separation equipment；Flocculating agent formulation tank, coagulant preparing tank all have independent dosing pump that medicament joins air supporting oil separation equipment at regular time and quantity；The oil product that coalescence degreaser separates with oil removal, airfloat equipment enters accumulator tank.
Described small-sized Petrified sewage processor, MBR integrated sewage treating apparatus connects by being placed on the delivery pump bottom Buffer Pool；MBR integrated sewage treating apparatus is made up of anaerobic pond, MBR membrane cisterna, equipment pond and the clear water reserviors being connected to one, and in equipment pond, equipment includes roots blower, self priming pump and switch board.
Described small-sized Petrified sewage processor, sludge separating portion is divided and is connected with MBR integrated sewage treating apparatus by sludge pump；The mud of generation is transported to pressure filter by sludge pump, and filter pressing water out returns to Buffer Pool.
Owing to using technical scheme as above, there is advantages that
Small-sized Petrified sewage processor of the present invention: 1, preprocessing part, utilizes plastic grid screen and rustless steel filter frame, separates the major part particulate matter such as foreign material and sand in petrifaction sewage, it is ensured that stable, the longtime running of device；The coalescence degreaser of 2, removing oil part, can isolate oil droplet and the part particle diameter oil droplet less than 10 microns that whole particle diameters in petrifaction sewage are more than 15 microns；The air supporting oil separation equipment of 3, removing oil part gas pressure, flocculant, coagulant common effect under, oil droplet increases buoyancy to the absorption of gas, make oil droplet ascent rate improve nearly thousand times, thus be greatly improved oil-water separation efficiency, make oil content in petrifaction sewage be less than prescription；4, petrifaction sewage enters MBR integrated sewage treating apparatus.In anaerobic zone, carry out being fully contacted with activated sludge and carry out biochemical reaction；Aerobic zone, places membrane module, and activated sludge and larger molecular organics matter are retained, eliminate second pond by film；Therefore activated sludge concentration is greatly improved, and hydraulic detention time (HRT) and sludge retention time (SRT) fully meet Con trolling index, and the material of difficult degradation the most constantly reacts, degrades；The present invention passes through small-sized Petrified sewage processor, had both saved investment, and in turn ensure that Petrified sewage processor safe operation, sewage qualified discharge.
