Embodiment

Below in conjunction with accompanying drawing and instance the present invention is done further description.

As shown in Figure 1; Waste water feeds water collecting basin and is promoted to equalizing tank via lift pump, and equalizing tank is promoted to iron carbon tower via impeller pump, and the outlet of iron carbon tower connects the neutralization precipitation pond via waste pipe; Neutralization precipitation is provided with tube settler in the pond; The neutralization precipitation pond connects the concurrent oxidation and aquoiysis pond via waste pipe, and the concurrent oxidation and aquoiysis pond connects the MBR pond via waste pipe, and the MBR pond connects monitor well via suction pump; Described tube settler all is connected plate-and-frame filter press via spiral pump with the MBR pond, and plate-and-frame filter press is communicated with water collecting basin via water pipe.

Described water collecting basin comprises grille well and oil trap; Grille well is connected oil trap via water pump with valve pipe; Described concurrent oxidation and aquoiysis pond and MBR pond all are equipped with micro-hole aerator and reinforced polyvinyl chloridepipe aerating system, and described sludge treating system setting is equipped with plate-and-frame filter press.

1. water collecting basin: flow into water collecting basin after on-site waste water compiles, advance before the water collecting basin, remove the large particulate matter in the waste water, with anti-clogging plug water pump and valve pipe earlier through grille well.Oil trap is to remove the grease that floats on the surface.Be promoted to equalizing tank by lift pump then.

2. equalizing tank: equalizing tank function homogeneous, equal amounts.In equalizing tank, adding dilute sulphuric acid regulates pH value and is promoted to iron carbon tower by corrosion resisting centrifugal pump to 2-3..

3. iron carbon tower: mix, the PH2-3 Rubber Industrial Wastewater is transported to iron carbon tower.Filler is made up of plane iron flower (being the waste material that lathe turning is got off) and grain active carbon in the iron carbon tower.Wherein the plane iron flower is 5: 1 (w/w) with the input ratio of grain active carbon. drop into successively in the tower, make the two distribution even as far as possible.Waste water stopped 12 hours in iron carbon tower, noted plane iron flower oxidation situation in the tower.Often add the plane iron flower to guarantee its iron carbon rational proportion.

4. neutralization precipitation pond: add Ca (OH) in the water outlet of iron carbon tower ₂Carry out the PH adjustment.First lattice add Ca (OH) automatically through PH on-line monitoring appearance in neutralization tank ₂, control PH:7.5-8.5, adopt mechanical stirring to mix.Add flocculation agent PAM in second lattice, make the small-particle coacervating large particle, accelerate sludge settling.

Tube settler precipitates suspended substance (SS).Tube settler bottom mud is pressed in the plate-and-frame filter press with spiral pump and dewaters.Inclined tube is answered periodic flushing in the tube settler, prevents that top suspended substance from accumulating too much its function that influences.

5. concurrent oxidation and aquoiysis pond: because Rubber Industrial Wastewater B/C ratio, so waste water makes through the concurrent oxidation and aquoiysis pond that the macromolecular organic pollutant of difficult degradation is hydrolyzed to micromolecular organic pollutant in the waste water, thereby improves the biodegradability of waste water.Semi soft packing, aerating system 1 cover, (KBB micro-hole aerator, UPVC pipe) are installed, intermittent aeration, control dissolved oxygen≤0.5mg/l in the concurrent oxidation and aquoiysis pond.
