Embodiment 1

[0051] Use the wastewater from electronic parts manufacturing factories with the following water quality as raw water, and use figure 1 The treatment device for wastewater containing organic matter is shown.

[0052]

[0053] COD Cr : 1500~3000mg / L (average 2000mg / L)

[0054] T-N: 30~70mg / L (average 50mg / L)

[0055] T-P: 3.0mg / L (Ca, Mg, K, and other trace metals are added together as nutrients)

[0056] As the anaerobic biological treatment tank 1, a tank with a capacity of 10 L (cylindrical shape of φ16 cm×H60 cm) was used, the hydraulic residence time was 4.8 hours, and the treatment was performed by heating to a temperature of 35°C.

[0057] In the anaerobic biological treatment tank 1, 4L polypropylene cylindrical carrier (φ3mm×5mm) was filled, and 500mL of pellets from the wastewater treatment facility of the beer factory were put into 500mL as seed sludge, and after acclimatization for 2 months, the treated Water is introduced into the aerobic biological treatment...

Abstract

The invention provides a processing device for drained water with organic matters, which can improve the film filter performances of aerobe processing sludge, maintain a high membrane flux and lower the medicine cleaning frequency when an aerobe processing is performed and a membrane separation processing is performed on aerobe processing water after an anaerobe processing is performed on the drained water with organic matters. The device comprises an anaerobe processing groove (1) for performing anaerobe processing on the drained water with organic matters; an aerobe processing groove (2) for performing aerobe processing on the anaerobe processing water flowed out from the anaerobe processing groove (1); a membrane separation device (5) for performing solid-liquid separation on the aerobe processing water from the aerobe processing groove (2). The device is characterized in that a biological fixing bed (4) is equipped inside the aerobe processing groove (2).

Description

technical field [0001] The invention relates to a treatment device for organic matter-containing drainage, which performs aerobic biological treatment after anaerobic biological treatment and performs membrane separation treatment on aerobic biologically treated water, in particular to a treatment device for organic matter-containing drainage The treatment device, as the aerobic biological treatment tank after the anaerobic biological treatment tank, adopts the membrane separation activated sludge type aerobic biological treatment tank, which improves the membrane filterability of the aerobic biological treatment sludge and The water permeation (flux) of the membrane is improved. Background technique [0002] Conventionally, as a treatment method for organic-matter-containing wastewater, a method is known in which anaerobic biological treatment is performed on organic-matter-containing wastewater, followed by aerobic biological treatment and solid-liquid separation of aerobi...
