Embodiment Construction

[0033] The treatment device provided by the invention mainly includes:

[0034] Multi-functional regulating pool, hydraulic retention time ≥ 4 hours, stainless steel plane grille is installed at the water inlet end of the regulating pool, and the grid gap is 30mm; a submersible sewage pump is installed behind the regulating pool, which is used to transport the anaerobic and anoxic biological iron-carbon reaction pool for inward electrolysis. Water, the internal electrolysis anoxic anoxic bio-iron-coke reaction pool of the present invention is divided into an internal electrolysis anaerobic bio-iron-coke reaction pool and an internal electrolysis anoxic bio-iron-coke reaction pool.

[0035] Both the internal electrolytic anaerobic biological iron-carbon reaction tank and the internal electrolytic anoxic biological iron-carbon reaction tank are hung with Φ120 and L1200 combined elastic fillers. The iron filler at the bottom of the pool is calculated at 20-30kg / kg COD, and the bio...

Abstract

The invention discloses a device for treating organic oil-containing wastewater. The device mainly comprises a multifunctional adjusting tank, a deodorization device, an internal electrolysis anaerobic/anoxic biological iron carbon reaction tank, a flexible biological membrane contact oxidation tank, an air blower room, a sedimentation tank, an artificial wetland and an ecological landscape pond. According to the method and device disclosed by the invention, micro-electrolysis is used as a pretreatment technology, and the organics and nitrogen and phosphorus pollutants in the oil-containing wastewater and the animal and plant oil in the wastewater are removed according to the combined action on organic pollutants by the microorganisms in suspension and attachment states and in combination with the physical and chemical adsorption sedimentation-percolation process and the plant absorption and conversion process. The method disclosed by the invention combines the advantages of the technologies such as iron carbon filtration and biological iron method, A2/O technology, artificial wetland, artificial floating island and the like, realizes strong pretreatment ability and small floor area, and has the characteristics of large water treatment quantity, strong purification ability, good landscape effect, low operation cost, ecological safety, stable water output and strong pollution load resistance and hydraulic load impact resistance.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a treatment device for organic oily waste water. [0002] The invention also relates to a method for treating organic grease-containing wastewater by using the device. Background technique [0003] In addition to organic matter, oily wastewater also contains non-biodegradable oil. If it is discharged directly, the oil will form an oil film on the water surface, hindering oxygen transmission and threatening the survival of aquatic animals and plants. The main processing methods currently used are physical, chemical and biological methods. Physical methods mainly include mechanical oil separation, air flotation, and gravity sedimentation, while chemical methods mainly use electrolysis and flocculation. The dilution, aggregation or migration in different environments may cause secondary pollution, so it is not popular. The biological method is favored because of its lo...
