Abstract

The invention relates to an emergency fast treatment method of port oil dirt waste water from chemical industry, comprising the following steps of: A, oil-water separation treatment; B, air flotation treatment; C, waste water regulation treatment; D, electric oxidation treatment; E, Fenton reaction; F, neutralization reaction; G, electric flocculation reaction; H, coacervation reaction; I, settling treatment; J, sand carbon filter treatment; K, biochemical reaction; and L, film and artificial wetland treatment; and further comprising a step of a microwave active carbon reaction. The microwaveactive carbon reaction is carried out in a microwave active carbon reactor, wherein the microwave active carbon reactor is an active carbon filling tower, and a microwave emitter is arranged outside the body of the active carbon filling tower. Involved devices of the emergency fast treatment method comprise a circulating pump and an emergency storage tank, which are connected together, wherein anunderground water collecting tank in the step A and an electric oxidization tower in the step D are respectively connected with the emergency storage tank. The emergency fast treatment method disclosed by the invention is used for quickly treating the port oil dirt waste water from the chemical industry and has the functions of retaining and improving deep purification and emergency treatment capabilities of a biochemical pool on waste water.

Description

technical field [0001] The invention relates to the technical fields of sewage treatment and environmental protection, in particular to an emergency and rapid treatment method for port oily chemical waste water. Background technique [0002] Port oily organic chemical wastewater has triple hazards of toxicity, environmental pollution and invasion of alien organisms. In the prior art, a port oily organic chemical wastewater treatment method simply applies the biochemical model of domestic wastewater to treat the wastewater, and the discharged water can only meet the third-level discharge standard, that is, the COD of the discharged water<500mg / L, And this wastewater treatment method has no deep purification reuse and emergency treatment functions. The main problems of this port oily organic chemical wastewater treatment method are: [0003] 1. When a large amount of washing water from chemical storage tanks enters the wastewater treatment equipment, the COD of the incomi...
