Complex heavy-metal waste water emergency quick treatment method

Abstract

The invention relates to a complex heavy-metal waste water emergency quick treatment method, comprising the following steps of: filtering by a sand filter; mixing by a high-speed pump; carrying out an ultraviolet catalyzing ozone reaction; carrying a microwave catalyzing active carbon reaction; carrying micro-electrolytic reaction; circulating waste water; carrying out a Fenton reaction; carryingout electric flocculation on an aluminum electrode plate; and pressing and filtering sludge. Waster water in a circulating slot is pumped into an iron carbon fluidized bed by a fluidizing pump to be circularly treated; an air compressor is connected with the iron carbon fluidized bed and prevents a filler in the iron carbon fluidized bed from blocking; and 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. The complex heavy-metal waste water emergency quick treatment method disclosed by the invention is used for treating the complex heavy-metal waste water, associated devices are simple, easy, quick, can meet an emergency, and can update and convert, no various chemical raw materials are fed, and various complex heavy-metal waste water with unknown elements can be quickly treated as long as the current magnitude is regulated, and thus the heavy metal in the waste water and chemical oxygen demand can immediately reach the standard and are discharged.

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 complex heavy metal wastewater. Background technique [0002] At present, the environment, resources, and population have become the three major problems facing the world. The deterioration of the global environment is increasing day by day, which is posing a serious threat to the survival and development of human society. With the disorderly development of electronics, electroplating, circuit boards, and home appliance dismantling industries, heavy metal pollution is becoming more and more serious, and sudden heavy metal pollution incidents are increasing year by year, which has caused great harm to my country's soil, rivers, agricultural production and people's health. The government has listed heavy metal pollution as an urgent problem to be solved. [0003] Heavy metal pollution has the charac...

Problems solved by technology

[0012] The technical problem to be solved by the present invention is: to overcome the defects of complex automatic control system adopted in the heavy metal wastewater treatment technology of the prior art, resulting in large investment, large land occupation, non-movability, and high operating cost, and to provide an emergency and rapid treatment of complex heavy metal wastewater method, this emergency and rapid treatment method for complex heavy metal wastewater is embodied by corresponding equipment. The corresponding equipment has three functions: simple and fast, emergency and upgrade conversion. It does not need to invest in various chemical raw materials, and only needs to adjust the current size Rapidly treat heavy metal wastewater with various complex and unknown components, so that the heavy metals and chemical oxygen demand in the wastewater can be discharged up to the standard immediately
