Zero discharge method for wastewater from vanadium extraction factory

Abstract

The invention relates to the technical field of wastewater treatment and discloses a zero discharge method for wastewater from a vanadium extraction factory. The method comprises steps as follows: pavement of a header pipe: mounting of a wastewater collection header pipe along rivers nearby a vanadium extraction door, a river intake pump room, a steel rolling bridge, a steel making bridge, an ironmaking bridge and a domestic sewage treatment station. By means of the zero discharge method for the wastewater from the vanadium extraction factory, the wastewater collection header pipe along riversnearby the vanadium extraction door, the river intake pump room, the steel rolling bridge, the steel making bridge, the ironmaking bridge and the domestic sewage treatment station is mounted, six chemical oil discharging and settling ponds are added, water quality treatment facilities and pipe network systems are perfected step by step, and meanwhile, a special steel zero discharge water treatment system and a wastewater comprehensive treatment system are arranged, so that when the method is implemented, good facilities are provided for support, the wastewater treatment capability is increased, no obvious production wastewater is discharged to the rivers, and wastewater collection, treatment and balance use processes by the factory are stable and controllable.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a method for zero discharge of waste water in a vanadium extraction plant area. Background technique [0002] Vanadium is a silver-white metal with a high melting point. It is often called a refractory metal together with niobium, tantalum, tungsten and molybdenum. It is malleable, hard, non-magnetic, and has the ability to withstand hydrochloric acid and sulfuric acid. A large amount of wastewater will be generated in the process, and a large amount of wastewater will also be generated inside the vanadium extraction plant area. If the wastewater is directly discharged into Hanoi, it will not only seriously pollute the environment, but also have a certain fixed impact on human health. [0003] The current vanadium extraction plant area does not have a perfect treatment method for wastewater. Not only is there obvious wastewater discharged into Hanoi in the plant are...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a zero-discharge method of waste water in the vanadium extraction plant area, which has the advantages of no obvious production waste water entering the river, and the collection, treatment and balanced use of waste water are stable and controlled, and solve the current problems. The wastewater treatment method in the vanadium extraction plant area is not perfect. Not only is there obvious wastewater discharged into Hanoi in the plant area, but the process of wastewater treatment, collection and balance is not perfect enough, and the problem of vanadium extraction wastewater cannot be handled well.
