Problems solved by technology

However, the treatment efficiency is limited, and only one branch can only be used to treat the wastewater on one branch line.
And the effect in the process of backwashing water is not good, causing the internal parts used for filtering to be easily blocked, requiring frequent cleaning, increasing the cost in use, and bringing great inconvenience to the work

Abstract

The invention relates to the field of electro-nickel wastewater treatment, and particularly discloses an electro-nickel wastewater treatment method, and backwashing water equipment used by the same. The electro-nickel wastewater treatment method comprises an electro-nickel wastewater collection pool, a raw water tank, a sand filter tank, a UF system, an RO system, a reaction tank, a plate-and-frame filter press, a drying oven and a reuse water RO system which are connected in sequence. The nickel electroplating wastewater is treated by the treatment method, the operation is simple, and the operation cost is low. Water resources are fully utilized in the treatment process, and nickel resources are not prone to being wasted. And the reaction tank is fully utilized in the treatment process, so that the electric nickel concentrated liquid of a manufacturer can be treated along with the reaction tank, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a wastewater treatment method, in particular to an electro-nickel wastewater treatment method and backwash water equipment used therein, and belongs to the field of electro-nickel wastewater treatment. Background technique [0002] In the field of wastewater treatment, nickel-containing wastewater is a toxic wastewater with high concentration and refractory degradation. Heavy metals in wastewater cannot be biodegraded and accumulate in organisms, causing chronic poisoning. At present, the methods for treating nickel-containing wastewater mainly include chemical treatment, adsorption, ion exchange and membrane separation technology. The single use of chemical method not only occupies a large area and is difficult to meet the standard stably; the adsorbent used in the adsorption method is expensive and will cause secondary pollution; the operation process of the ion exchange method is more complicated, and it will The impact re...
