The existing battery waste treatment process is mainly to adjust the PH value, and the coagulation sediment effluent is directly discharged after filtration or adsorption, but the influent water quality fluctuates greatly, and the treatment system does not have enough buffer capacity to ensure the stability of the effluent. The existing waste liquid treatment is mainly based on ordinary resin adsorption or reverse osmosis. The technical disadvantage of ordinary resin adsorption is that: when heavy metal wastewater enters the resin adsorption tower when the coagula

Embodiment 1
[0029] A new energy vehicle battery waste liquid treatment process, the specific steps are as follows:
[0030] Step 1: Normal operation of water production, the water inlet valve and the water production valve are opened at the same time, and the two switching valves are closed to make the two resin towers run in series. When one of them enters the non-water production state, the corresponding switching valve is opened;
[0031] Step 2, the first backwash: the discharge pump of the discharge tank is turned on, the resin tower provides backwash water and the switching valve between the two resin towers is opened, the backwash water inlet valve is opened at the beginning of the process, and the backwash drainage pneumatic valve is completed at the end of the process Start to drain water until the resin backwash valve is opened, and the backwash time is 5-15 minutes;
[0032] Step 3, the first air wash: the blower is turned on at the beginning of the air wash, the air intake pne...

Abstract
The invention discloses a waste liquor treatment flow of a new energy automobile battery. The flow specifically comprises the following steps: S1, normal operation to generate water; S2, backwashing for the first time; S3, gas washing for the first time; S4, acid regeneration; S5, thick discharge of acid; S6, alkali regeneration; S7, thick discharge of alkali; S8, backwashing for the second time;S9, gas washing for the second time; S10, conventional well-flushing; S11, refluxing; and S12, normal operation to output water. Heavy metals are recovered from battery waste liquor, and heavy metalscan be also concentrated, extracted and recovered from a hydrometallurgical solution. Industrial useful metals can be recovered from electroplating eluting liquor, metal pollutants in a treatment roomcan be removed, trace heavy meals are removed selectively from metal surface modified plant waste water under the condition of very high calcium ion concentration, and heavy metals can be extracted selectively under the circumstance of coordination agents such as nitrogen compounds, polybasic carboxylic acid and phosphate.
Description
technical field [0001] The invention relates to the field of waste liquid treatment, in particular to a waste liquid treatment process for new energy vehicle batteries. Background technique [0002] With the increase in the number of automobiles and the increase in the severity of automobile pollution, people have accelerated the research process of new energy vehicles. New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. [0003] Batteries are an important part of new energy vehicles, providing power for new energy vehicles. The battery will be discarded after use, but the waste liquid of the waste battery needs to be treated. The battery waste liquid contains a large amount of heavy me...
