A large amount of high-salt wastewater of lead-acid batteries will be produced after the lead recovery process (Sun et al., 2017; Yu et al., 2020; Zhang et al., 2016). The content of calcium, magnesium and lead ions in the high-salt wastewater of lead-acid battery is low, and the main components are sodium sulfate and sodium chloride.

With the increase in battery usage and the decommissioning of waste power batteries (WPBs), WPB treatment has become increasingly important. However, there is little knowledge of systems and norms
In this paper, we report a new lead recycling technology from waste lead acid batteries, in which the alkaline solution containing PbO is directly electrolyzed to produce
Under the Universal Waste Regulations, 40 CFR 273, there are permissible treatment activities. The generator may remove the lead-acid batteries from the devices they are powering; discharge them so as to remove the electric charge; remove the electrolytes as long as the batteries are reclosed immediately after removal; or regenerate them.
The lead-acid batteries are the highest consumer of total lead produced worldwide. Whereas, the lead recovered from the recycling of exhausted batteries serves as the secondary source to fulfill the demand of lead for manufacturing the lead-acid batteries (Zhang et al., 2016).During recycling of batteries wastewater is withdrawn by drilling the batteries, which
The obtained results show that the sulfate removal e ciencies were be a potential candidate for the removal of sulfate and lead from industrial wastewater treatment. Then, 200 mL raw spent lead–acid battery wastewater was slowly added into the 500 mL reactor containing 200 mL of calcium oxide CaO with concentration.
The rapid pace of the development of new energy vehicles will lead to a much speedier rate of waste power battery (WPB) generation. Therefore, the disposal of WPBs is becoming a topic attractive to public investors, as well as receiving intensive attention from academics [1,2] nventionally, the primary practice is a lack of specific treatment, with only
As a result of the wide application of lead-acid batteries to be the power supplies for vehicles, their demand has rapidly increased owing to their low cost and high availability. Accordingly, the amount of waste lead-acid batteries has increased to
rate of lead–acid battery exports from China, which declined at a stable rate after 2016. In 2018, the lead–acid battery export volume for China reached 190.23 million, whereas the import volume was only 10.94 million [16, 17]. This high-trade decit is one of the major causes of the relatively low lead-recycling rate in China.
A new, fully customized system is not always required. In many cases, it can be faster and more cost effective to add to or modify a current wastewater treatment system when this is feasible. Because every waste stream is unique to its application, each wastewater treatment solution must be suited to or specifically tailored to the application.
Therefore, finding a cleaner and more cost-efficient Pb recovery and recycling method is critical to the Pb recycling community. This chapter reviews the waste lead-acid

There are four main components in spent lead acid battery: polymeric containers, lead alloy grids, waste acids and pastes. Among them, the pastes mainly comprise lead oxide (∼9%), lead dioxide (∼28%), lead sulfate (∼60%) and a small amount of lead (∼3%) (Zhu et al., 2012a) monly, lead from battery scrap has been smelted in blast furnace, electric furnace,
Recycling lead from wasted lead acid batteries is related to not only the sustainable development of lead-acid battery industry, but also the reduction of the lead pollution to the environment.
The method has been successfully used in industry production. Recycling lead from waste lead-acid batteries has substantial significance in environmental protection and economic growth. Bearing the merits of easy operation and large capacity, pyrometallurgy methods are mostly used for the regeneration of waste lead-acid battery (LABs).
The average concentration of lead in wastewater is about 3–15 mg/L and the pH of wastewater falls in the range of 1.6-2.9 [ 9 ]. If the battery wastewater is not treated well before discharge to environment, lead can contaminate food and water, and be present in nature.
The removal efficiency of lead was increased after using a carbonation step with 68% for quicklime and 69% for slaked lime. The carbonation process not only enhanced the lead removal efficiency in the battery wastewater but also reduced pH to meet requirements of environmental regulations.
