Phytoremediation and also use the agricultural/ food wastes to adsorbing or bio-adsorbing heavy metals especially Lead, Cadmium and ...
Some plants are highly tolerant to heavy metals, being indicated as accumulator. There are papers that tolerant sunflower lead.
There are various methods of phytoremediation to remove heavy metals from sewage/ wastewater but they have to be used before sending sewage water to field.
Phytoremediation is one of the most common method for removing heavy metals, phytoremediation using plants as heavy metals accumulator ,
if you asking which phytoremediation method, i think it depend to which plants you wanted to use, is it floating aquatic plants/submerged aquatic plants or another type of aquatic plants.
Is SSB (sewage sludge biochar) capable of replacing phytoremediation to remove heavy metal abundances from sewage sludge!!!
Sewage, if not contaminated with any other industrial effluents , the level of heavy metals are not significant enough. Still, all the aforesaid methods as described are no doubt efficient and might be employed.

Phytoremediation is the most effective way to deal with the heavy metals in sewage sludge irrigated soil. However, sometimes application of certain materials such as humic substances and biochar that can bind the heavy metals in soil by complexing with metals. Therefore, metals became unavailable to plants.
