The invention discloses an advanced treatment method for heavy alkylbenzene
sulfonate (HABS) industrial
wastewater, belonging to the technical field of
water treatment and comprising the following steps: regulating the pH value of the HABS industrial
wastewater to be 2-4 firstly, feeding the HABS industrial
wastewater after pH value regulation in a container, and putting at least two polar plates in the container, wherein the two polar plates are respectively connected with the positive and negative poles of a DC
regulated power supply; regulating the current intensity of the DC
regulated power supply to 2-10A, and
processing for 2-10min, wherein the used polar plates are iron polar plates; standing and
settling for 30min, taking supernate, regulating the pH value of the supernate to be 7.5-9.5, pouring a composite
water treatment agent based on the
mass ratio of 1-2g / L, stirring, and standing and
settling for 1h, wherein the composite
water treatment agent is prepared by compounding diatomite with aluminum polychloride,
ferrous sulphate heptahydrate, aluminum
sulfate aluminium sulfate octadecahydrate or polymerized
aluminium ferric sulfate based on the
mass ratio of 3:1-6. the advanced treatment method in the invention lowers COD index, has simple operation and is easy to realize
automatic control, and the generated
sludge can be used as an auxiliary material for
subgrade and brickmaking, and has relative low cost.
