The invention discloses a forward permeable membrane
cleaning agent and a method for applying the same, and belongs to the technical field of
water treatment agents. The forward permeable membrane
cleaning agent comprises 0.5-2.0mg / L of
silver nano-
particle suspension liquid which is dispersed in 0.025%-0.05% of
sodium dodecyl
benzene sulfonate. The forward permeable membrane
cleaning agent and the method have the advantages that the forward permeable membrane cleaning agent is wide in application range and can be used as a forward permeable membrane online reverse cleaning agent instead of absorbing liquid for forward permeable membrane bioreactors; a cleaning process is applicable to forward permeable membranes made of various materials, trace
silver nano-particles and partial silver ions released by the
silver nano-particles can be transmitted through membrane pores along with reverse washing water under a reverse cleaning effect of the water, accordingly, sterilization effects can be realized for organisms on
contamination layers deposited on the surfaces of the membranes, the organisms on the surfaces of the membranes can be inactivated, adsorption effects of the organisms on the surfaces of the membranes can be deteriorated, the organic biological
contamination layers on the surfaces of the forward permeable membranes can be effectively removed, and the forward permeable membrane cleaning agent is free of damage to the forward permeable membranes and can be reused; the forward permeable membrane cleaning agent and the method are scientific and reasonable in design and have an important significance on solving the difficult problem of
contamination of existing forward permeable membranes and expanding application of the silver nano-particles and the forward permeable membranes.
