The invention provides a
residual chlorine controllable environment-friendly medical
wastewater deep disinfection and sterilization device. The device comprises a pretreatment module, a
solid-liquid separation module, a
wastewater disinfection module, a
wastewater sterilization module, a
residual chlorine monitoring module and a
residual chlorine adding module, wherein the pretreatment module, the
solid-liquid separation module, the wastewater disinfection module and the wastewater sterilization module are connected in sequence; the residual
chlorine monitoring module and the residual
chlorine adding module are arranged at the wastewater disinfection module; a residual
chlorine adding module and a residual chlorine monitoring module are arranged at the wastewater disinfection module for two purposes, firstly, the residual chlorine content in the
water body is detected through the residual chlorine monitoring module, and when the residual chlorine content in wastewater is detected to exceed the standard, the neutralizing
medicine can be added into the disinfection box so that the purpose of controlling residual chlorine is achieved, the
automation degree is high, and the detection result is accurate, secondly, a plurality of hollow
crank arms are arranged on the unfolding type spraying disc, the spraying area of the
sodium hypochlorite solution in the disinfection box can be completed by unfolding or combining the hollow
crank arms, the mixing uniformity of the
sodium hypochlorite solution and the
water body can be increased, the disinfection efficiency is improved, and disinfection dead angles are avoided.
