The invention provides a hydrophilic biological carrier for
wastewater treatment. The hydrophilic biological carrier comprises base materials, hydrophilic functional materials and auxiliary materials, the base materials include high-density
polyethylene, the hydrophilic functional materials include iron
trioxide,
coke and
slag powder or
polyvinyl alcohol, and the auxiliary materials include talcum
powder. The density of the hydrophilic biological carrier for
wastewater treatment is 0.93-1.05g / cm<3>, the biological carrier is rough in surface, large in specific surface area, short in membrane hanging time and high in
impact resistance, can prevent microbial membranes attached to the outer surface of the carrier from falling off due to friction between the carriers in water, contact angles of
sewage and the carrier are reduced, the hydrophilicity of the carrier is improved, so that microorganisms are more easily attached to the carrier, the biological carrier is provided with enhanced components of biological
enzyme, the catalytic action of the biological
enzyme is facilitated, the enhanced components are high in
biological activity and fast in
metabolism, the
decomposition capacity of
contamination in the water can be remarkably improved, the biological carrier contains
ultraviolet-resistant components, the service life of the biological carrier is longer than 30 years, and replacement and maintenance are omitted.
