The invention relates to
sewage treatment equipment, in particular to a power-free highly effective dispersion type domestic
sewage treatment integrated equipment designed for aiming at municipal housing plots, guesthouses, resorts,
nursing homes, airports and rural areas. The equipment is composed of a
sedimentation tank, two or more anaerobic reactors connected in series, and a
sludge digestionreactor, wherein
polypropylene elastic three-dimensional filling material is respectively arranged at the center parts of the anaerobic reactors and the
sludge digestion reactor, and anaerobe grows on the elastic three-dimensional filling material in a way of
biological membrane. The treatment equipment of the invention has the advantages: firstly, the treatment equipment has higher flexibility and adaptability, the one-time investment is low, the amount of
sludge is small, and the management is convenient; secondly, the
polypropylene elastic three-dimensional filling material is arranged inside through adopting the anaerobic
contact process, the specific surface area is large, and the
biomass is large; thirdly, the
organic matter can be fully degraded; fourthly, the security performance is good; fifthly, the structure is simple, the complete set of the treatment equipment can realize promotion, and the treatment equipment is in favor of popularization; the treatment equipment is applicable to the dispersion type domestic
sewage treatment in the residential districts, the guesthouses, the resorts, the
nursing homes, the industrial enterprises and the troops and the rural areas.
