A set of small-scale integrated anaerobic-anoxic-aerobic wastewater treatment equipment was designed and produced, and the anaerobic-anoxic treatment link adopts vertical folding and the addition of filler, effectively improving the volume utilization rate and the degree of mud-water mixing. Through trial operation, the tank structure is optimized to effectively address the problem of sludge accumulation in the anaerobic area. The equipment has a high degree of integration, is easy to operate and manage, and is suitable for application in rural decentralized sewage treatment.
