Description

technical field

[0001] The invention relates to a domestic sewage purification system, in particular to a miniature domestic sewage deep purification system. Background technique

[0002] The miniature domestic sewage treatment system has broad application and development prospects due to its advantages of simple installation, broad-spectrum adaptation, and no need for sewage pipelines. However, the system design currently used in the domestic market has the following main problems:

[0003] 1. Most of the designs are designed and manufactured for domestic sewage to meet the discharge standards, while my country's requirements for domestic sewage to meet the discharge standards are still relatively low, and most areas do not limit the content of phosphorus and nitrogen, so the effluent of most systems cannot be To meet the requirements of wastewater recycling, these designs are already facing the situation of elimination in today's increasingly scarce water resources.
