AI Technical Summary

Technical Problem

Existing medical wastewater treatment systems suffer from problems such as large footprint, lengthy processes, high operation and maintenance costs, low automation, inaccurate reagent dosing, uneven mixing, and poor system stability. They are particularly difficult to meet the needs of efficient and intensive treatment in small-scale medical institutions and emergency scenarios.

Method used

The integrated medical wastewater treatment system features a compact layout, including a wastewater storage tank, a purification tank, and a purified water storage tank. The purification tank is divided into a sedimentation zone, a first mixing zone, and a second mixing zone by a partition. It is equipped with multi-layer filters and propeller blades driven by a stirring motor. Combined with the precise addition of flocculants and disinfectants and ultraviolet disinfection, it achieves a multi-stage physical-chemical-disinfection process.

Benefits of technology

It enables automated and intensive treatment of medical wastewater, reduces land area and operation and maintenance costs, improves suspended solids removal rate and disinfection effect, adapts to different water quality fluctuations, and is suitable for space-constrained scenarios.

Abstract

This utility model relates to the field of medical wastewater treatment, and more particularly to an integrated medical wastewater treatment system. It includes a wastewater storage tank, a purification tank, and a purified water storage tank. The purification tank is equipped with a first partition and a second partition, which divide the purification tank into three areas: a sedimentation zone, a first stirring zone, and a second stirring zone. The sedimentation zone is equipped with a mounting frame on which several layers of filter screens are horizontally mounted. A first stirring motor is located above the first stirring zone, and the output end of the first stirring motor is connected to a first stirring shaft. First stirring blades are mounted on the first stirring shaft. This system achieves automated and intensive treatment of medical wastewater through a multi-stage physical-chemical-disinfection process, combining high efficiency, reliability, and economy.
