Embodiment 1

[0051] A method and treatment system for purifying high-residue waste liquid, comprising the following steps,

[0052] Step 1. Collect the high-residual waste liquid (including blood clots, broken tissues, amniotic fluid, meconium, etc.) produced in the obstetrics and gynecology operating room into the waste water collection box. Remove the solid matter contained in the waste water, and then fall into the waste water collection tank. The lower part of the waste water collection tank is in the shape of an inverted cone. A gas distributor connected to an external ozone generating mechanism is arranged inside the inverted cone-shaped part. The ozone flows from the gas distributor. Dispersed in the distribution holes and poured into the waste water collected by the waste water collection tank;

[0053] Step 2, the waste water flowing out from the bottom of the waste water collection tank enters the oxidation pond, and simultaneously adds a composite strong oxidant to the oxidation...

Embodiment 2

[0062] A method and treatment system for purifying high-residue waste liquid, comprising the following steps,

[0063] Step 1. Collect the mixed high-residue waste liquid from the laboratory department (collected by the unified sewage outlet of the laboratory department, including blood samples, urine samples, flushing wastewater, and wastewater containing test reagents) into the wastewater collection tank, and the wastewater first passes through the filter set at the upper end of the wastewater collection tank. Net, filter and remove the solid matter contained in the waste water, and then fall into the waste water collection tank. The lower part of the waste water collection tank is in the shape of an inverted cone, and a gas distributor connected to the external ozone generating mechanism is arranged inside the inverted cone-shaped part. The ozone from the gas Dispersed in the distribution hole of the distributor and poured into the waste water collected in the waste water co...

Embodiment 3

[0072] A method and treatment system for purifying high-residue waste liquid, comprising the following steps,

[0073] Step 1. Collect high-residual waste liquid from the pathology department (collected by the unified sewage outlet of the pathology department, including tissue residues, embedded fragments, flushing wastewater, and wastewater containing fixed reagents) into the wastewater collection tank, and the wastewater is first collected by wastewater The filter net installed at the upper end of the tank filters and removes the solid matter contained in the waste water, and then falls into the waste water collection tank. The lower part of the waste water collection tank is in the shape of an inverted cone, and a gas distribution channel connected to the external ozone generating mechanism is arranged inside the inverted cone. The ozone is diffused from the distribution hole of the gas distributor and poured into the wastewater collected by the wastewater collection tank; ...

Abstract

The invention provides a method for purifying high-residue waste liquid and a treatment system. filtration and collection, oxidation, pH adjustment, microbiological treatment, flocculation, sand and stone filtration, membrane filtration and finally treatment by adding a disinfectant are sequentially carried out, and after treatment, SS is 9 mg/l or below, CODCr is 7 mg/l or below, and BOD5 is 6 mg/l or below. According to the method and the treatment system, harmful and pathogenic microorganisms in the raw wastewater can be inactivated as soon as possible, the risk of disease transmission is reduced, no odor is generated, the purification effect is good, and safety and high efficiency are achieved.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a method and a treatment system for purifying high residual waste liquid. Background technique [0002] The composition of medical wastewater is complex, especially for medical wastewater discharged from high residual waste liquid (such as surgery, obstetrics and gynecology surgery, flushing, laboratory or pathology sample residue), which not only contains a large amount of protein and bacteria, fragmentary biological Organic pollutants such as tissue debris also contain various medicament flushing fluids for flushing. [0003] At present, although there are sewage and wastewater purification methods in the prior art, most of the treatment methods are for the treatment of industrial wastewater. Treatment methods for discharged wastewater. The existing organic wastewater is mostly aimed at the field of livestock slaughtering, which is used to solve organic pollution such as b...
