Wastewater treatment equipment for washing processes
Wastewater discharged during the laundry industry’s production process contains a large number of pollutants. Laundry wastewater primarily comprises washing wastewater, rinsing wastewater, and spin‑drying wastewater. Each type exhibits distinct characteristics: washing wastewater contains surfactants, sodium tripolyphosphate, carboxymethyl cellulose, oil‑based contaminants, particulate matter, and various microorganisms; it appears turbid, has a pH of 6.5–7.5, and features a high suspended solids content. Phosphate discharge into water bodies can lead to eutrophication, while surfactants, once introduced, may cause toxicity and mortality in aquatic organisms and increase the solubility of certain micropollutants. Rinsing wastewater is voluminous, produces slight foam, contains fewer suspended solids and lower COD levels, and is relatively clear. Spin‑drying wastewater is minimal in volume, with water quality slightly better than that of rinsing wastewater.

Acid Pickling and Phosphating Wastewater Treatment Equipment
Acid pickling and phosphating is a pre‑treatment process used prior to metal machining, designed to remove oil and rust, perform surface conditioning, and apply a phosphate conversion coating. The wastewater generated during this process originates from degreasing and phosphating operations in metal finishing. It primarily contains emulsified oils, degreasers, lubricants, surfactants, suspended solids, phosphate ions, as well as organic and inorganic contaminants such as acids and alkalis. The combined effluent exhibits high levels of organic matter, along with substantial amounts of phosphorus, oils, and suspended solids.

Meat processing wastewater treatment equipment
Meat-processing wastewater is industrial effluent generated during meat processing. It typically comprises two main components—slaughtering and meat processing—and may also include ancillary facilities that produce by-products such as edible oils, gelatin, and soap. The wastewater originates primarily from operations including slaughter, dehairing, carcass splitting, evisceration, and cleaning, as well as from rinsing workshop equipment and floors. It contains blood, hair, fats, meat fragments, and various impurities, resulting in poor water quality: BOD5 of 300–2,200 mg/L, suspended solids of 600–3,000 mg/L, oil and grease concentrations of 200–1,000 mg/L, and coliform counts ranging from 2.38 × 10^6 to 2.38 × 10^7 CFU/L, with substantial volumes. Approximately 10 tons of wastewater are produced for every ton of live livestock slaughtered. Wastewater treatment should employ a segregated‑flow approach, separately collecting and treating streams containing oil and grease, those without oil but containing fecal matter, and other types, before combining them for secondary biochemical treatment. Common methods include the activated sludge process, biofilters, rotating biological contactors, and combined anaerobic–oxidation pond systems.

The food industry is highly complex, encompassing production processes such as sugar manufacturing, brewing, meat processing, and dairy processing. The wastewater generated from these operations contains organic matter, exhibits strong biochemical oxygen demand, and carries substantial suspended solids. Wastewater from animal‑based food processing further includes animal excreta, blood, hides and fur, and fats, and may also harbor pathogenic microorganisms; consequently, it has a very high oxygen demand and is far more polluting than wastewater from plant‑based food processing.

Dissolved air flotation equipment
An air flotation machine is a device that uses small or microbubbles to bring suspended impurities to the water’s surface. When water contains fine particulates with densities close to that of water, which are difficult to settle or rise naturally, this air flotation system can be employed.

Wastewater Treatment Equipment for Dental Hospitals
The LQ‑type dental aesthetic clinic wastewater treatment system employs physical or chemical processes to treat effluent (as per customer requirements), eliminating the need for chemical additives and preventing excessive chlorine discharge. It also avoids additional operating costs. The core process comprises disinfection followed by filtration and adsorption. Disinfection works by disrupting and oxidizing microbial enzyme systems and nucleic acids, thereby rapidly inactivating bacteria and viruses. The filtration‑adsorption unit can effectively remove chemical reagents, radioactive isotopes, BOD, COD, large particulate matter, and other conventional pollutants from laboratory wastewater. Under standard operating conditions, the complete system has a continuous service life of 30,000 hours.

The sodium hypochlorite dosing system primarily comprises a chemical storage tank and a dosing metering pump. If the storage tank is not equipped with an agitator, liquid chemical agents can be directly fed into the system. The equipment requires no complex control signals; once the desired dosage is manually set, it can operate continuously and automatically.

The primary mechanism of sodium hypochlorite disinfection involves its hydrolysis to generate hypochlorous acid, which further decomposes to produce nascent oxygen [O]. The highly oxidizing power of nascent oxygen denatures proteins and other biomolecules on bacterial cells and viruses, thereby killing pathogenic microorganisms. Furthermore, during the process of bactericidal and virucidal action, hypochlorous acid not only targets cell walls and viral envelopes but, owing to its small molecular size and lack of charge, can also penetrate into microbial (viral) cells, where it reacts oxidatively with cellular proteins, nucleic acids, enzymes, and other organic macromolecules, leading to the inactivation of pathogenic microorganisms. Additionally, the chloride ions released by hypochlorous acid can markedly alter the osmotic pressure of bacterial and viral cells, causing them to lose viability and ultimately die.

Hospital wastewater treatment equipment
Hospital wastewater is similar in quality to conventional domestic sewage, but it differs in that it contains large quantities of pathogenic microorganisms, parasite eggs, and various viruses—such as Ascaris eggs, hepatitis viruses, Mycobacterium tuberculosis, Shigella, and radioactive substances. Therefore, this wastewater must undergo rigorous disinfection to eliminate pathogenic agents and prevent harm to the environment.
