First, the characteristics of aquaculture wastewater are:It contains a high amount of suspended solids,along with undigested feed,and fish feces.Additionally, it often has excessive nitrite levels.When selecting aquaculture wastewater treatment equipment,we primarily follow a three-step approach:The first step is physical interception.The wastewater first entersa microfilteror a protein skimmer.During this stage,feed particles and fish feces are separated,ensuring…

Wastewater from laundry operations in hotels and hospitals is characterized by high foam content,coloration, and oiliness.We implement a three-stage enhanced treatment process:First is atomization treatment.Wastewater enters the screening system through grates,where fibrous materials are intercepted.The wastewater then flows into the coagulation-air flotation system—the equipment behind me—where specialized chemicals are addedto ensure removal of suspended solids…

The characteristics of this buried wastewater treatment systemIts key feature is that it is buried undergroundFirst and foremost, it is buried undergroundThen it is buried deep into the groundThus occupying no surface areaIts working principle is as followsFirst, wastewater entersAfter entering our equipmentThe initial process unit isan anaerobicanaerobic process unitThis anaerobic process unitutilizes anaerobic bacteriato…

Firstly, there are many types of air flotation machines: vortex air flotation machines, shallow air flotation machines, dissolved air flotation machines, and electrolytic air flotation machines. Today, I’ll use the dissolved air flotation machine behind me as an example to explain its working principle. First, the tank here is a dissolved air tank. The dissolved…

(3) How is domestic sewage treated?Wastewater first passes through a screen well, intercepting suspended solids ≥5mm (e.g., plastic, fiber fragments) to prevent clogging of downstream equipment.It then enters the equalization tank to balance water quality and flow rate, where agitation devices promote grease separation by flotation.Wastewater flows into the anaerobic tank where microorganisms decompose large…
