[Kumbahan domestik] Penggunaan mesin lipatan skru perlindungan alam sekitar Dawei dalam kumbahan domestik
2023-01-14
Dalam kehidupan, semua orang akan tertanya-tanya ke mana perginya kumbahan domestik dari cucian harian sayur-sayuran, tangan dan cadar? Adakah ia terus dilepaskan ke sungai? Malah, kumbahan domestik ini akan mengalir ke sungai selepas rawatan profesional oleh loji kumbahan domestik, atau digunakan semula. Jadi bagaimanakah kumbahan domestik menjadi bersih dan mencapai standard pelepasan?
Kumbahan domestik kami dikumpul oleh rangkaian paip utama dan cawangan kumbahan perbandaran, dan kemudian secara seragam memasuki loji rawatan kumbahan domestik.
Prosedur pertama rawatan kumbahan domestik - skrin kasar. Skrin kasar Perlindungan Alam Sekitar Dawei akan menyekat jumlah besar sisa pepejal di dalam kumbahan.
Seterusnya, kumbahan dipam melalui skrin halus, dan mesin skrin halus Perlindungan Alam Sekitar Dawei juga boleh digunakan, jadi sisa pepejal kecil ditapis.

The sewage will flow into the next process - aeration grit chamber. As the name implies, sand setting is to allow large particles of impurities such as sand particles to settle down. Then, the organic matter wrapped on the sand surface is separated by aeration.
The fourth procedure is the cultivation base of microorganisms, which depend on the dirt in the sewage for survival. At the same time, these microorganisms also need stable oxygen to maintain their life.
Further down is the secondary sedimentation tank. At this time, the sludge will settle and the settled sludge will be sent to the sludge treatment system. The sludge can be thickened, conditioned and dewatered through the spiral sludge dehydrator of Dawei Environmental Protection. The dewatered sludge can be transported outside for harmless treatment. At this time, the water is much cleaner.
Customer industry: domestic sewage
Nature of sludge: raw sludge
Equipment model: two screw type sludge dehydrators DW352, full-automatic dosing device 3000L

Then there is the active sand filter. The water flow inside the filter passes through the quartz sand filter material layer, and the pollutant content in the water will be greatly reduced.
Then the water flows into the denitrification filter to remove the total nitrogen and phosphorus in the suspended solids.
Finally, the water flows to the ultraviolet disinfection canal to eliminate pathogens and microorganisms in the water.
The tailwater can be directly discharged into the river after reaching the standard. But sometimes the water source is activated to improve the water quality. Finally, an ecological wetland system will be added, and the treated sewage can be reused to wash roads, use as fountains, water greening, fire fighting, etc.
Kumbahan domestik kami beransur-ansur menjadi bersih selepas proses yang rumit. Setelah memahami proses ini, kami merayu kepada semua orang: untuk melindungi alam sekitar, kita harus bermula dari diri kita sendiri, menjimatkan air, mengurangkan pencemaran, dan mencipta langit biru!
