[Sampah larut lesapan] Penggunaan Penyusun Siput Perlindungan Alam Sekitar Dawei di Loji Rawatan Air Sisa
2023-01-14
Dalam tahun-tahun kebelakangan ini, klasifikasi sampah merupakan topik yang sangat popular dibincangkan oleh semua orang, dan klasifikasi sampah adalah kondusif untuk pemulihan dan penggunaan semula sumber dalam tempoh kemudian. Bagaimanapun, dalam proses kitar semula di loji rawatan sampah, rawatan kumbahan loji rawatan sampah tidak boleh diabaikan.
The sewage from the garbage treatment plant is mainly the garbage leachate. Let's briefly introduce: What is the garbage leachate? Landfill leachate refers to a kind of high concentration organic wastewater formed by the waste itself in the landfill site, rain and snow water accumulated in the landfill site and some other water, deducting the saturated water holding capacity of waste and overburden, and experiencing the waste layer and overburden. The composition of landfill leachate is quite complex, and it is difficult to make it meet the discharge standard by only one method. Therefore, in order to achieve the discharge standard of landfill leachate, different process methods need to be combined. Due to the high suspended solids and good biodegradability of the sewage in the garbage treatment plant, the current sewage treatment method in the garbage treatment plant is generally biochemical treatment.
The sewage treatment method of the garbage treatment plant is usually the contact oxidation method. It mainly includes: grid, primary sedimentation tank, contact oxidation tank, secondary sedimentation tank, disinfection tank and sludge tank.
The sewage from the waste treatment plant will first be intercepted by the grid with relatively large suspended solids. Then enter the primary sedimentation tank to remove some impurities in the water. The primary sedimentation tank is usually a vertical flow sedimentation tank, and the settled sludge can be pumped to the sludge tank by the sludge pump. The water from the primary sedimentation tank will enter the contact oxidation tank for biochemical treatment. The amount of excess sludge after biochemical consumption will not be too much. However, due to different materials from the garbage plant, the quality of waste water from the garbage plant will be different. Specific treatment should be carried out according to the situation of waste water.
Customer industry: waste water from waste treatment plant
Nature of sludge: treated sludge
Equipment model: screw folding machine DW-301, dosing device DWP-2-500
Selepas mengetahui proses rawatan am air sisa di loji rawatan sampah, masih penting untuk memilih mesin yang akan digunakan semasa memilih enapcemar yang ditinggalkan di loji rawatan sampah. Kumbahan loji rawatan sampah berbeza daripada industri lain. Disebabkan oleh pengeluaran enapcemar yang terhad dan keperluan untuk mengurangkan kos pengangkutan, penyahhidrat enapcemar jenis skru Perlindungan Alam Sekitar Dawei boleh dipilih pada masa ini. Berbanding dengan jenis dehidrator enap cemar yang lain, ia mempunyai ciri kuasa kecil, penggunaan kuasa yang rendah dan keluasan lantai yang kecil, dan lebih sesuai untuk loji rawatan sampah untuk merawat enap cemar di bahagian belakang.
