small size domestic sewage treatment plant

Small size domestic sewage treatment plant      1.General Introduction  Simultaneous A/O biofilm reactor biodegradation technology nis adopted by NEST Small-Scaled Water Purification Equipment. Therein, high efficient modified filler was explored and utilized to realize the class 1 A standards(GB18918-2002)of “discharge Standard of Pollutant for Municipal Sewage Treatment Plant”(besides TP). Noticeably, Model NEST-600(Buried), with the operation power of 17 Watts, can in favor of 1-2family wastewater treatment service; Moreover, 2-3 families cervices can be offered by Model NEST-900 (Buried), which handles under 35 watts of operation power.   Mechanical and power equipment was not available inside the chamber. Barrier-free point in the life cycle and the service life can last for more than 20 years. In adition, external draught fan is established in order to maintain more convenient. Besides, advantage like unattended operation was obvious and the inorganic sludge treatment produced from the NEST can be cleared by the professional maintenance department for annual regulart services. Thus the equipment is really suitable for the current rural wastedwater treatment.   Application: Countryside, agritourism, Villa sanitary sewage, garden landscape water treatment, etc. Treatment capacity 0.5-10m3/day   Effluent standard: realize the class 1 A standards(GB18918-2002)of “discharge Standard of Pollutant for Municipal Sewage Treatment Plant”(besides TP).   Technology: adopt multi-stage “anaerobic+aerobiotic” technology, and use high efficient modified filler. Without sludge backflow or mixed liquid back flow. Model 1 Model 2 Installation 1   Installation 2
