Project Name: Yuanjiang Yuan Dispersed Wastewater Treatment Project in Changping Town, Dongguan City
Engineering application industry: suitable for environmental protection engineering applications such as municipal sewage treatment, centralized sewage treatment in towns and rural areas, and restoration and treatment of river polluted water bodies
Owner: Changping Town Water Engineering Operation Center
Project address: The project is located in Yuanjiangyuan Community, Changping Town, Dongguan City
Land area: The project covers an area of approximately 1380m2
Project scale: Daily sewage treatment capacity of 5000m3/d
Construction and operation mode: adopting EPC+O mode
Key technologies:
1. Equipped with mature decentralized sewage treatment technology, through the combination process of "pretreatment+AO activated sludge method+secondary sedimentation tank+flocculation+high-density sedimentation", the effluent effect is stable, the impact load resistance is strong, and it still has high operational stability under C/N changes and high ammonia nitrogen. The decentralized sewage treatment technology has flexible site selection, compact design, small footprint, and short construction period. It can also be combined with fixed biofilm technology to fill efficient denitrification fillers in the biochemical system, enhance synchronous nitrification and denitrification effects, and improve the metabolic activity, diversity, and selectivity of functional bacteria.
2. Chemical phosphorus removal from the effluent of the biochemical tank is simple to operate, with significant and stable phosphorus removal effects.
3. Adopting high-density sedimentation, fast start-up, small footprint, easy operation, not affected by changes in flow rate and pollutant load, high sedimentation efficiency, and good effluent quality; The sludge concentration is high, and the generated sludge can be directly dehydrated without the need for a sludge concentration system.
