★Scope of application

This process is suitable for the treatment of high-temperature, high-concentration, high-chroma biodegradable wastewater generated by the food industry.

★Main technical parameters

Influent CODcr≤20000mg/L; water volume≤2000T/D; effluent CODcr removal rate≥95%; BOD removal rate≥99%; NH3-N removal rate≥90%; biogas output rate 0.5m3/kg, COD effluent meets the national sewage discharge standard GB8978-1996

★Technical features

The AO method is the main process flow. The anaerobic part adopts the UASB reactor form, equipped with a high-resistance pulse water distribution system, which effectively flushes and washes the sludge, and ensures that the sludge bed is in a suspended state. The upper part adopts a three-phase separation system to ensure the reflux of sludge, forming a UASB reactor. The aerobic part adopts the contact oxidation method.

★FAQ

Q. What are the common sewage treatment processes?
A. Common sewage treatment processes include activated sludge method (such as A²/O, oxidation ditch, SBR), biofilm method (such as biofilter, biorotor), membrane bioreactor (MBR), etc. These processes mainly use physical, biological and chemical means to remove organic matter, suspended solids, nitrogen and phosphorus and other pollutants in sewage to achieve standard discharge or water resource reuse.

Q. How is the sludge generated during sewage treatment handled?
A. The sludge generated during sewage treatment needs to be concentrated, dehydrated, stabilized (such as anaerobic digestion) and other treatments to reduce the volume and reduce pollution. The treated sludge can be used as a resource, such as fertilizer, incinerated for power generation, or landfilled. Reasonable disposal of sludge is an important part of ensuring that the entire sewage treatment process meets environmental standards.

Q. Does the sewage treatment plant have a bad smell? How to control the odor pollution?
A. Sewage treatment plants may produce bad smells at water inlets, grit chambers, sludge treatment areas and other places. In order to control the odor pollution, deodorization measures such as sealing facilities, negative pressure collection, chemical washing, biological filters or activated carbon adsorption are usually adopted, and the plant area is reasonably laid out and green belts are set up to reduce the impact on the surrounding environment.
