With the growth of economy and population, more and more attention has been paid to the pollution of nature. On the basis of
summarizing the operating experience of domestic and foreign domestic sewage treatment facilities and combining with our own scientific research achievements and engineering practice, we have designed a complete set of buried organic wastewater treatment equipment. This equipment adopts advanced technology and manufacturing technology in China and abroad, and produces the sewage treatment equipment with glass fiber, carbon steel and non-steel as the main material. Its main purpose is to make domestic sewage and similar industrial organic wastewater meet the discharge standard required by users after being treated by the equipment.
The equipment is mainly used for domestic sewage treatment in residential districts (including villas), high standard hotels, hospitals, comprehensive office buildings and various public buildings. The effluent quality treated by the equipment meets the national discharge standard. The whole set of equipment can be buried underground, so it is also called "geographical domestic sewage treatment equipment".
The company's buried domestic sewage treatment equipment adopts international advanced biological treatment technology, integrates removal of BOD5, COD and NH3-N, with the advantages of stable and reliable technical performance, good treatment effect, less investment, less land occupation and convenient maintenance, etc. Our company can also provide reclaimed water reuse equipment according to requirements of customers.
Application Method of Integrated Sewage Treatment Equipment
1. It is able to treat integrated comprehensive wastewater of living system and the similar organic wastewater;
2. The complete set of equipment is simple in construction and easy to operate. All mechanical equipment is automatically
controlled, and all the equipment can be set below the surface of the earth;
3. It is easy to manage and maintain. The equipment is equipped with automatic control system;
Scope of Application
1. Hotels, restaurants, sanitariums and hospitals;
2. Residential districts, villages and markets and towns;
3. Stations, airports, harbor, wharves and ships;
4. Plants, mines, troops, tourist spots and scenic areas;
5. Various industrial organic waste water similar to domestic sewage;
A2/O Process
SMC sewage treatment tank adopts A2/O process, which ensures the removal effect of COD, ammonia nitrogen, total nitrogen and also strengthens the removal effect of phosphorus.SMC sewage treatment tank adopts biological process, where microorganisms mainly grow on spherical filler media, which can achieve the separation of hydraulic retention time and sludge retention time, and help to enrich the specialized functional microorganisms which have a long generation time and a good treatment effect, and the biological is microbial aggregation with certain thickness, and compared with activated sludge method, biofilm method is more resistant to shock load and the operation of the equipment is more stable. SMC sewage treatment tank adopts the design concept of low volumetric loading, and the hydraulic retention time is more than 24 hours, which helps to increase the microbial self-oxidizing ability, and improves the quality of the effluent while reducing the production of residual sludge, and reduces the cost of sludge treatment and the cost of construction of sludge tanks. SMC sewage treatment tank is simple and unmanned operation, the use of Internet of Things technology can realize remote mobile management to save operation and maintenance labor costs.
A²O Process Schematic Diagram
(1) Anaerobic, anoxic, and aerobic, the combination of three different environmental conditions and microbial communities are capable of simultaneously removing organic matter and nitrogen and phosphorus.
(2) In the process of simultaneous deoxygenation, phosphorus removal, and organic matter removal, this process flow is the simplest, and the total hydraulic retention time is also less than other similar processes.
(3) Under the alternating environmental of anaerobic, anoxic and aerobic, filamentous bacteria do not reproduce in large numbers, and the SVI is generally less than 100, so sludge expansion does not occur.
(4) The phosphorus content in sludge is high, generally above 2.5%.
