1. Device overview.
According to the unique water properties of hospital sewage, the development and production of equipment specifically for hospital sewage treatment, the equipment advanced technology, simple management, after treatment water quality testing can meet the standard.
Name: Hospital integrated sewage treatment equipment.
Treatment process: AO process.A2O process.MBR membrane process.
Scope of application: hospital wastewater purification treatment.
Hospital integrated sewage treatment equipment.
Second, the process introduction.
The equipment adopts the international advanced biological treatment technology, which integrates the removal of BOD5.COD.NH3-N, and has the advantages of stable and reliable technical performance, good processing effect, less investment, less land occupation, and convenient maintenance. It can also be equipped with reclaimed water reuse equipment according to customer requirements.
3. How to use.
1. Can treat comprehensive wastewater and similar organic sewage in small and medium-sized hospital systems;
2. The full set of devices is simple to construct, easy to operate, all mechanical equipment are automatically controlled, and all devices can be set below the surface;
3. Easy management and maintenance, the equipment is equipped with a fully automatic control system. The service life is more than 30 years.
Fourth, outstanding characteristics.
1. The hospital integrated sewage treatment equipment can be buried below the surface, and the surface above the equipment can be used as greening or other land, without the need to build houses and heating. It can also be placed on the ground.
2. The secondary biological contact oxidation treatment process adopts push-flow biological contact oxidation, and its treatment effect is better than that of complete mixing or secondary tandem complete mixed biological contact oxidation tank. It is smaller than the activated sludge tank, has strong adaptability to water quality, good impact load resistance, stable water quality, and no sludge expansion.
The new elastic three-dimensional filler is adopted in the pool, which has a large specific surface area and the microorganism is easy to hang the film and delay. Under the same organic load, the organic matter removal rate is high, which can improve the solubility of oxygen in the air in water.
3. The biochemical tank adopts biological contact oxidation method, the filler volume load is relatively low, the microorganism is in the stage of self-oxidation, and the mud production is small, only three months (90 days) (inhaled or dehydrated into mud cake with a manure truck).
4. In addition to the conventional high-altitude exhaust, the buried domestic sewage treatment equipment is also equipped with soil deodorization measures.
5. The whole equipment processing system is equipped with automatic electrical control system and equipment fault alarm system, which is safe and reliable in operation. In general, it does not require special management, only timely maintenance and maintenance of equipment.
5. The internal control system facilities of the equipment.
1.2 sets of sewage lifting pump, 1 with 1 preparation. Automatic operation according to the adjustment cell level switch, low level stop work, high level normal operation, 6-8 hours automatic switching.
2. 1 outlet pump, 1 backwash pump. According to the automatic operation of the membrane reaction cell level control switch, the high level is operating normally, the sewage lift pump stops running, and the low level self-priming pump stops running. Under normal circumstances, it is turned on for 8 minutes and stopped for 2 minutes. After the outlet pump stops working, the backwash pump starts and the backwash membrane is backwashed.
3. 2 blowers, 1, 1 blower. Under normal circumstances, the fan runs continuously. In order to prolong the service life, the two are used alternately and work for 6-8 hours to switch automatically.
4. Control a sludge return pump according to the sludge volume time.
5. A mixed liquid return pump, always open.
6. Electrical control equipment is equipped with automatic alarm, which can not only be automatically controlled, but also manually controlled. Remote control can also be achieved according to customer requirements.
