Integrated sewage treatment equipment for daily life
Product Introduction:
Integrated sewage treatment equipment is a device that integrates a primary sedimentation tank, I and II stage contact oxidation tanks, a secondary sedimentation tank, and a sludge tank, and performs air blowing aeration in the I and II stage contact oxidation tanks to effectively combine the contact oxidation method and activated sludge method, while possessing the advantages of both and overcoming their disadvantages, thereby further improving the level of sewage treatment.
Introduction to integrated sewage treatment equipment:
1. The sewage treatment consists of secondary tanks, made of steel structure and buried shallowly. The steel structure pool adopts the domestically pioneered interpenetrating network anti-corrosion coating for corrosion prevention. It is an interpenetrating polymer formed by the interpenetrating of a rubber network and a plastic network. It is resistant to acid, alkali, salt, gasoline, kerosene, aging, abrasion, and rust. After applying the coating, the anti-corrosion life of the equipment can generally reach more than 12 years.
2. The AO biological treatment process in sewage treatment equipment adopts a push flow biological contact oxidation tank, which has better treatment than fully mixed or two-stage series fully mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, strong adaptability to water quality, good impact resistance, stable effluent quality, and will not cause sludge expansion. At the same time, a new type of elastic three-dimensional packing material was used in the biological contact oxidation tank, which has a large actual specific surface area and is convenient for microbial biofilm formation and detachment. Under the same organic load conditions, it has a higher removal rate of organic matter than other packing materials and can improve the solubility of oxygen in water.
3. Due to the use of a biological contact oxidation tank in the AO biological treatment process, the volume load of the packing is relatively low, and the microorganisms are in the self oxidation stage, resulting in less sludge production. In addition, the moisture content of the sludge produced by the biological contact oxidation tank is much lower than that of the sludge produced by the activated sludge tank. Therefore, the amount of sludge generated by sewage treatment equipment is relatively small, and generally only needs to be discharged once every 90 days.
4. In addition to conventional measures such as vibration isolation pads and silencers, the integrated sewage treatment equipment also incorporates new sound-absorbing materials on the inner wall of the blower room, reducing the noise level during operation to below 50 decibels and minimizing the impact on the surrounding environment.
5. The fiberglass integrated sewage treatment equipment is equipped with a fully automatic electrical control system and equipment damage alarm system, ensuring good equipment reliability.
6. The integrated sewage treatment equipment can be buried underground, and the surface can be used as green or square land, so the equipment does not occupy the surface area, does not require building, and does not require heating and insulation.
This project adopts the biofilm method: anaerobic aerobic (A/0) treatment process. A/O, also known as anaerobic+aerobic biological contact oxidation, is a mature biological treatment process that has the advantages of high volumetric load, fast biodegradation rate, small footprint, low infrastructure investment and operating costs. It can replace the ordinary activated sludge method used in urban sewage treatment and is particularly suitable for the treatment of medium and high concentration industrial wastewater, with low investment, small footprint, and high treatment efficiency. This process adopts a combination of biological contact oxidation and precipitation, and is mature and reliable. Sludge is precipitated in the equipment, and a portion of the sludge is further oxidized and decomposed due to the action of dissolved oxygen, while another portion is lifted into the sedimentation tank. The system sludge only needs to be regularly pumped in the sedimentation tank. The working program of the main control equipment such as the wind turbine and submersible sewage pump in the system is input into the PLC machine to achieve automatic operation, reduce the workload of operation, and minimize unnecessary human damage.
