An overview of the
The ministry of ecology and environment, together with the ministry of housing and urban-rural development (hereinafter referred to as "the two departments"), will launch the 2018 special action on the improvement and environmental protection of black and smelly water bodies in hospitals in early may, covering 36 key cities (municipalities directly under the central government, provincial capitals and cities under separate planning) and other prefecture-level cities across the country.
This special operation, to the satisfaction of the masses as the primary standard, with the hospital black smelly water treatment reference inspector, assigned by, patrol, questioning, special inspector "five steps" experience, a comprehensive understanding of black smelly water treatment progress and existing problems, and urge to speed up the swallow the urban environmental infrastructure construction, fundamentally solve the problem of black smelly water body.
This project is implemented in weifang step by step, using the hospital sewage treatment equipment developed and produced by our factory. The equipment of our company adopts the international advanced biological treatment technology, which can remove BOD5, COD and nh3-n in one. Our company can also provide water reuse equipment according to customer's requirement.
1. Hospital sewage treatment equipment is buried below the ground, and the surface above the equipment can be used as green or other land, without the need of building houses, heating and insulation.
2. The treatment process of secondary biological contact oxidation adopts the push-flow biological contact oxidation, and its treatment effect is better than that of the complete mixed biological contact oxidation tank or the two-stage tandem complete mixed biological contact oxidation tank. Compared with activated sludge tank, the volume is smaller, the adaptability to water quality is strong, the impact load resistance is good, the effluent water quality is stable, will not produce sludge expansion. New elastic stereoscopic packing is adopted in the pool, with large specific surface area, and microorganisms are easy to hang the film and remove the film. Under the same load condition of organic matter, the removal rate of organic matter is high, and the solubility of oxygen in air can be improved in water.
3. The biochemical pool adopts the biological contact oxidation method. The volume load of the filler is relatively low, and the microorganism is in the stage of its own oxidation.
4. The deodorization method of the integrated living sewage treatment equipment in this hospital adopts the routine high-altitude exhaust and the soil deodorization measures.
5. The whole equipment processing system is equipped with automatic electrical control system and equipment fault alarm system. It is safe and reliable in operation.
