Integrated Sewage Treatment Equipment to Purify Water Quality Standard Discharge

The principle of

By adding a certain amount of suspended carrier to the reactor, the biomass and biological species in the reactor were improved, so as to improve the treatment efficiency of the reactor.Since the packing density is close to water, when aerating, it is in a completely mixed state with water, and the environment for microbial growth is gas, liquid and solid.The impact and shear action of the carrier in the water makes the air bubbles finer and increases the utilization rate of oxygen.In addition, each carrier has different biological species inside and outside, some anaerobic bacteria or facultative bacteria grow inside, and the outside is a good bacteria, so each carrier is a micro-reactor, so that the nitrification reaction and denitrification reaction exist at the same time, thus improving the treatment effect.

Due to the high concentration of organic matter in sewage, the microorganisms are in anoxic state, at this point, the microorganisms are facultative microorganisms, so the a-level anaerobic pool not only has A certain organic matter removal function, to reduce the subsequent aerobic pool.Aerobic microorganisms decompose organic matter into CO2 and H2O.Autotrophic bacteria (nitrifying bacteria) use inorganic carbon generated by organic decomposition or CO2 in the air as A nutrient source to convert nh3-n in sewage into no-2-n and no-3-n. The effluent of o-level pool flows back to a-level anaerobic pool to provide electron acceptor for a-level anaerobic pool. Nitrogen pollution is eventually eliminated through denitrification.The intermediate sputum has the effect of DO and nitric acid oxygen, so it cannot improve the removal effect of nitrogen and phosphorus.The second sewage flows into the subsequent o-level aerobic tank through the a-level anaerobic tank, which is mainly composed of aerobic microorganisms and self-oxygen-type bacteria (nitrifying bacteria).

The device with city tap water or customer local groundwater as raw water, the scale inhibition, softening, filtration, dosing desalination, such as processing technology, the main equipment including series of filters, dosing pump, reverse osmosis equipment, ozone and uv detector, water purification effect is good, and durable, can save costs, have important significance to the development of enterprises.Without water purification equipment, people would boil the water and drink it.The advantage of using reverse osmosis is that the phase change will not occur in the process of water production.And the water use efficiency is high, the energy consumption is less, saves the environmental protection, conforms to the modern technology the green environmental protection characteristic, so this has been widely used.The site water reuse equipment system is more suitable for the following situations: small and medium town domestic sewage and industrial waste water from factories and mining enterprises, especially in places with large intermittent discharge and flow variation.Places requiring higher water quality, such as scenic areas, lakes and harbors.
