Sewage Treatment 

Sewage treatment may also be referred to as wastewater treatment. However, the latter is a broader term which can also refer to industrial wastewater. For most cities, the sewer system will also carry a proportion of industrial effluent to the sewage treatment plant which has usually received pre-treatment at the factories themselves to reduce the pollutant load. If the sewer system is a combined sewer then it will also carry urban runoff (stormwater) to the sewage treatment plant. Sewage water can travel towards treatment plants via piping and in a flow aided by gravity and pumps. The first part of filtration of sewage typically includes a bar screen to filter solids and large objects which are then collected in dumpsters and disposed of in landfills. Fat and grease is also removed before the primary treatment of sewage.

Hongsen Domestic Sewage treatment Equipment

Hongsen Domestic Sewage treatment Equipment is buried below the surface, the surface above the equipment can be used for greening or other land, there is no need to build houses and heating, heat preservation....


The equipment adopts international advanced treatment process in the sewage treatment plant in China and on the basis of operating experience, combined with our own scientific research and engineering practice, design a kind of can be set up ground of complete sets of organic wastewater treatment plant, removal of BOD5, COD and NH3 - N in one, with technology is stable and reliable performance, good treatment effect, saving investment, automatic operation, maintenance is easy to operate, not covering surface area, no need to build a house, also no need to heating of the heat preservation, etc. Flowers and grass can be planted above the ground without affecting the surrounding environment.


Process Flow Chart




Working Principle

A. The waste water enters the adjustment tank. Due to large changes in the discharge amount and water quality of the waste        water, the adjustment tank is set up to regulate the water quality and water quantity.

B. A/O treatment process is adopted to improve the removal rate of pollutants, which can not only effectively reduce BOD5,
    but also effectively remove phosphorus and ammonia nitrogen.

C. Anaerobic reaction tank is adopted to fully mix the backflow sludge and water under anaerobic conditions. Phosphorous              bacteria release phosphorus and simultaneously absorb low molecular acids in the environment and store in the form of PHB.

D. The secondary biological contact oxidation pond is adopted, in which high dissolved oxygen and excellent biological bacteria         react with organic pollutants, creating the most adaptive environment for the removal of organic pollutants, the oxidation of       ammonia nitrogen and the absorption and removal of phosphorus, and improving the removal efficiency of organic pollutants       and ammonia nitrogen and phosphorus.

E. The radial flow sedimentation tank is mainly used to clarify the effluent from the contact oxidation tank. Therefore,
    the design of the sedimentation tank adopts reasonable design parameters, thus improving the clarifying effect.

F. The amount of sludge produced in this process is very small. After the sludge enters the sludge pond for simple concentration      treatment, it can be cleaned out and disposed out manually every year.


Application Area

The equipment is suitable for use in a residential area, villages, towns and villages, office buildings, shopping malls, hotels, restaurants, nursing homes, organs, schools, units, hospitals, highways, railways, factories, mines, scenic spots such as sewage and similar slaughter, aquatic products processing, food and other small and medium size industrial organic wastewater treatment and reuse.The sewage treated by the equipment meets the international discharge standards.Our company can provide water recycling equipment at the same time according to customer requirements.
