Package Sewage Treatment System – Waste Water Plant

The application of package sewage treatment system:

The package sewage treatment system is used for domestic sewage (mixture waste water from household toilets, , sinks , showers and washing machines), hospital waste water ,industrial effluent, the contaminated surface water and ground water.

Treatment process:

The effluents flows into screen for big particles separating after collected by drain channel, then enters into adjusting tank for homogeneity and equant. A level controller is setted in the adjusting tank, who can deliver sign to CPU. The effluents were sent to A biological contact oxidation pond for acidification hydrolyzing and nitration-denitration in the order of reduce the concentration of organic matters and wiping and remove part ammonia nitrogen. After that enter into O biological contact oxidation pond for aerobiotic biochemical reaction. O biological pond is divided into two stages, and most organic contaminants are degraded by biological oxidation and adsorption. And now the effluents auto-flows to the second sediment pond for solid-liquid seperation. After that the upper clear liquid flows into disinfecting tank for bacterica remove by adding chlorinate chemicals. The disinfected clear liquid can be used for flower watering , toilet flushing, or discharge directly. The sundries held back by the screen are collected by the truck and delivered to wasteyard regularly. The sludge in the second sedimentation tank , some reflux to A biological reaction tank and some are took off by the truck. The upper liquids of the sludge tank refluxs to adjusting tank for retreatment.
