The Research On Producing Intermediate Water Of Bath Water By Compound SBR Process

Irreplaceable water can be renewable in nature.If water properly treated, it can be used to achieve a virtuous circle of water in the natural world. Building water systems is that the amount of sewage coming back to life as miscellaneous district for the construction of water or green washing water supply system after treated properly. If intermediate water process system installed, it can reduce water and other water supply, save precious fresh water resources,and ease the water shortage situation. It can reduce displacement and the burden on urban drainage system and water pollution to the environment. So, it has obvious social benefits and environmental benefits. Bathing wastewater which is high quality miscellaneous drainage is a major source of intermediate water. The trial is aim to discuss the acclimation process and operating conditions through mud from the sewage plant species collected, trained and tamed adding suspended filler with transforming ratio domesticated by compound SBR. SBR process combined with suspension filler to make microorganism on the filler and wastewater extensive and frequent contact. Fill in the process of cutting and dispersed bubble flow, which enabled the uniform gas and improve the utilization of oxygen. Raw sewage processing capability has been greatly enhanced. Compound SBR proved a solid state law suspended and activated sludge wastewater microbes can be well used to meet the water quality. Microorganisms has activity such as the appearance of large numbers of microorganisms indicative big bell insects, condensation worms; Bathing water has little impact on microorganisms in the system The system for BOD₅, COD_cr, NH₄⁺-N, SS has higher removal and removal rate is faste to effluent. And pH value is between 6.5 to 9.0.From the sensory indicators, color is less than 20 degree, the effluent is clear , pleasing and no foul . Those indexes are compatible with China's water quality standards.So the water fits to return; And semi-automatic control equipment and various on-line testing equipment is used.It is found that DO, pH and ORP have distinctive features while treating domestic sewage and wastewater low concentration of bath by compound SBR. Control indicators curve has goodreproducibility.It can control reaction process achieve the highly effective and conserves energy according to the changes of DO, pH and ORP.
