Combined efficient biological treatment of domestic wastewater characteristics: no special management and slag cycle length using the apparatus of sewage treatment, sewage treatment facilities do not need someone to manage the long-term cost savings for the user management. This process uses no sludge biological treatment technology, microbial conversion of the organic compounds and hazardous air pollutants (nitrogen oxides), heat and water, for a long period slag geographic sewage treatment equipment manufacturers, under normal circumstances the main Facilities Qingtao three to five years only once, reducing the clean-up costs. Sewage treatment equipment with the characteristics, there does not occupy a lot of public space slaughtered sewage treatment equipment, but also to the long buried in the ground below the low use. The device itself is digital, it does not require too much manpower and material resources in the use of this device above, which greatly facilitates the use of the process. There is the effect of sewage treatment itself is very good, so that has contaminated materials can clean out the appropriate place in the inflow. The most important is the quality of the equipment is very good, long-term work can not fault occurs, the term used is very long.
