There are many domestic sewage treatment facilities in towns and villages, which should be decided according to the actual situation in your area. The following principles should be grasped when selecting the corresponding sewage treatment equipment: First, not only the capital investment of disposable equipment should be considered, but also the future operation and maintenance cost of the equipment should be considered emphatically, and the factors such as its own economic situation, population density, industrial distribution and development should be weighed. Second, it is necessary to consider that the effluent quality of the equipment meets the standard and have a long-term awareness of improvement. For example, now the country may meet the X-class emission standard. What if the equipment fails to meet the new standard after the country upgrades the emission standard in the future? Scrapping and reinvesting? Third, we should choose advanced sewage treatment equipment, and generally choose less technologies and equipment that are backward or on the verge of elimination. Fourthly, the efficiency, long-term, stability and unattended automation of sewage treatment equipment should be considered. Five: Before choosing the domestic sewage treatment equipment in villages and towns, we should inquire more, search more, and learn more about it on the Internet or in reality.
At present, the technologies and equipment of domestic sewage treatment in villages and towns mainly include: traditional septic tanks, biogas fermentation tanks, constructed wetlands, integrated sewage treatment equipment, buried sewage treatment equipment and so on. Among them, the integrated "membrane method" sewage treatment equipment has the highest degree of automation and the most stable and best effluent quality, which can reach and exceed the first-class A standard of the highest national standard. It is the first choice equipment for urban domestic sewage treatment at present. Integrated membrane wastewater treatment equipment is divided into traditional membrane bioreactor system MBR equipment and new intelligent membrane biological wastewater treatment system IMBRS equipment. The former is the foundation of the latter, and the latter is the upgrade of the former.
The choice of sewage treatment equipment should be combined with its own situation, local conditions, taking into account its own present situation and future development.
