Small and medium-sized town sewage treatment
With the accelerating process of urbanization in China, the number and scale of cities and towns continue to expand, and the water consumption and drainage of cities and towns continue to increase. If the serious water pollution problems caused by the expansion of the number and scale of cities and towns are not effectively dealt with, it will seriously affect people's quality of life and water safety.
Characteristics of municipal sewage water quality in small and medium-sized towns:
(1) The population is small, the water consumption standard is low, and the sewage treatment scale is small.
(2) The coefficient of change is large, the water volume is uneven, and the day and night change is large.
(3) The level of economic development is low, the economic affordability is weak, and there are few applicable technologies to choose from.
(4) There is a serious lack of maintenance and management technicians and operation management experience.
When selecting the municipal sewage treatment process in small and medium-sized towns, it should be considered that the treatment and discharge should "meet the standard", the treatment technology should be "economical and applicable", and the maintenance and management should be "simple and convenient".

2. Technical advantages
The existing engineering practice shows that the Qingda Guohua flat membrane MBR system has the following advantages in urban sewage treatment:
(1) The use of membrane assembly to replace the gravity sedimentation of the traditional activated sludge method to complete the mud-water separation process can greatly improve the sludge concentration of the reactor.
(2) Small footprint, strong impact load, long service life, high degree of automation, excellent and stable water quality, which is more practical in sewage treatment in small and medium-sized towns in the north where water resources are tight.
(3) The inverted A2/O-MBR process has stable and efficient effect on domestic sewage treatment, strong impact load resistance, and the main water quality indicators such as COD, SS, NH4-N, TN, TP, BOD5 and so on meet and exceed the national pollutant discharge standard for urban sewage treatment plants (GB18918-2002).
