Characteristics of process technology
It is an efficient combination of membrane separation technology and biological treatment method. Its origin is the use of membrane separation The technology replaces the secondary sedimentation tank in the activated sludge process for solid-liquid separation. This process not only effectively achieves the purpose of mud-water separation, but also has advantages that are incomparable with traditional processes for three-stage sewage treatment:
It can efficiently separate solid-liquid and its separation effect is much better than that of traditional sedimentation tank effluent. The water quality is good, the suspended solids and turbidity of the effluent are close to zero, and it can be directly reused, realizing the recycling of sewage.
The high-efficiency interception effect of the membrane enables the microorganisms to be completely trapped in the bioreactor, achieving flexible and stable complete separation operation control of the reactor hydraulic retention time (r) and sludge age (r).
Since r combines the aeration tank and secondary sedimentation tank of traditional sewage treatment into one and replaces all the process facilities of tertiary treatment, it can significantly reduce the floor space and save civil construction investment.
The interception and propagation system for nitrifying bacteria has high nitrification efficiency.
Because the mud age can be very long, the degradation efficiency of refractory organic matter is greatly improved.
When the reactor operates under high volume load, low sludge load, and long sludge age, the remaining sludge production is extremely low. Since the sludge age can be infinitely long, zero sludge discharge can be theoretically achieved.
Overall design of sewage treatment station
The basic principles for the layout of sewage treatment stations are: functional zoning, reasonable treatment processes, and unobstructed structures. The structures should be arranged as compactly as possible to reduce the floor space and fully consider the proximity. , Coordination and connection of long-term projects are both beneficial to production and convenient for operation and management. Integrated equipment includes flocculation reaction tank, r tank, disinfection tank, sludge tank, etc.
Membrane module selection
The membrane module of this project uses hollow fiber membranes that have been widely used in various sewage (waste) water treatment projects.
