Description
Technical Field
The embodiment of the application relates to the field of sewage treatment, in particular to a sewage treatment system.
Background
The existing sewage treatment system generally comprises a regulating tank 1, an anaerobic system 2, a buffer tank 3, an aerobic biochemical system, a sedimentation tank 5, a clean water tank 6 and a sludge tank 7, wherein the anaerobic system 2 is a core part of the sewage treatment system, and the aerobic biochemical system comprises a primary biochemical aeration tank 41 connected with the buffer tank 3 and a secondary biochemical aeration tank 42 connected with the sedimentation tank 5. As shown in fig. 1, it is a technical process flow diagram of the existing sewage treatment system. After entering the adjusting tank 1, the wastewater is divided into a supernatant meeting the standard discharge standard and a second part not meeting the standard discharge standard after sequentially passing through the anaerobic system 2, the buffer tank 3, the aerobic biochemical system and the sedimentation tank 5, wherein the supernatant is discharged after passing through the clean water tank 6, and the second part is collected in the sludge tank 7.
The anaerobic system 2 generally comprises a single anaerobic tank or an anoxic tank and an anaerobic tank which are connected in a multistage manner, an anaerobic bacterial state is generated in the anaerobic tank, and through the time of more than 4-7 days, macromolecular chains in the sewage are broken bonds to open chains to form micromolecular chain groups or molecules, partial gas and the like.
In the sewage treatment system, the first step is to ensure that the anaerobic system 2 normally and effectively works, only then can provide the condition precondition for the normal work of the aerobic bacteria in the subsequent aerobic biochemical system, otherwise, after macromolecular chain materials and other substances which are difficult to degrade in the wastewater enter the aerobic biochemical system, the aerobic bacteria are almost difficult to degrade, so that the whole sewage treatment system is in a paralyzed state. It can be seen that the anaerobic system 2 of the first step is the most critical part of this system.
The anaerobic system 2 which can work stably and is formed by the sewage treatment system generally takes 3-12 months to complete, namely, a long time is needed to complete the starting process of the anaerobic system 2.
As a key system in the sewage treatment system, the anaerobic system 2 is extremely poor in resistance to water impact, resistance to environmental temperature variation, resistance to sewage quality variation, and the like. And once the anaerobic system 2 is delivered to a client for operation, the whole sewage treatment system is easy to crash due to improper operation of the anaerobic system 2, so that the salesperson must go to the site to clean the anaerobic system 2 and restart the anaerobic system 2, which takes a long time.
An anaerobic system 2 is not effective until it is not operated normally, and it is unacceptable as an industrial system that the anaerobic system 2 in a sewage treatment system is repeatedly in an abnormal state. Therefore, in view of such a situation, it is necessary to provide a new technical system to replace the anaerobic system 2 in the existing sewage treatment system.
In the search for new technologies, the electrochemical technology appearing earlier and the membrane technology system appearing later can partially replace the work of an anaerobic system, but have certain limitations, such as long treatment time, limited PH (potential hydrogen) value of sewage, the problem of membrane blockage, the problem of expensive membrane replacement, and the like, and a considerable part of sewage, so that the technologies are difficult to effectively exert.
