Sewage treatment is a process of purifying sewage to meet the water quality requirement of discharging the sewage into a certain water body or reusing the sewage. The sewage treatment plant collects the urban sewage for centralized treatment, the purification of the sewage is mainly completed through a biochemical system, and the sewage is finally discharged after reaching the discharge standard.
at present, a biochemical pool in a sewage treatment plant generally adopts a reinforced concrete pool body structure, in order to ensure that the biochemical pool can safely run for a long time, the wall of the reinforced concrete pool must reach enough thickness, generally 300mm ~ 400mm, and enough reinforcing steel bars are matched to achieve the strength of the biochemical pool during normal running.
The biochemical pond of reinforced concrete structure has many and complicated processes in the work process, needs a large amount of templates, and has large on-site workload and long construction period. Meanwhile, the sewage treatment plant adopts a gravity flow mode in the sewage treatment process, so that the elevation of a structure is strictly controlled in order to ensure smooth water flow and ensure the normal operation of the function of the biochemical pool, however, the construction precision of the reinforced concrete structure is not high, the condition that the elevation of a water outlet is higher than the operation water level possibly exists, the water flow is not smooth, and the sewage treatment plant cannot normally operate.
the reinforced concrete structure biochemical pool is heavy in self weight, uneven settlement of a foundation is easily caused, a pool body cracks and seriously inclines, the use of a building is influenced, and the safety is endangered. Once the pool body is unevenly settled, the foundation needs to be reinforced at high cost.
The sewage in the biochemical pool with the reinforced concrete structure contains a plurality of small inorganic particles, and the inorganic particles can continuously wash the pool wall in long-time operation, so that the concrete on the surface layer is peeled off, the sewage permeates into the wall body, the corrosion of the reinforcing steel bars in the wall body is accelerated, the corrosion volume of the reinforcing steel bars can expand, the peeling of the concrete is aggravated, a vicious circle is formed, and the service life of the biochemical pool is shortened.
Old sewage treatment plants can only be scrapped and dismantled after the service life is over. The cost of demolition is high, but the actual recyclable materials are not much, and the overall recycling value is low.
