Problems solved by technology
Land requirements and equipment sizes for such plants are therefore very large, resulting in significant capital investment in building or expanding such plants
In addition, although the existing sewage treatment equipment includes monitoring of the water quality in the corresponding reaction tank, this monitoring method requires staff to take samples at designated locations, which is inconvenient to operate

The invention discloses circulating sewage treatment equipment. The equipment mainly comprises a pre-treatment unit 1, a biochemical reaction unit 2, a balance unit 3, a clarifying unit 4, a deep treatment unit 5, a water storage unit 6, a detection unit 7, a main control unit 8 and a PLC (Programmable Logic Controller) control unit 9; pre-treatment, secondary biochemical treatment, balance treatment, physicochemical treatment and deep treatment are matched, so that organic matters in sewage are sufficiently digested; meanwhile, almost pollutants in the sewage are removed, the sewage treatmentefficiency is improved and the treated water quality is excellent; meanwhile, multi-circulating treatment is utilized so that the utilization rate of the equipment is improved; a detection system, amain control system and a PLC control system also can be matched so that an intelligent and automatic control sewage treatment process is realized.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a circulating sewage treatment equipment and an automatic control system thereof. Background technique [0002] With the development of the economy and the continuous expansion of the population, the amount of sewage produced by human activities has increased year by year, and the sludge produced by sewage treatment has also continued to increase. At present, the activated sludge treatment method is the most widely used sewage treatment method, but the biggest drawback of this method is that the system needs to continuously discharge a large amount of sludge outward. Sludge is composed of a variety of microbial populations and organic and inorganic substances adsorbed on the bacterial micelles. It contains a very large amount of water, and there are also organic substances that are difficult to biodegrade, heavy metals, other salts, and a small amount of path...
