Description
Technical Field
The utility model relates to the field of sewage treatment, in particular to an automatic water quality sampling and detecting system; is a method for detecting the water quality index of the cross section of each treatment unit of a sewage treatment plant by using a novel water quality automatic sampling detection technology.
Background
The treatment process route of the sewage plant is a combination of each process section and generally comprises a pretreatment process section, a biochemical treatment process section and a deep treatment process section. Because the quality of the inflow water is continuously changed, especially the quality of industrial wastewater, the operation of a water plant usually detects the quality of the inflow water according to once-a-day sampling at present, and then judges whether the quality exceeds the standard or not and adjusts the operation according to online data of the outflow water.
In other words, the operation and process adjustment are mainly performed on site according to the water quality of the inlet water and the online data of the outlet water detected once a day, even if some sewage plants are provided with the online water inlet meters, many times, the water plants lack real-time water quality data for each process section in the process route, so that the actual operation effect of each process section cannot be judged, and the operation of each process section cannot be effectively adjusted and optimized; particularly, when the water inlet impact is received, the process adjustment is generally carried out until the abnormal occurrence of the online data of the water outlet is found, and the process adjustment carried out at the moment is quite short, so that the water plant has to face the risk of exceeding the standard of the water outlet.
Therefore, in actual operation, the common practice of the water plant is conservative operation, namely, an operation mode of providing higher DO concentration and higher biochemical sludge concentration by adopting larger medicament dosage and larger fan air quantity is adopted, so that the risk of exceeding the standard of water outlet caused by water inlet impact can be relieved to a certain extent in operation, but the operation cost is greatly increased by adopting the conservative operation mode.
In addition, in actual operation, in many cases, because of water quality, only increasing the dosage of the medicament or the air quantity cannot ensure that the discharged water stably reaches the standard, and increasing the air quantity and the sludge concentration is not beneficial to optimizing the discharged water quality in many cases, but can influence the actual effect of operation to a certain extent and increase the dosage of the medicament.
The traditional water quality on-line monitoring equipment utilizes the precipitation principle to separate out required water samples, and is commonly used for on-line monitoring of water inlet and outlet positions of a sewage plant. For a sewage plant adopting an activated sludge method, a required water sample is separated by utilizing a precipitation principle, the problems that the sample making period is prolonged due to long precipitation time, difficult supernatant is taken when activated sludge with poor precipitation performance is encountered, data distortion occurs to monitoring equipment because of the mud contained in the water sample and the like can occur.
Therefore, the automatic sampling and detecting system for water quality is developed, so that the section data of the middle process section or the process section of the sewage treatment plant is detected, the fine management of the sewage treatment plant is realized, the production operation regulation and control of the sewage treatment plant is guided, the water inlet impact is met, the stable standard reaching is ensured, the operation of the water plant on each process section is optimized, and meanwhile, the energy consumption and the medicine consumption are optimized, so that the automatic sampling and detecting system for the water quality has wide application prospect and value.
