Abstract
The utility model discloses an automatic adjustment system for efficient removal of organic pollutants. The automatic adjustment system comprises a water inlet end, a pretreatment section, a biochemical treatment section, a sedimentation tank sedimentation section, a post-treatment section and a water outlet in sequential connection. The biochemical treatment section is provided with aeration equipment, the sedimentation tank sedimentation section is provided with a sludge tank for storing sludge in a sedimentation tank, a first COD (chemical oxygen demand) online monitor is connected between the water inlet end and the pretreatment section, a second COD online monitor is connected between the post-treatment section and the water outlet, and the aeration equipment, the first COD online monitor and the second COD online monitor are all connected with a PLC (programmable logic controller) control center. The automatic adjustment system is simple in structure and convenient to use, COD values of incoming and outgoing water quality are detected by the COD online monitors, opening and closing of the aeration equipment and sludge backflow equipment are controlled by the PLC control center according to the COD values, oxygen supply and energy consumption of a backflow system can be reduced, and discharge of high-quality treated water is guaranteed.
Description
Technical field
The utility model relates to the municipal sewage treatment field, specifically is the efficient varitrol of removing of a kind of organic pollutant.
Background technology
The urban sewage treatment system of existing municipal sewage plant has generally comprised pretreatment stage, biochemical treatment stage, settling tank precipitate phase and post-processing stages; Rubbish during pretreatment stage is disposed of sewage, foreign material; The biochemical treatment stage is carried out biochemical treatment with sewage; Mud in the sewage of settling tank precipitate phase after with biochemical treatment carries out precipitation process, and the mud in the settling tank shovels out through mud scraper and pours in the sludge sump, and fluid carries out last purifying treatment through post-processing stages.Its chemical requirement of water quality (COD value) after but this quadravalence purification system is handled is often higher, is not suitable for the lake and admits, and can not change the trend of lake eutrophication.In order to realize the standard of chemical requirement,, realize the standard of COD value now through to the control of biochemical treatment stage oxygen-supplying amount and the control of mud quantity of reflux, but because this mode is not robotization control, its troublesome poeration, and expend the energy.
The utility model content
The technical problem that the utility model will solve provides the efficient varitrol of removing of a kind of organic pollutant, guarantees the COD standard of effluent quality, and time saving and energy saving, energy-saving and cost-reducing.
The technical scheme of the utility model is:
The efficient varitrol of removing of organic pollutant; Comprise the feed-water end, pretreatment stage, biochemical treatment stage, settling tank precipitate phase, post-processing stages and the water side that connect successively; The described biochemical treatment stage is provided with aerator; Described settling tank precipitate phase is provided with the sludge sump that is used to store mud in the settling tank; Be connected with a COD on-line monitoring appearance between described feed-water end and the pretreatment stage, be connected with the 2nd COD on-line monitoring appearance between described post-processing stages and the water side, described aerator, a COD on-line monitoring appearance and the 2nd COD on-line monitoring appearance all are connected with PLC control center.
Be provided with the mud refluxing unit that mud in the sludge sump is back to the biochemical treatment stage in the described sludge sump, the mud refluxing unit is connected with described PLC control center.
The advantage of the utility model:
Detect the COD value of water inlet and effluent quality by COD on-line monitoring appearance; Give PLC control center with data transmission then, when the COD value was high, PLC control center control aerator and mud refluxing unit were opened; When the COD value reaches standard; Control aerator and mud refluxing unit are closed, and reduce oxygen supply and return-flow system energy consumption, and have guaranteed the good discharging of water quality treatment.
Description of drawings
Fig. 1 is the structural principle block diagram of the utility model.
Embodiment
See Fig. 1; The efficient varitrol of removing of organic pollutant; Comprise the feed-water end, pretreatment stage, biochemical treatment stage, settling tank precipitate phase, post-processing stages and the water side that connect successively;, the biochemical treatment stage is provided with aerator, and the settling tank precipitate phase is provided with the sludge sump that is used to store mud in the settling tank; Be provided with the mud refluxing unit that mud in the sludge sump is back to the biochemical treatment stage in the sludge sump; Be connected with a COD on-line monitoring appearance between feed-water end and the pretreatment stage, be connected with the 2nd COD on-line monitoring appearance between post-processing stages and the water side, aerator, mud refluxing unit, a COD on-line monitoring appearance and the 2nd COD on-line monitoring appearance all are connected with PLC control center.
During use, a COD on-line monitoring appearance and the 2nd COD on-line monitoring appearance detect the COD value of feed-water end and water side water quality respectively, give PLC control center with this data transmission then; When the COD value was higher, PLC control center control aerator and mud refluxing unit were opened the operation of carrying out oxygen supply and mud backflow, when the COD value reaches the water quality emission standard; Promptly control aerator and mud refluxing unit adjustment operation; Guaranteed the saving of the energy, and the equipment switching is time saving and energy saving for robotization control.
