Description
Technical Field
The utility model relates to an integrated form waste water treatment pond and biochemical treatment system.
Background
The wastewater stream is typically treated by a variety of processes to remove organics, ammonia nitrogen, total phosphorus, suspended solids, and any other undesirable contaminants therefrom. For example, the wastewater stream may be contacted with activated carbon for a period of time effective to remove an amount of chemical oxygen demand therefrom. In some cases, activated carbon is further combined with biomass suitable for removing readily biodegradable organics from wastewater streams. A biochemical treatment system combining powder activated carbon adsorption and an activated sludge process combines biological treatment and activated carbon adsorption into a single synergistic step. Superior contaminant removal efficiency is achieved. The biochemical treatment system combining powdered activated carbon adsorption and activated sludge processes is usually combined with a humid air regeneration system that regenerates the waste carbon from the biochemical treatment system using high temperature and high pressure conditions while oxidatively destroying the biomass in the waste carbon sludge. In an effort to increase the efficiency of contaminant removal to meet the increasingly stringent requirements of certain jurisdictions, multi-stage biochemical processing systems have been developed. The multi-stage biochemical treatment system operation includes the removal of biodegradable organics and some refractory organics in a first stage by a combination of biochemical treatment and carbon adsorption; and finally finely processing the pollutants in the second stage by further carbon adsorption to reach the emission standard.

In order to make the objects, technical solutions and advantages of the present invention clearer, the following embodiments further describe the present invention in detail.
Fig. 1 is a schematic structural view of an integrated wastewater treatment tank 100 of a biochemical treatment system combining a powdered activated carbon adsorption and an activated sludge process according to a first embodiment of the present invention. The overall pool shape shown by figure 1 is rectangular. In another embodiment, not shown, the pool shape has four rectangular corner chamfered corners. In the embodiment of fig. 1, an integrated wastewater treatment tank 100 for a combined powdered activated carbon adsorption and activated sludge process biochemical treatment system provided by the present invention includes a plurality of functional zones that provide different wastewater treatment technologies. One of the plurality of functional zones is a water distribution zone 1 for collecting wastewater to be treated, such as industrial wastewater, which enters the water distribution zone 1 of the integrated wastewater treatment tank 100 to realize supply of the wastewater to be treated to the water distribution zone 1. After entering the water distribution zone 1, the wastewater to be treated is mixed with the aerobic zone return liquid, the sedimentation zone return sludge, powdered activated carbon, nutrient salt medicament and the like, a mixed solution is formed by adding nutrient salt, acid and alkali, new activated carbon or regenerated activated carbon and other materials provided by a wet oxidation regeneration system, and the mixed solution is distributed to other downstream functional zones for further treatment by other functional zones of the plurality of functional zones.
Other functional zones among the plurality of functional zones in the integrated wastewater treatment tank 100 include biochemical zones, namely an anoxic zone 2 and an aerobic zone 3 for implementing biological treatment techniques, a degassing zone 4 for removing waste gases from mixed liquor, and a settling zone 5 for separating suspended matter. For example, denitrification treatment of the mixed liquor from upstream can be performed in the anoxic zone 2, and removal treatment of organic matter and ammonia nitrogen from the mixed liquor from upstream can be performed in the aerobic zone 3. The efficiency of the treatment is increased by mechanical plug flow agitation in the anoxic zone 2, in this example, the influent nitrate nitrogen is high, internal circulation is formed in the functional zone, and the denitrification gradient is reduced. Aeration is performed in the aerobic zone 3, for example, by coarse aeration or other means. Polyacrylamide PAM is added in the degassing zone 4. The settling zone 5 is realized, for example, as a square basin with a basin bottom chamfer, provided with a centrally driven sludge scraping and sucking machine, fed by a central tube, and provided with a sludge collecting cylinder in the center of the basin bottom. After the mixed solution is subjected to biochemical treatment and activated carbon adsorption treatment in biochemical areas including an anoxic area 2 and an aerobic area 3, the mixed solution is subjected to solid-liquid separation in a settling area, and the separated supernatant effluent is subjected to downstream device treatment or is discharged after reaching the standard. Treated wastewater treated by the integrated wastewater treatment tank 100 or effluent of a biochemical treatment system is drawn from the settling zone 5 in the direction of the arrow shown in the drawing. Excess sludge is led to a thickening tank in the sedimentation zone 5, and a sludge discharge return line to the water distribution zone 1 is provided in the sedimentation zone 5.

A wall-through pump or stripping device is arranged on the at least one separating wall 10, by means of which mixed liquor is supplied from a first functional zone of the plurality of functional zones via the separating wall 10 to a second functional zone of the plurality of functional zones, which are separated by the at least one separating wall 10. For example, the water distribution zone 1 is separated from the anoxic zone 2 by a partition wall 10 in the flow direction of the mixed liquor, so that the mixed liquor passes through the partition wall 10 from the water distribution zone 1 into the anoxic zone 2. In order to achieve a further reduction in the footprint of the integrated wastewater treatment basin 100, the distribution zone 1, the anoxic zone 2 and/or the aerobic zone 3 and the degassing zone 4 all have a common dividing wall 10 with the sedimentation zone 5, whereby the sedimentation zone 5 is surrounded by a plurality of other functional zones, as in the spatial arrangement of the embodiment shown in fig. 1. In the embodiment in which an anoxic zone 2 is provided, wall-penetrating pumps or stripping means are provided only between the water distribution zone 1 and the anoxic zone 2, and no wall-penetrating pumps or stripping means are provided on the dividing walls, for example between the anoxic zone 2 and the aerobic zone 3, between the aerobic zone 3 and the degassing zone 4, between the degassing zone 4 and the water distribution zone 1, and between the degassing zone 4 and the precipitation zone 5, but for providing the mixture from one functional zone to another functional zone, the mixed liquor is provided in a gravity-free flow from a first functional zone of the plurality of functional zones to a second functional zone of the plurality of functional zones via the dividing wall 10, the first functional zone and the second functional zone being separated by the at least one dividing wall 10.
Fig. 2 is a schematic structural view of an integrated wastewater treatment tank of a biochemical treatment system combining a powdered activated carbon adsorption and an activated sludge process according to a second embodiment of the present invention. In this embodiment, the anoxic zone 2 in the biochemical zone is separated from the water distribution zone 1, the aerobic zone 3 and the precipitation zone 5 by a partition wall 10. Moreover, since the influent nitrate nitrogen is normal, the anoxic zone 2 of FIG. 2 does not require internal circulation as compared to the anoxic zone of FIG. 1.
Fig. 3 is a schematic structural view of an integrated wastewater treatment tank of a biochemical treatment system combining a powdered activated carbon adsorption and an activated sludge process according to a third embodiment of the present invention. In this embodiment, the area of the anoxic zone 2 shown in fig. 1 and 2 is changed to an aerobic zone, since no denitrification reaction is required, i.e. the biochemical zone in this embodiment consists of the aerobic zone 3, which in turn forms an integrated aerobic zone with the aerobic zone 3 shown in fig. 1 and 2, as shown in fig. 3, in which the aeration system is arranged and the partition walls of the raw effluent are eliminated. For example, in the case of a biochemical treatment system combining multistage powdered activated carbon adsorption and activated sludge process, generally, since the biochemical treatment system combining powdered activated carbon adsorption and activated sludge process of the second stage does not require denitrification reaction, the system of the second stage can adopt a tank-type configuration shown in fig. 3.
