Description
Technical Field

Water eutrophication is a difficult problem in water environment pollution treatment at present, and is one of the most important water environment problems in the whole world. Along with the acceleration of industrialization and urbanization processes in China, the problem of urban river and lake eutrophication is increasingly serious, so that the water quality of a water body is deteriorated, and even unpleasant odor is emitted.
The root tracing is mainly that many domestic internal lakes historically contain a sewage receiving water body, exogenous pollutants are continuously deposited and enriched, and the ecological function of the water environment is degraded, so that the quality of the water environment in the region is rapidly deteriorated.
In order to improve the water environment, measures such as emergency fresh water supplement, sediment desilting or sediment dredging, water aeration oxygenation, ecological floating beds and the like are adopted to treat endogenous pollution.
Theoretically, the method can only reduce the pollution of nitrogen and phosphorus but not reduce organic pollutants in water and bottom mud when planting light energy autotrophic emergent, floating, submerged and other aquatic plants.
Organic pollutants in the water are continuously and slowly mineralized through an algae-bacteria symbiotic system, when the background pollutants in the water exceed the environmental capacity, the requirement of water environment treatment is difficult to meet only by a natural ecological method, and the organic pollutants are reduced by artificial strengthening measures such as sediment dredging, water aeration and oxygen charging. At the same time, sediment dredging generates a large amount of dangerous waste, requires ex-situ transfer and disposal, and creates a new source of pollution if storage or disposal measures are inappropriate.

Specifically, the method for the in-situ treatment of the water environmental pollution by using the hydraulically driven controlled cycle in-situ biological regeneration device is described by combining the following steps with the figure 1:
the main working area of the hydraulic drive controlled circulation in-situ biological regeneration device comprises two internal circulations which are connected in series in space, wherein liquid in the second guide cylinder 9 and liquid in the external space of the second guide cylinder circularly flow to generate upper-level internal circulation, and liquid in the first guide cylinder 3 and liquid in the external space of the first guide cylinder circularly flow to generate lower-level internal circulation.
The liquid circulation energy generated by the upper-stage internal circulation flow and the lower-stage internal circulation flow pushes the second driving wheel of the first driving turbine to move, so that the hydraulic driving is realized, the device can be started to work without external power input, and the purpose of saving energy is achieved.
Meanwhile, according to the moving direction of the water flow, the inner spaces of the first guide cylinder 3 and the second guide cylinder 9 form an ascending area, and the outer space corresponding to the ascending area is a descending area. The conical cylinder 7 is used as a demarcation point, and is positioned in an upper layer called an upper layer upflow zone I and an upper layer downflow zone II; the lower layer is called a lower layer upflow region III and a lower layer downflow region IV; the space between the lower connecting plate and the mud surface is a mud-water mixing area V.
According to the characteristics of the water flow environment, the internal environment of the guide shell where the upper upflow zone I and the lower upflow zone III are located is mainly an aerobic environment, and the external environment of the guide shell where the upper downflow zone II and the lower downflow zone IV are located is mainly an anoxic environment and an anaerobic environment.
The aeration pump 14 is started, and the loading airflow enters the main guide cylinder 1 through the lower annular aerator 19, so that the liquid-gas content in the lower ascending flow area III is higher, the density of the mixed solution is low, and the liquid-gas content in the lower descending flow area IV is low, and the density of the mixed solution is high. Due to the action of the loading air flow, the density difference exists between the gas-liquid mixtures of the lower ascending flow area III and the lower descending flow area IV, so that the lower internal circulation between the lower ascending flow area III and the lower descending flow area IV is established. The lower-stage internal circulation flow is gradually enhanced along with the increase of the loading gas flow, and the hydraulically controlled circulation is realized. Meanwhile, the loaded airflow in the lower layer upflow zone III enters the upper layer upflow zone I after being collected and distributed by the cone 7, so that the upper layer internal circulation is established. The superior internal circulation water flow and the subordinate internal circulation water flow respectively drive the current-level driving wheel to rotate and form resultant force, so as to drive the central shaft 12 to rotate, the central shaft 12 rotates to drive the stirring mechanism 20 connected to the bottom of the central shaft to move, the stirring mechanism 20 fully stirs the sediment on the surface layer of the mud surface of the water environment to suspend the sediment, and the suspended sediment is forced to participate in superior internal circulation and subordinate internal circulation under the clamping effect of the subordinate internal circulation water flow.
The suspended bottom sludge is carried by the upper-stage internal circulation water flow and the lower-stage internal circulation water flow to continuously and circularly flow, and the suspended bottom sludge is subjected to strong turbulence when alternately flowing through the lower-layer upflow zone III and the upper-layer upflow zone I, so that the secondary dissolution and mass transfer effects of the bottom organic matters in the bottom sludge are generated, and the exchange of the organic pollutants in the bottom sludge is realized.
After the method is adopted to carry out restoration treatment on the ecology in a certain area of the water environment, the support legs are lifted out of the fixed mud surface to push the floating pontoon, the hydraulically-driven controlled-circulation in-situ biological regeneration device is ectopically moved to a new area, and the hydraulically-driven controlled-circulation in-situ biological regeneration device carries out water environment ecological restoration in the new area.
In addition, the indigenous microorganisms in the bottom sediment alternately flow through aerobic and anoxic environments under the action of the upper-level internal circulation water flow and the lower-level internal circulation water flow, so that spatially laminated A/O and A are realized2the/O gradient is connected in series and alternately flows through anaerobic, anoxic and aerobic environments, so that the biodegradation of indigenous microorganisms in the bottom sludge is effectively enhanced to reach the bottomThe synchronous biodegradation and the restoration of background organic matters and nitrogen in the sludge and the water body realize the biological regeneration of organic pollutants in the bottom sludge.
In a word, the core of the water environment pollution in-situ treatment method is to construct two-stage internal circulation which is stacked and connected in series in space and is respectively a lower-stage internal circulation and an upper-stage internal circulation. The air flow is loaded in the lower-stage internal circulation at first, and the lower-stage internal circulation and the upper-stage internal circulation are sequentially driven under the action of the air stripping principle, so that the effects of two-stage circulation gradient series connection and level driving in space are realized. Meanwhile, the hydraulic internal circulation generates driving force when flowing through the two-stage driving wheel of the upwash zone, the stirring mechanism is driven to stir the surface sediment to suspend, the suspended surface sediment participates in the two-stage internal circulation under the entrainment of the lower-stage internal circulation water flow, and alternately flows through anaerobic, anoxic and aerobic environments, so that the spatial laminated A/O and A are realized2the/O gradient series effect effectively strengthens the biodegradation effect of indigenous microorganisms in the bottom sediment, achieves the purpose of in-situ synchronous degradation of organic matters and nitrogen in the bottom sediment and the water body, and realizes the bioremediation of organic pollutants.
