Description
Technical Field
The utility model relates to the technical field of landfill leachate treatment, in particular to a cleaning device for an anaerobic system.
Background
The landfill leachate treatment is a difficult problem of domestic high-concentration sewage treatment, and the influent water quality is large in change, complex in component and high in organic matter concentration; since wastewater contains a large amount of inorganic salt ions (Ca 2+、Mg2 ions), the scale ions can co-act with anaerobic metabolites (NH 4+) and phosphorus released by phosphorus accumulating bacteria (PO 4 3-) to form a black crystal, namely magnesium ammonium phosphate commonly known as struvite. The black scaling material is insoluble in water, once the black crystal is formed, the black crystal is easily attached to a pool wall, a pipe wall and a three-phase separator to form a black crystal layer, a distribution pipe network of an anaerobic system is blocked, so that the treatment efficiency of the anaerobic reactor is reduced, the pressure of a circulating pipeline is increased, the safety risk of the anaerobic reactor is increased, and finally the anaerobic reactor is forced to be stopped and overhauled, thereby becoming a common problem in the percolate treatment industry.
Anaerobic system branch pipe network includes among the prior art: the biogas collecting pipe is tangentially connected with the middle part of the gas-liquid separator to form a biogas rising collecting pipe, the central pipe is connected with the bottom of the gas-liquid separator to form a liquid descending pipe, and a water outlet of the central pipe is arranged at the lower part of the anaerobic reactor. The inner circulating pipe is connected with the outer circulating pipe, the outer circulating pipe is arranged at the lower part of the anaerobic reactor and connected with the tank body in a tangential direction, and the inner circulating pipe is arranged between the two layers of three-phase separators and is provided with a water collecting bucket. The water outlet pipe is arranged at the top of the anaerobic reactor, one end of the water outlet pipe is connected with the overflow weir, and the other end of the water outlet pipe is connected with the anaerobic water outlet pool. The mud discharging pipe is arranged at the bottom of the anaerobic reactor, and the mud bucket is arranged at the bottom of the tank. In the prior art, along with the increase of the operation time, the scaling crystallization of the anaerobic system distribution pipe network and the connected equipment becomes more and more serious, and the anaerobic operation efficiency is continuously reduced.
The existing cleaning method can be divided into manual cleaning and mechanical cleaning modes, and the existing manual cleaning and descaling modes are to use a large hammer, an iron pipe and the like to shock a pipeline to strip and remove the scale. Because the scaling substances are enriched in annual ring shapes, the scaling substances can be peeled off layer by knocking in the direction perpendicular to the direction of the calcium scale, and the scaling substances are broken like glass piece by piece. And the manual descaling has the following defects:
1. The manual cleaning is time-consuming and labor-consuming, and the pipeline installed in the internal equipment of the anaerobic reactor cannot be manually operated due to the fact that the operation space is not available;
2. For the part with higher pipeline height in the anaerobic reactor, a scaffold is needed to provide an operation space, so that the risk of high-altitude falling is caused;
3. the pipeline is directly knocked, and the surface of the pipeline is damaged.
Existing mechanical cleaning modes such as cleaning and descaling of high-voltage equipment: the high-pressure cutting and cleaning equipment is used for breaking or cutting the calcium scale into blocks and stripping the blocks from the pipeline, so that the purposes of removing the calcium scale and dredging the pipeline are achieved. However, the cleaning and descaling of the high-voltage equipment have the following defects:
1. The anaerobic reactor has high adhesion of scaling substances, the cleaning pressure exceeds the working capacity of most high-pressure cleaning equipment, the ultra-high-pressure cleaning equipment is needed, the cleaning pressure is up to 200Mpa, and the high-pressure cleaning vehicle does not have operation feasibility;
2. The pressure of the high-pressure flushing is inversely proportional to the pipe diameter and the length, the longer the pipeline which needs to be cleaned of calcium scale is, the greater the difficulty of the operation by using the high-pressure pipeline is, the greater the pipe diameter is, the pressure is reduced when the high-pressure gun head is used for the descaling operation in the pipeline, and the poorer the cleaning effect is.
The maintenance can also adopt a cleaning mode of combining machinery and manpower, but the problems of high operation risk, low efficiency and difficult thorough cleaning still exist.
