Problems solved by technology

[0005] Aiming at the problems that the existing water inflow and outflow control methods of anaerobic leachate treatment systems require cumbersome on-site manual operations and high labor intensity, the present invention provides a new water inflow and outflow control method for anaerobic leachate treatment systems. The novel leachate anaerobic treatment system inflow and outflow control method uses the PLC system to automatically and sequentially control the inflow and outflow of the anaerobic treatment system, thereby improving the efficiency of operating personnel and reducing labor intensity

Embodiment Construction

[0020] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other examples, some technical features known in the art are not described in order to avoid confusion with the present invention.

[0021] In the actual anaerobic treatment of leachate, a certain amount of leachate needs to be regularly fed into the anaerobic treatment system (anaerobic tank, sometimes a pool), and then the leachate is treated for a certain period of time by circulating in the anaerobic treatment system. , to remove most of the organic matter in the leachate. After the reaction is completed and the sampling is qualified, the water can be discharged into the aerobic reaction tank. However, in the control of the inflow and outflow of the existing anaerobic treatment system, t...

Abstract

The invention relates to a water feeding and discharging control method of a leachate anaerobic treatment system. According to the water feeding and discharging control method of the leachate anaerobic treatment system, a PLC system is adopted for sequentially controlling water feeding and discharging of the leachate anaerobic treatment system. The water feeding and discharging control method of the leachate anaerobic treatment system has the advantages that the PLC system is adopted for automatically and sequentially controlling the water feeding and discharging of the leachate anaerobic treatment system, so that the water feeding and discharging control method of the leachate anaerobic treatment system is more intelligent compared with a field manual control method, control is simple, time and labour are saved, efficiency of operators is improved, labour intensity is reduced, and equipment can be automatically monitored and protected in real time.

Description

technical field [0001] The invention relates to the field of leachate treatment, in particular, the invention relates to a method for controlling inflow and outflow of a leachate anaerobic treatment system. Background technique [0002] At present, landfill technology or incineration technology is mainly used for the treatment of municipal solid waste in my country, and landfill leachate will be generated in the process of landfill or incineration treatment. The concentration of CODCr in landfill leachate is about 6000-70000mg / L, NH 3 -The concentration of N is about 1000-2500mg / L, and it contains a large amount of dissolved solids (sodium, calcium, chloride, sulfate, etc.), which is a kind of water quality with large changes in water quantity, imbalance of microbial nutrient elements, extremely complex components, and pollutant concentration. High organic wastewater, accompanied by a very heavy rotten odor, if not properly treated, will cause serious pollution to the surro...
