Embodiment Construction
[0056] In order to improve the stability of the water inlet pressure of the filtration membrane group, the embodiments of the present invention provide a leachate treatment control method, device, system and sewage treatment equipment. In this technical solution, a water inlet pressure sensor is added, and when the current water inlet pressure is not less than the set first water inlet pressure threshold, the pressurization device is controlled to reduce the amount of pressurization of the leachate to be treated, therefore, water inflow can be prevented Excessive pressure causes the shutdown of the leachate treatment system, relatively improves the treatment efficiency of leachate, and also increases the service life of the equipment. In order to make the purpose, technical solution and advantages of the present invention clearer, the following specific examples are given to further describe the present invention in detail.

The invention relates to the technical field of sewage treatment and discloses a method, device and system for the treatment control of percolate and a sewage treatment device. The system comprises a pressurizing device, a filtration membrane group, a water inlet pipe, a water outlet pipe, an inlet water pressure sensor and a control device, wherein the pressurizing device is used for pressurizing the percolate to be treated, an outlet of the pressurizing device is connected with an inlet of the filtration membrane group through the water inlet pipe, and an outlet of the filtration membrane group is connected with the water outlet pipe; the inlet water pressure sensor is arranged on the water inlet pipe and is used for detecting the current inlet water pressure of the filtration membrane group; the control device is in signal connection with the pressurizing device and the inlet water pressure sensor respectively and is used for controlling the pressurizing device to reduce the pressurizing volume for the percolate to be treated when the current inlet water pressure is not lower than a set first inlet water pressure threshold. By adopting the technical scheme of the invention, the occurrence of a phenomenon that a percolate treatment system is in failure due to too high inlet water pressure can be prevented, the treatment efficiency of the percolate is increased, and the service life of the device is prolonged.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a leachate treatment control method, device, system and sewage treatment equipment. Background technique [0002] Leachate is a secondary pollutant produced in the process of domestic waste landfilling. Its water quality and quantity vary greatly and are greatly affected by factors such as waste composition, landfill time, and landfill methods. Therefore, the leachate treatment process is relatively complicated. [0003] The existing leachate treatment system is mainly composed of a regulating tank, a primary filtration system, a two-stage membrane separation system, a clean water tank and a concentrate tank, among which the membrane separation system is the core system that affects the entire treatment effect. Membrane separation system is mainly composed of filter membrane group, inlet and outlet valves and sensors. The leachate to be treated, that is, the raw water, ...
