Knowledge of leachate treatment equipment

The composition of the leachate is complex, the concentration of pollutants is high, and the treatment difficulty is high. The debugging and start-up process is slow, and it is greatly affected by environmental conditions and water quality and quantity. In order to ensure the normal and efficient operation of the leachate treatment system and ensure that the treated leachate meets the discharge standards, it is necessary to carry out debugging and operation work. The debugging and operation of leachate mainly include: maintenance, optimization of design ideas and parameters for leachate treatment; Establish archival materials on relevant measures and measures, provide suggestions on the rationality of the design and operation precautions of relevant machinery, equipment, and instruments, and investigate and reasonably solve common problems.

The debugging of the leachate treatment system is based on grasping the basic engineering overview. Firstly, it is necessary to conduct load testing on the single equipment, unit system, and the entire treatment process in sequence, solve various problems that affect continuous operation, adjust operating parameters, and make the effluent of the leachate treatment system reach the design scale; Secondly, it is necessary to determine the process control parameters that are in line with the actual inflow water quality and quantity, and minimize energy consumption while ensuring that the effluent water quality meets the standard; Finally, it is necessary to develop process control procedures and provide relevant training to production and management personnel to guide them in establishing production related systems and daily monitoring mechanisms to ensure the normal operation of the filtrate system.

Leachate treatment equipment

1、 Preparation for commissioning of leachate treatment equipment

Debugging preparation is all necessary preparatory work that needs to be done throughout the entire process of system debugging to ensure that the debugging process proceeds smoothly as planned. This mainly includes the acceptance evaluation of construction quality, relevant debugging measures, formulation of debugging plans, personnel and material allocation, equipment (including fixtures, measuring tools, tools, etc.) preparation, etc.

1. Construction quality acceptance evaluation

The leachate project of the Fukou garbage incineration plant, as a subsystem of the Fukou garbage incineration power generation project, follows different scales from the traditional sewage industry. In terms of construction quality acceptance and evaluation, the relevant standards of the thermal power industry are mainly followed.

2. Construction quality acceptance evaluation

Before debugging, the construction quality of the leachate equipment should be inspected and evaluated, mainly including civil construction, installation of thermal instruments and control systems, electrical installation, pipeline installation, welding, etc.

3. Installation of thermal instruments and control devices

The Standards for Quality Maintenance and Evaluation of Thermal Power Construction (Thermal Instruments and Control Devices) is the basis for the quality maintenance and evaluation of thermal instruments and control devices in thermal power engineering construction. On site maintenance should follow the L/T 5190.5-2004 Technical Specification for Acceptance of Power Construction Measures (Thermal Instruments and Control Devices) for evaluation, and the quality level should be evaluated based on the acceptance results.

4. Electrical installation engineering

The installation of electrical equipment should be based on the engineering situation, and the construction unit should prepare the scope of quality inspection and evaluation for the undertaken project according to the General Rules for Quality Acceptance and Evaluation of Electrical Equipment Safety Engineering (DL/T 5161.1-2002). The supervision unit shall review and summarize the scope of engineering quality inspection and assessment prepared by each construction unit, and execute it after confirmation by the construction unit. The data should be calculated based on the necessary information in each sub project, and the data should be consistent with the actual data.
