Quality appraisal of environmental protection equipment

environmental protection equipment refers to equipment that can effectively reduce pollutant emissions and meet environmental protection standards through various technical means. It is mainly used in industry, agriculture, transportation, construction and other fields to maintain ecological balance and avoid environmental degradation and ecological damage.
environmental protection equipment is widely used in various fields of production and life. For example, wastewater treatment equipment is widely used in chemical industry, textile, papermaking, printing and dyeing and other fields; air purification equipment plays an important role in industry, medical, daily life and other fields; environmentally friendly electronic waste treatment equipment is also widely used in electronics, communications and other fields.
In environmental protection equipment quality appraisal cases, Zhongke Testing can provide environmental protection equipment quality appraisal services.

1, mechanical performance appraisal
mechanical performance appraisal refers to testing and evaluating the appearance, size and structure of environmental protection equipment to judge its quality level and performance. This method is suitable for the quality identification of large equipment, such as filters and hydraulic equipment.
2, physical parameter identification
physical parameter identification is mainly through the detection of electrical, magnetic and other physical properties, including the resistance, capacitance, inductance, magnetism, energy size, etc. of the device. Suitable for electronic environmental protection equipment, such as air purifiers, etc.
3, chemical parameter identification
Chemical parameter identification refers to analyzing the chemical components in environmental protection equipment to judge its quality and environmental performance, including analyzing the pollutant characteristics, heavy metal content, pH and other factors of the equipment. It can be used for quality identification of most environmental protection equipment, especially in water treatment, gas treatment and other fields.
4, environmental protection treatment effect detection
environmental protection treatment effect detection refers to the monitoring and analysis of pollution emissions after treatment by environmental protection equipment. It is suitable for environmental protection equipment that needs to monitor the effect of the equipment, such as air purifiers, oil fume purifiers, etc.
5, safety inspection
safety inspection is mainly for the safety protection system. It judges its safety by testing the endurance and adaptability of safety protection devices, brakes, transmissions and other equipment components. Suitable for safety monitoring of different types of environmental protection equipment, such as environmental protection heat exchangers, desulfurization and denitrification, etc.

was entrusted by a court, and our company accepted the quality appraisal analysis of the environmental protection equipment involved in the case. The main analysis directions are as follows:
1. Causes of membrane clogging (whether related to high-concentration hazardous waste (hydrochloric acid + hydrofluoric acid) and heavy metal content);
2. Qualitative and quantitative identification of heavy metals in the pickling wastewater used to produce raw material zircon sand and zircon sand soaking solution.
quality analysis results: The
quality analysis expert group discussed the relevant information and on-site investigation and inspection of the environmental protection equipment involved and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
1. The cause of membrane clogging is that microorganisms such as bacteria and metal ions and fluoride ions work together to form poorly soluble compounds that are insoluble in water and ultimately block the RO membrane pores. RO membrane blockage is related to organic matter, bacteria, heavy metals and other factors.
2, zircon sand, the raw material for production, contains heavy metal elements such as iron, nickel, chromium, lead, etc.; due to on-site conditions, it is impossible to sample the zircon sand soaking liquid.
