Description

Technical Field

[0001] The utility model belongs to the technical field of hazardous waste water treatment, and in particular relates to RO reverse osmosis water treatment equipment for hazardous waste water treatment. Background Art

[0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and even recycle and reuse wastewater to make full use of water resources. With the rapid development of the industrial economy, the amount of hazardous waste discharged in the industrial production process has increased day by day. Hazardous waste is referred to as hazardous waste. In the process of hazardous waste packaging and processing, hazardous waste wastewater needs to be treated and can only be discharged after meeting the standards to reduce pollution to the environment.

[0003] Hazardous waste disposal sites accept the following types of hazardous waste: viral, toxic, highly toxic, combustible, flammable, corrosive and chemically reactive wastes. Disposal methods include incineration, physical and chemical treatment, solidification / stabilization and landfill.

[0004] The wastewater treatment system in the prior art usually uses a physicochemical treatment subsystem to remove heavy metals. After precipitation, it is then passed through a biochemical treatment subsystem to remove organic matter. After precipitation, it needs to undergo secondary precipitation, and finally the supernatant is treated by an RO treatment device. The entire treatment process is complicated. At this stage, although the entire hazardous waste treatment is already quite mature. However, different hazardous waste treatment companies will assemble or modify RO treatment equipment according to their actual conditions. Therefore, this leads to uneven standards for RO treatment equipment, so that the company cannot control the cost and personnel investment in its maintenance. Furthermore, once a component needs to be replaced or repaired, it is difficult to quickly find a replacement product.

[0005] To this end, we propose a RO reverse osmosis water treatment equipment specifically for hazardous wastewater treatment. Utility Model Content

[0011] Furthermore, in order to facilitate the control of the qualified water coming out of the water outlet of the first mold body without being filtered by the second mold body, a solenoid valve is provided on the connecting conduit between the first mold body and the second mold body.

[0012] Furthermore, in order to save space for the entire device, the boost pump is connected to the precision filter through a Z-shaped conduit, and in order to monitor the pH value and conductivity of the precision filter inlet in real time, the water inlet of the precision filter is connected with an inlet pH meter and an inlet conductivity meter in sequence; in order to facilitate the timely discharge of excess air in the precision filter, an exhaust port is provided at the bottom of the precision filter. The model of the precision filter is YS5-40.

[0013] Furthermore, in order to detect the conductivity of the fresh water conduit in real time, a water outlet conductivity meter is provided at the water outlet of the fresh water conduit.

[0014] Furthermore, in order to monitor the pressure of the water inlet of the high-pressure pump at any time and prevent the pressure of the high-pressure pump from being too low, the water inlet of the high-pressure pump is provided with a water inlet pressure sensing device and a low-pressure protection device in sequence.

[0015] Furthermore, in order to prevent the waste water from the water inlet of the mold body from flowing back, a check valve is provided at the water outlet of the high-pressure pump.

[0016] Furthermore, in order to facilitate the cleaning of the pipelines of the entire device, a cleaning port and a water inlet pressure detector are provided in sequence at the connection between the high-pressure pump and the mold body.
