Chemical industry pollution remediation equipment

Groundwater is a precious freshwater resource for human beings. However, with the continuous development of social industrialization, wastewater discharge, industrial waste, agricultural irrigation, landfill leakage, and damage to transportation pipelines and storage tanks for petrochemical raw materials can all cause groundwater pollution, exacerbating the already tight water shortage problem. It also poses a serious threat and challenge to human health, food safety, drinking water safety, regional ecological environment, sustainable economic and social development, and even social stability. Groundwater restoration has become an environmental issue that is currently of great concern to the public and society.

Chemical industry pollution remediation equipmentProcess flow description:

Primary pretreatment system: using quartz sand multi-media filter, the main purpose is to remove harmful substances such as sediment, manganese, rust, colloidal substances, mechanical impurities, suspended solids and other particles in water with a particle size of more than 20UM that are harmful to the human body. The automatic filtration system adopts an imported Fulike controller, which can automatically perform a series of operations such as backwashing and forward flushing. At the same time, the equipment has a self maintenance system and low operating costs. The filter materials mainly include PPF, AC coconut carbon, etc.

Second level pretreatment system: using activated carbon filters to remove pigments, odors, and large amounts of biochemical organic matter from water, reducing residual chlorine levels, agricultural residue pollution, and other harmful pollutants to human health. The automatic filtration system adopts an imported Fulike controller, which can automatically perform a series of operations such as backwashing and forward flushing.

The third level pretreatment system uses cationic resin to soften water, mainly removing hardness from the water. The hardness of water is mainly composed of calcium (Ca2+) and magnesium (Mg2+) ions. When the raw water containing hardness ions passes through the resin layer, Ca2+and Mg2+in the water are exchanged and adsorbed by the resin, and sodium Na+ions are released at the same time. The water flowing out of the water softener is softened water without hardness ions. Thus effectively preventing fouling of reverse osmosis membranes. The system can automatically perform recoil, forward thrust, etc. And intelligent resin regeneration can be carried out to extend the service life of the system.

The fourth level pretreatment system: uses a 5-micron aperture precision filter to further purify the water, optimizing its turbidity and chromaticity. Ensure the inlet requirements of the RO system. The main system of the purified water equipment adopts reverse osmosis technology for desalination treatment. The pore size of the reverse osmosis membrane is only 0.0001 microns, which can remove harmful soluble solids, bacteria, viruses, etc. The desalination rate is over 99.6%, producing purified water that meets the standards. The main part includes a security filter, a high-pressure pump, and a reverse osmosis membrane. The security filter is the fourth stage pretreatment system above, and the high-pressure pump is one of the core equipment on the main machine, providing sufficient pressure for the reverse osmosis membrane elements to overcome osmotic pressure and operating resistance, and meet the rated water output of the device.

Ozone sterilization system has strong oxidizing properties and four major functions: sterilization, oxidation, decolorization, and deodorization. When used for water disinfection, at a concentration of 4mg/l, it can kill all bacteria in 0.5-1 minute. At the same time, ozone dissolves in water to form oxygen rich water, ensuring the purity and freshness of the water without losing its activity.

Product Introduction:

We are always committed to application-oriented work

Wise planning, the use of new transportation technologies, well-trained assembly teams, and fast availability are the foundation of our work to meet high requirements. Remote monitoring and 24-hour backup service ensure the reliability of factory operation.

The example process, desorption, and desorption tower have the following advantages: pollutants are transferred from the liquid phase to the gas phase, and the contaminated exhaust gas can then be economically and efficiently treated in a separate purification stage. To eliminate pollutants, contaminated water is extracted to the top of the desorption column. Under counter current conditions, normally unobstructed ambient air will flow from the bottom of the column to the top of the column. During this process, pollutants transition from the liquid phase to the gas phase. Water is discharged from the bottom of the tower, which does not contain volatile pollutants, while there are pollutants rich in air at the top of the tower. If necessary, water can be purified in a combination of gravel filter and wet activated carbon filter or biological grade filter, and then discharged into the canal. For polluted air, there are more possible purification stages: pure air activated carbon adsorber, solvent recovery, catalytic combustion. The current water treatment capacity of the column used is 2 to 340m ³/h. In fact, an additional three columns are connected in series to remove substances that are difficult to desorb from water.
