Glass sand wastewater treatment device

Glass sand wastewater treatment deviceIt is used to treat wastewater generated during glass processing, achieving wastewater purification through a combination of chemical and biological processes to ensure compliance with discharge standards. Its core lies in the comprehensive removal of fluoride, heavy metals, and organic pollutants, as well as reducing sludge production. The combination of biological contact oxidation and chemical precipitation effectively removes fluoride, ammonia nitrogen, total nitrogen, and suspended solids, while also possessing the ability to remove nitrogen and phosphorus. The treated wastewater can be recycled or discharged in compliance with standards, reducing environmental pollution. ‌The equipment is mostly made of fiberglass material, which is corrosion-resistant, lightweight, and easy to install and maintain. Modular design supports flexible layout and occupies a small area, especially suitable for areas with scarce land resources. Daily maintenance only requires inspection of components and cleaning of equipment surfaces, resulting in lower operating costs. The noise and odor control during the processing is good and meets modern environmental requirements. After treatment, wastewater can be recycled or discharged to meet standards, reducing resource waste and environmental pollution. Some equipment is also equipped with air flotation technology, which can remove small particles and further improve purification efficiency. ‌

Glass sand wastewater treatment deviceConfiguration:

Preprocessing system

Grille interception: using coarse/fine grids to remove large particle impurities (such as glass shards, plastics, etc.) from wastewater. ‌

Regulating pool: used for regulating water quantity and quality, equipped with a lifting pump to send wastewater to the subsequent treatment unit. ‌

Coagulation sedimentation system

Addition of coagulants: Common chemical agents such as polyaluminum chloride (PAC) and NaOH are used to promote the coagulation of suspended solids. ‌

Precipitation separation: Large particle impurities are removed by gravity settling, and some equipment uses inclined tube sedimentation tanks to improve efficiency. ‌

Deep processing system

Sand filtration/activated carbon filtration: further removes tiny suspended solids and impurities to ensure the quality of the effluent. ‌

Air flotation process: Air flotation technology is used to separate small particles (<50 μ m). ‌

Oxidation treatment: Optional technologies such as ozone oxidation and reverse osmosis can be used to remove recalcitrant pollutants. ‌

Sludge treatment system

Sludge thickening tank: Collect settled sludge, dehydrate it through a plate and frame filter press, and transport it outside. ‌

Sludge return: Some sludge can be returned to the regulating tank or used as fertilizer. ‌

The treatment technology of glass sand wastewater treatment equipment:

Electrochemical method: Electrochemical method utilizes current and electrode reactions to reduce or oxidize heavy metal ions in wastewater into harmless substances. This method can quickly and effectively remove metal ions from wastewater, and is easy to operate, with the characteristics of high efficiency and environmental protection.

Ozone oxidation: Ozone oxidation is an advanced oxidation technology that can decompose organic matter and recalcitrant substances in wastewater. Through the strong oxidizing properties of ozone, organic pollutants can be converted into carbon dioxide and water, thereby achieving the goal of purifying wastewater.

Reverse osmosis (RO) and electrodeionization (EDI) technologies: These technologies can effectively remove trace pollutants and recalcitrant substances from wastewater, ensuring that the wastewater meets discharge standards or reuse requirements. Reverse osmosis filters pure water through a semi permeable membrane, while electrodeionization further removes ions from water through an electric field.

Biological treatment technology, including activated sludge process and biofilm process, utilizes microorganisms to convert organic matter in wastewater into harmless substances, reducing organic pollution while minimizing harm to the environment and human health.

Physical treatment methods, such as precipitation, filtration, air flotation, etc., remove suspended solids, oils, and particulate matter from wastewater through physical means to ensure smooth subsequent treatment.

The application of these technologies not only improves the efficiency and quality of wastewater treatment, but also reduces secondary pollution during the treatment process, which meets environmental protection requirements.

The main components and working principle of glass sand wastewater treatment equipment:

The glass sand wastewater treatment equipment mainly consists of filters, sedimentation tanks, aeration devices, etc. The working principle of the equipment is to separate suspended solids, chemicals, etc. in wastewater through physical methods to achieve the purpose of purifying wastewater. The specific steps include:

Pre treatment: Remove large particles and suspended solids from wastewater through facilities such as grids and sieves.

Regulation and homogenization: Collect wastewater into a regulating tank for homogenization treatment of water quantity and quality.

Coagulation precipitation: Adding coagulants (such as polyaluminum chloride, ferric sulfate, etc.) to wastewater to cause suspended solids to agglomerate into larger particles and precipitate.

Filtration treatment: Sand filtration, activated carbon filtration and other methods are used to further remove suspended solids and impurities from wastewater.

Neutralization treatment: For wastewater with unstable pH values, neutralization treatment is carried out to adjust the pH value of the wastewater to neutral or close to neutral.

Deep processing: using techniques such as air flotation, ozone oxidation, and reverse osmosis to remove small particles and difficult to degrade substances.

The removal capacity of glass frosted wastewater treatment equipment:

Removal of suspended solids and particulate matter: The equipment removes large suspended solids from wastewater through a filter, and then enters a sedimentation tank for separation of suspended solids and water. In addition, the equipment also uses an SS dual selection machine for bidirectional sludge discharge, which can effectively separate large particles, easily precipitated suspended solids, and small particles, difficult to precipitate suspended solids

Chemical removal: Wastewater is treated with aeration through an aeration device to oxidize and decompose chemical substances in the wastewater. This treatment method can effectively remove harmful chemicals from wastewater

Disinfection treatment: Disinfect the wastewater through a disinfection device to ensure that it meets the discharge standards. Disinfection treatment can effectively kill pathogenic microorganisms in wastewater, ensuring that the treated wastewater is safe and harmless
