1、 Overview of river water treatment equipment products:

Integrating traditional sewage treatment procedures into an integrated sewage purification equipment, which integrates sedimentation, filtration, algae removal, purification, deodorization, decolorization, sterilization, disinfection, slag removal, and dredging. The maximum sewage treatment capacity of the equipment can reach 50-60 tons/hour, and the sewage treatment can reach one ton per minute. The water quality fully meets the national standards for reclaimed water or discharge, greatly shortening the sewage treatment process and revolutionizing traditional sewage treatment processes. The maximum sewage treatment capacity of river sewage treatment equipment can reach 50-60 tons/hour. It has the characteristics of continuous operation, automatic water supply and drainage, automatic slag discharge, compact structure, and high processing efficiency. Widely applicable and reliable in performance, it can be widely used for the treatment of industrial wastewater, landscape water bodies, and urban sewage, and can also be used as an emergency treatment device to respond to environmental emergencies.

2、 Characteristics of river water treatment equipment:

Large scale, large land occupation, large facility size, and multiple units, processing facilities are usually reinforced concrete structures. Therefore, it is required that the overall process composition be simple, and the composition of individual facilities should also be simplified. Pipeline interweaving and complex structures should be minimized as much as possible in order to reduce the total maintenance and management of facilities and equipment in the entire plant. Due to the large scale and high investment of river sewage treatment equipment and facilities, their sturdy and simple structure, long service life, good scale efficiency, low unit treatment cost, stable operation effect, and outstanding role in environmental governance, once it is determined to carry out river sewage treatment equipment engineering, it is necessary to carefully choose the process and consider the plan based on the characteristics of the sewage treatment equipment engineering, draw on the experience and technology of others, that is, the overall process composition should be simple, the single facility composition of the river sewage treatment equipment should be simplified, easy to maintain, easy to operate, energy consumption should be as low as possible, land occupation should be as low as possible, and the operation effect should be stable.

3、 River water treatment equipment Water treatment process:

The industrial wastewater treatment equipment uses large particle lightweight ceramic filter media to achieve low SS filtration rate in raw water under upward flow conditions, with a filtration head loss generally not exceeding 5kPa and small changes in filtration head before and after flushing. The requirements for the specific surface area index of the filter media are appropriately reduced, and the filtration rate is significantly increased to 16-20m/h, with an air-water ratio of 0-0.5. Under the dual action of biochemistry and interception of biofilm on the surface of large particle lightweight ceramic filter material, the pre treated effluent ammonia nitrogen is less than 0.5mg and greater than 0.5mg

4、 Treatment methods for river water treatment equipment:

1. Blow off method is a method of separation under alkaline conditions that utilizes the gas-liquid equilibrium relationship between the gas phase concentration and liquid phase concentration of ammonia nitrogen. It is generally believed that blow off is related to temperature PH、 The gas-liquid ratio is related.

2. The zeolite deamination method utilizes the exchange of cations in zeolite with NH4+in wastewater to achieve denitrification. The application of zeolite deamination method must consider the regeneration of zeolite, usually including regeneration liquid method and incineration method. When using incineration method, the generated ammonia must be treated. This method is suitable for the treatment of low concentration ammonia nitrogen wastewater, and the ammonia nitrogen content should be between 10-20mg/L.

3. Membrane separation technology is a method of ammonia nitrogen removal that utilizes the selective permeability of membranes. This method is easy to operate, with high ammonia nitrogen recovery rate and no secondary pollution. For example, the removal of ammonia nitrogen by gas water separation membrane. Ammonia nitrogen exists in dissociation equilibrium in water. As the pH increases, the proportion of ammonia in the form of NH3 in water also increases. At a certain temperature and pressure, the gaseous and liquid phases of NH3 reach equilibrium.

4. The MAP precipitation method mainly utilizes the following chemical reaction: Mg2++NH4++PO43-=MgNH4PO4. Theoretically, phosphate and magnesium salts are added to wastewater containing high concentrations of ammonia nitrogen in a certain proportion. When [Mg2+] [NH4+] [PO43-]>2.5 × 10-13, magnesium ammonium phosphate (MAP) can be generated to remove ammonia nitrogen from the wastewater.

5. Chemical oxidation is a method that uses strong oxidants to directly oxidize ammonia nitrogen into nitrogen for removal. Adding chlorine at break points is a method of using ammonia in water to react with chlorine to produce ammonia gas for deamination. This method can also have a sterilizing effect, but the residual chlorine produced can have an impact on fish, so residual chlorine removal facilities must be attached.
