Carbon Steel Aquaculture Wastewater Treatment Equipment 50m³/D SQYZ-50

1, Introduction to aquaculture wastewater treatment equipment:
The characteristics of aquaculture wastewater include high concentration of organic matter, abundant suspended solids, deep color, high concentration of NH3-N, a large amount of animal manure, and a large amount of pathogenic bacteria. The pollutants in sewage mainly exist in the form of solid and dissolved carbohydrates, resulting in high BOD5.CODcr.SS and chromaticity in the sewage. At the same time, sewage can be better biochemical, and it contains a large amount of nutrients such as N. P. Due to the fact that the solid residues in sewage are mainly organic matter, it is necessary to strengthen pre-treatment, perform solid-liquid separation, and reduce subsequent treatment loads.
In response to the difficulty in effectively treating aquaculture wastewater, we have designed and developed aquaculture wastewater treatment equipment with biochemical methods as the core. This equipment has a small footprint, strong targeting, is not affected by weather, stable effluent, and contains ammonia nitrogen pollutants in the water. And it has independent intellectual property rights, effectively solving the problems of difficult treatment and compliance of aquaculture wastewater.

2, Characteristics of aquaculture wastewater treatment equipment:
1. The integrated aquaculture sewage treatment equipment is made of carbon steel anti-corrosion treatment or stainless steel component splicing, with light weight, convenient transportation, and installation;
2. It adopts a corrosion-resistant structure made of fiberglass, carbon steel, and stainless steel, with characteristics such as corrosion resistance and aging resistance, and a service life of up to 15 years;
3. Save land without the need for building or heating. Realize equipment integration and reduce floor space;
4. No pollution, no odor, reducing secondary pollution;
5. It is not limited by the amount of sewage, and is flexible and can be used alone or in combination multiple times.
6. The entire equipment processing equipment is equipped with PLC automatic electrical control equipment and equipment fault alarm equipment, ensuring safe and reliable operation. In general, equipment only needs to be maintained in a timely manner, with low management costs and no need for dedicated personnel to manage it.

3, The working principle of rural aquaculture sewage treatment equipment:
The working principle of rural aquaculture sewage treatment equipment is to form a saturated dissolved air carrier with an appropriate amount of air and some return water in the dissolved air tank under a certain pressure (0.35-0.45Mpa). Through the release device, a large number of small bubbles are suddenly depressurized and quickly adhere to the flowing particles in the water. Emulsified oil. Bathing and coagulation react with flocs, resulting in a smaller proportion of flocs than water, forcing them to quickly float on the water surface, thereby achieving solid-liquid separation.
In the combination of complex and difficult wastewater treatment processes, air flotation treatment is also accompanied by attached aeration, which reduces surface activity and organic concentration, greatly reduces oxygen consumption, promotes further purification of wastewater, and provides water quality that is conducive to meeting standards for lower level treatment. The air flotation system of the air flotation machine integrates water collection, flocculation, separation, and collection, similar to traditional air flotation equipment. It has a stable flow chamber. Dissolved gas release chamber makes the treatment performance more stable and the effect more superior. Stable chamber: The raw water flow rate through the folding plate reaction is very high. If directly in contact with dissolved water, small bubbles will dissipate, affecting the effect of bubbles adhering to the floc, thereby reducing the efficiency of air flotation treatment. If a stable flow chamber is added, the kinetic energy consumption of turbulent raw water will enter the release chamber of dissolved gas water at a uniform rate, effectively ensuring the removal effect. Dissolved Gas Float Dissolved Gas Release Chamber: The dissolved gas release chamber is located in the same tank as the separation chamber. Separated in the middle, the dissolved gas water and the flocculated raw water adhere here, slowly rise, and enter the gas float separation chamber, ensuring the contact space and time of the flocculent small bubbles, so that the release rate of dissolved gas water reaches 80-100%.
2. For the air flotation equipment of industrial sewage treatment equipment, the air dissolution system is not only the heart of the air flotation equipment, but also the main component of the air flotation equipment. At this stage, gas and water are sucked into the inlet of the pump and mixed into gas soluble water through shear and pressure. Fully mix gas and liquid to reach saturation. The atmospheric content of the entire gas solubility system reaches 10%, and the gas solubility is 100%. When dispersed, microbubbles are evenly distributed, with an average bubble diameter of less than 30um. This gas dissolution system improves traditional air flotation and technological innovation, improves air flotation separation efficiency, and greatly reduces equipment production and operating costs.
The operation mode and speed of the slag scraper directly affect the water quality and sludge content of the floating water. The system adopts a rotary scraper, which is continuous and uniform. Scrape into the scum tank to reduce scum collision; In addition, the height adjustable scraper can better adapt to various operating conditions, and the industrial sewage treatment equipment integrates sewage treatment equipment to reduce the water content of sludge.
4. The control system adopts advanced electrical components (Delixi or Chint) to ensure long-term effective operation of the equipment.
