1. Overview

The inclined tube sedimentation flocculation biochemical integrated machine is a water treatment equipment that combines physical and chemical treatment processes, and is mainly used to improve the efficiency of water purification. It integrates multiple steps such as coagulation, flocculation, sedimentation and biochemical treatment to achieve efficient water treatment effects in a compact space.

2. working principle

1. Coagulation stage: Coagulation is an important link in the water treatment process, which aims to make the fine suspended particles in the water unstable and aggregate into larger flocs through chemical additives (coagulants). When raw water enters the equipment, it is first injected with a specific type of coagulant, such as polyaluminum chloride (PAC) or ferric sulfate, which reduces the charge repulsion between particles and makes it easier for them to clump together. In the coagulation zone, the coagulant is fully mixed with water through strong stirring to promote the aggregation of suspended particles.

2. Flocculation stage: After coagulation, the tiny flocs formed in the water need to be further combined to form larger flocs to facilitate the subsequent precipitation process. In the flocculation stage, by slowing down the stirring intensity and adjusting the water flow conditions, the small flocs have the opportunity to collide with each other and bond into larger flocs. This process is usually carried out in the flocculation reaction zone of the equipment, which is designed to slow down the water flow speed, which is conducive to the further growth of flocs.

3. Inclined tube sedimentation stage: The inclined tube sedimentation zone is the core part of the inclined tube sedimentation flocculation biochemical integrated machine. It uses inclined pipes (inclined tubes) to increase the sedimentation area, thereby improving the sedimentation efficiency. The large floc formed slides down the inclined tube under the action of gravity, while the clear water rises along the inclined tube. The inclined tube design increases the sedimentation area and reduces the distance the particles settle, so suspended solids in the water can be removed faster.

4. Biochemical treatment stage: After the precipitation is completed, the water is passed into a biochemical treatment zone, which is usually equipped with a biological filter or a biofilm system. Microorganisms attached to the filter or biofilm, they can decompose the organic matter in the water, such as ammonia nitrogen, nitrate, etc., so as to further improve the water quality. Biochemical treatment can not only remove the remaining trace organic matter, but also improve the biodegradability of water.

5. Sludge treatment and water clarification stage: The sludge accumulated at the bottom of the sedimentation zone needs to be discharged regularly to prevent the sludge from being suspended and decomposed again. The discharged sludge may be subjected to further treatment or disposal. After the above stages of treatment, the final product is clear upper water, which has greatly removed suspended solids and organic matter, and the water quality has been significantly improved.

3. Application Areas

Industrial wastewater treatment: The wastewater produced in the industrial field usually contains a variety of pollutants, including heavy metals, organic matter, suspended solids, etc. The use of inclined tube precipitation flocculation biochemical integrated machine can effectively remove these pollutants, especially in electroplating, coal mine, printing and dyeing, leather and other industries.

2. Drinking water treatment: In drinking water treatment, the equipment can be used to remove suspended solids, chromaticity and microorganisms in the water to ensure water quality safety.

3. Groundwater and surface water treatment: For micro-polluted groundwater and surface water, the treatment of this equipment can effectively improve water quality and remove suspended solids and some organic matter.

Features and advantages of 4. technology

1. High efficiency: The integrated design brings a significant increase in processing efficiency, which can remove a large amount of suspended solids and some soluble pollutants in a relatively short time.

2. Province of land: Compared with the traditional step-by-step processing, the all-in-one machine covers a smaller area and is suitable for use in places with limited space.

Low investment and operating costs: Due to the high degree of equipment integration, construction and maintenance costs are relatively low.

4. Easy operation: high degree of automation, simple operation and maintenance, easy to manage and control.
