Introduction to Special Terminology for Water Treatment Resources of Sludge Tank Mixer

The beneficial utilization of submersible mixers: There are many ways in which water can be utilized, such as for drinking water or for other purposes to obtain overall benefits, such as municipal water supply, agricultural and industrial water use, aviation, fisheries and ecological water use, habitat improvement and water and accessible recreational water use.

Submersible mixer is supplied with water: water that is transferred from one hydrological area to another hydrological area, such as the California Water Transfer Project. Colorado River Project.

Comprehensive utilization planning of water resources for submersible mixers: a process of promoting coordinated development and management of water, land, and related industries, in a fair manner, to achieve maximum economic and social wealth under sustainable development conditions.

Water reuse in submersible mixers: Water resources are reused in various fields, but not including direct or indirect drinking reuse.

Planning water reuse for submersible mixers: utilizing reclaimed water directly or indirectly in a planned manner, including controlling the water transportation process.

Submersible mixer for drinking and reuse(Direct): The highly treated water is directly discharged into the drinking water supply distribution system of the game under the water treatment plant, or the water is immediately mixed into the source water supply system upstream of the water treatment plant.

Submersible mixer for drinking and reuse(Indirect): Planned mixing of reclaimed water with source water for main use, such as discharging reclaimed water into drinking water storage tanks or injecting it into groundwater aquifers, to assimilate the reclaimed water with the source water for reuse.

Submersible mixer regenerated water(or circulating water): Municipal sewage, after undergoing different treatment processes, meets the prescribed water quality standards and can be effectively utilized.

Submersible mixer sewer mining: Collect wastewater from the sewage main pipe and then enter the satellite treatment plant for treatment, in order to achieve the purpose of wastewater reuse.

Regulations on Submersible BlendersTITLE22： The California regulations on how to handle and recycle water are listed in California Administrative Condition TITLE22. The interstate water cycle standards are developed by the Department of Health Services and implemented by nine California regional water quality control treatments.

Submersible mixer wastewater regeneration: After treating the wastewater, achieve good treatment effect and water quality indicators.

Submersible mixer wastewater recycling: Collect wastewater and directly reuse it in the same water usage scheme, such as industrial wastewater recyclingThe recycling of recycled water is generally carried out simultaneously with the reuse of wastewater.

Reuse of submersible mixer wastewater: The wastewater is treated and reused, such as for agricultural irrigation and industrial cooling.

Due to factors such as the continuous increase in population, worsening pollution of surface and groundwater, imbalanced distribution of water resources, and periodic droughts, some water resource institutions have to seek additional ways to obtain water sources. The reuse of secondary effluent will be an important strategic plan for future water resource management.

Principle and Equipment Design of Push Flow Submersible Blender

Du'an Environmental Protection Sludge MixerIt is the use of highly dispersed microbubbles as carriers to adhere pollutants in wastewater, making their density lower than that of floating on the water surface, thus achieving solidification-The process of liquid-liquid separation. In sewage treatment, submersible mixers are widely used to treat wastewater containing small floating particles, algae, and micro flocs, papermaking wastewater, and oily wastewater. According to the different ways of generating microbubbles, their gas submersible mixers are divided into electrolytic submersible mixers, submersible mixers, dissolved gas submersible mixers, biochemical submersible mixers, and ion submersible mixers.

The basic principle of submersible mixer separation is to introduce air into the sewage, which generates a large number of fine bubbles in the sewage and promotes their adhesion to impurity particles, forming a submersible mixer with a density lower than water. Under the action of the submersible mixer, solid particles are achieved-Liquid or liquid-liquid separation.

The contact adsorption mechanism between microbubbles and particles usually has two situations: one is the presence of microbubbles in the middle of the floc, and the larger the floc, the stronger this tendency, which can better retain the bubbles. The second is the adsorption of bubbles and particles, which is caused by the interfacial tension between the two phases. According to the action on gas-solid-The interfacial tension between the liquid and three-phase phases can be used to infer the magnitude of this adsorption force. At the three-phase contact point, the o-contact formed by the gas-liquid interface and the solid-liquid interface is called a contact point.

The selection of a push flow submersible mixer is a complex taskThe correctness of the selection directly affects the normal use of the equipment,Nanjing Du'an Water Treatment believes that the principle of selection is to ensure that the mixer produces a completely suitable volume mixing functionThe available speed is usually determined. According to different process requirements of sewage treatment plants, the mixer should ensure the best speed between 0.15 and 0.3 meters per second. If the speed is less than 0.15 meters per second, it is a short push flow mixing effect. If the speed exceeds 0.3 meters per second, it will affect the effect and cause waste. Firstly, determine the location selected for the QJB mixer before use, such as sewage tank, sludge tank, and biochemical tank; Next are the parameters of the medium, such as suspended solids content, viscosity, temperature, pH value, pool shape, water depth, etc.

The volume, size, and density of the liquid required for the matching power of the submersible mixerDetermine the mixing depth and mix with one or more mixers depending on the specific situation.

Purpose and applicable conditions of submersible mixer

The hybrid series submersible mixer is suitable for various water treatment and industrial processes that require solid, solid, liquid, gas-liquid two-phase or three-phase mixed reaction media.

QJB submersible mixer installation system

The specialized installation system of QJB submersible mixer can quickly install and disassemble the submersible mixer without the need to discharge sewage from the pool. When the pool depth H is less than 4 meters, it is recommended to use installation system I. The diving depth of the submersible mixer can be adjusted vertically as needed, and the maximum angle that can rotate around the guide rod in the horizontal plane is ± 60 °. The lifting system base, support frame, and lower bracket are all fixed with expansion bolts at the associated interface with the pool, without the need for reserved holes. When the pool depth H is greater than 4 meters, it is recommended to use installation system II, which requires a concrete foundation (or steel structure base) to be built at the bottom of the pool. The lifting system base, steel rope fixing frame, and guide base are all fixed with expansion bolts at the associated interface with the pool, without the need for reserved holes. The installation system II uses guide steel ropes instead of guide rods, which has the characteristics of convenient transportation and simple on-site installation. This system fundamentally avoids the situation of guide rod bending and deformation caused by transportation, which affects normal use, and effectively improves the phenomenon of inability to lift due to installation errors of guide rods when the pool is too deep. Under the installation conditions with a cantilevered pool roof (as shown in the picture), it appears more convenient and reliable to operate. When the customer places an order, please provide the pool depth H and pool type diagram so that the factory can determine the size of the guide rod or guide wire during processing. The material of the installation system is made of stainless steel (or carbon steel). In addition to guide rods or guide wires, and lifting bases, multiple mixers can share a set of lifting devices in the installation system (except for special user requirements).

Performance characteristics of QJB submersible mixer

The QJB submersible mixer is mainly composed of submersible motor, sealing mechanism, impeller, guide cover, hand hoist, electrical control and other parts. The stirring impeller rotates and stirs the liquid under the drive of the motor, generating a rotating jet and using the shear stress along the jet surface to mix. The liquid outside the flow field is stirred by friction, forming a volumetric flow while extremely mixing. The controlled fluid transport is achieved by applying a large volume flow mode.
