The selection of sludge dewatering machine needs to be based on the drug inclined plate sedimentation tank before sludge separation can be completed. The commonly used coagulant is anionic (cationic) cationic flocculant (PAM), which has a clear adsorption and railway bridge effect in its molecular structure. The molecular structure chain is long, and it touches the floating particles in wastewater. The floating particles are adsorbed around the molecular structure chain, and have a railway bridge effect between the floating particles, creating a porous structure that causes the fine floating particles to aggregate into a large inclined plate sedimentation tank, thereby improving the actual effect of suspended solid deposition and sludge treatment characteristics.

What is the basic principle of wastewater homogenization adjustment?

The flow rate and water quality of wastewater discharged from daily life by manufacturing enterprises or households are constantly changing over time, including peak total flow and low peak total flow, as well as peak concentration values and low peak concentration values. The uneven distribution of total flow rate and concentration values often creates many difficulties for processing equipment or makes it difficult to maintain operation under optimized processing standards; Or make it unable to work for a short period of time, and even suffer damage. In order to better improve the working standards of wastewater treatment equipment, it is necessary to carry out equalization and adjustment of water flow and quality. The building selected for homogeneous adjustment in sewage treatment plants is called a regulating tank.

There are generally three types of regulating pools.

(1) The general rule for water flow regulation pools is to only adjust the water flow, simply set up a simple reservoir, maintain the necessary regulation pool capacity, and apply water evenly. Like the suction reservoir in front of the sewage treatment plant.

(2) The water quality control tank adopts the following measures in terms of structure and function to achieve uniform wastewater quality.

① Perforated drainage trough type regulating pool. The wastewater that enters the regulating tank separately is mixed with the wastewater that enters the regulating tank from the front, back, left, and right sides due to the different step lengths, in order to balance the water quality.

② Improve the mixing machinery. Gas mixing, mechanical mixing, and hydraulic engineering mixing can be added to the regulating tank.

(3) If there is a regular impact load such as leakage or accidents during the production process, setting up an accident regulation pool can separate and store water. After the accident is resolved, the accident wastewater will be discharged at a small total flow rate to maintain and solve the system software from being impacted.

What is the basic production process of wastewater treatment equipment? Based on the flow rate and water quality of wastewater, the production process of Zhonghe equipment should basically have homogeneous reflection tanks, mixed reflection tanks, sedimentation tanks, and sludge treatment equipment.
