What are the common facilities for acid-base neutralization method
(1) Neutralization facilities for acid-base wastewater
① When there is little change in water quality and quantity, or when the buffering capacity of wastewater is large, or when subsequent structures require a wide range of pH values, it is not necessary to set up a separate neutralization tank. Instead, continuous flow mixing and reaction can be carried out in a collection well, pipeline, or meandering mixing tank.
② When there is little change in water quality and quantity, and the wastewater has a certain buffering capacity, but in order to ensure the pH value of the effluent, a separate continuous flow neutralization tank should be set up.
③ When the water quality and quantity change greatly and the water quantity is small, the continuous flow neutralization tank cannot guarantee the required pH value of the effluent, or the effluent quality requirements are high, or the wastewater still contains other impurities or heavy metal ions. A more reliable approach is to adopt an intermittent neutralization tank. At this time, there should be at least two neutralization tanks for alternating use, and the volume of each tank can be calculated based on the amount of wastewater discharged per shift or day and night.
(2) Drug neutralization treatment equipment and facilities
① There are two ways to add neutralizing agents: dry and wet. The equipment used and the method of adding coagulants are the same.

② The mixed reaction tank is generally a partition type mixed reaction tank, which uses compressed air or mechanical stirring inside the tank. The sedimentation tank is mostly a horizontal flow sedimentation tank.
(3) Filtering and neutralization facilities. There are two types of filtration and neutralization facilities: gravity based ordinary neutralization filter and upward flow expansion filter.

acid-base neutralization

Due to the presence of acids, alkalis, and inorganic salts in wastewater, acid-base neutralization treatment is required. In the acid-base neutralization tank, a pH controller is used to accurately add a certain amount of NaOH aqueous solution using a metering pump, adjusting the pH value to between 8-9. Under alkaline conditions, the acid in the wastewater is neutralized, and heavy metal ions such as iron, cadmium, copper, manganese, nickel, lead, and chromium react chemically with OH - to form hydroxide precipitates.

In addition, corn has been sporadically launched in Sichuan and Guangxi recently, and new corn from Hubei will also be launched in late July and early August. However, considering that the above-mentioned corn does not have an advantage in quality, the launch of new grain in China's high-quality corn producing areas will still have to wait until after October. Therefore, the summer market may see a return of the price difference between high-quality corn and ordinary corn after the bottom of grain prices. Moreover, in the context of the escalating Sino US trade war, the obstruction of imported grains will indirectly boost the corn market in the near future.

sedimentation tank

After being treated with acid-base neutralization, the sewage partially dissolves and forms a precipitate. This precipitate, along with the original suspension in the sewage, is separated into mud and water in the sedimentation tank, fully achieving mud and water separation and ensuring that the suspended solids index meets the standard.

oxidation pond

Due to the fact that the wastewater in this project is generated during testing and contains a certain amount of pathogenic microorganisms, this plan involves setting up an oxidation tank and adding ozone to kill the pathogenic microorganisms in the water.

Active adsorption device

After treatment, the wastewater enters the active adsorption device. Suspended solids, trace metals, and very small amounts of organic matter that have not been removed are partially removed through physical and chemical processes such as adsorption and interception. The other part is degraded and removed by anaerobic, aerobic, and facultative bacteria in the microbial membrane attached to the filter material. Activated carbon is intercepted and adsorbed, and combined with microorganisms.

The harmful microorganisms contained in wastewater, including domestic wastewater, leather wastewater, and wastewater, all contain a considerable number of harmful microorganisms such as pathogens, bacteria, and parasitic insect eggs. They can cause organic matter and odor in water, and are the main culprits causing water quality deterioration. It can also cause diseases to humans, animals, and plants, affecting health and normal life activities, and in severe cases, can lead to death. Especially under the current conditions of ecological deterioration on Earth, it has provided suitable habitats for harmful microorganisms and facilitated their spread. The entire Earth, especially water ecology, is controlled by harmful microorganisms, which is the root cause of ecological deterioration in water bodies.
