Is the pH value still unstable after pickling wastewater treatment?

Turn down the setting parameters of the pH instrument.

Acid and alkali wastewater is first recommended for reuse treatment.

For high-concentration acid and alkali wastewater, it can be reused, and for low-concentration acid and alkali wastewater, such as the cleaning water of the pickling tank, the rinsing water of the alkali washing tank should be neutralized before being discharged. If there is a lack of corresponding facility conditions, neutralizer wastewater treatment can also be used.

Acid and alkali wastewater has the characteristics of strong acid and strong alkali, and has high corrosiveness, if you want to carry out acid and alkali wastewater treatment, it is best to develop a detailed treatment process. It is recommended to consult with a professional environmental protection engineering company, which can effectively avoid the waste of time and cost, and the acid and alkali wastewater treatment process and design can refer to the project engineering case of Lezhong Environmental Protection.

Summary. Hello dear! The pH value of sewage treatment is generally between 7 and 8, and because sewage may contain organic matter and metal ions, precipitate is formed when the pH value is high, which will make the sewage difficult to clear.

In addition, denitrification can change the quality of the effluent, making it less clear.

Hello dear! The pH value of sewage treatment is generally between 7 and 8, because the sewage may contain organic matter and metal adstrapping ions, and the precipitation will be formed when the pH value is high, which will make the sewage not easy to clear. In addition, denitrification operations may also change the quality of the sewage, making it difficult to clear the sewage.

The pH value of sewage treatment is in the range of 7 8, which is a standard requirement for sewage treatment measures. However, if the pH value is outside the range of 7 or 8, the effluent will be turbid, which will affect the treatment effect. Therefore, if there are a large amount of calcium, phosphorus, sulfate and other organic substances in the water body, these organic substances in the mountain will affect the pH value and make it exceed the standard range of 7 8.

In addition, in sewage treatment, when the pH value is lower than 7, the condensation of organic matter will be weakened, making the effluent turbid; When the pH value exceeds 8, the motif that has undergone organic adsorption forms a molecular complex in the organic molecule, which affects the extraction of the organic matter, and the organic matter is also easy to flow out with the water, thus aggravating the turbidity and causing the water to be turbid and unclear.

The pH value of sewage treatment is incorrect, under normal circumstances, the pH value of sewage treatment should be between, 7-8 is too high, in this case, the water from sewage treatment will be turbid and not clear. If the pH value is too high, it will lead to poor treatment effect, which may hinder the oxidation of organic matter, so that organic matter can still be photographed in the water, resulting in turbidity and clarity of sewage effluent. If the pH value is too high, it may also cause the suspended solids, sediments and organic matter in the sewage to combine to form sediments, which can also cause the effluent to be turbid and unclear.

Too high a pH level may also affect the biological activity of the wastewater treatment process and affect the ability to remove organic matter, resulting in turbidity and clarity of the effluent.

Hello, industrial wastewater pH 9 is degraded with alkali. The acidic substances contained in industrial wastewater are usually discharged up to the standard by adding alkaline substances (lime, caustic soda, etc.) and adjusting the pH value to the range of 6-9. However, general acidic wastewater cannot exist alone, and if it exists alone, without interference from other substances, it can be used as a resource.

Generally, acidic wastewater is more abundant in the metallurgical industry, and many metals need to be extracted with acids. This type of wastewater is commonly known as acid wastewater. Generally, the pH value is adjusted to alkalinity, and then it can be treated by electrochemistry, membrane process, iron salt method, vulcanization method and other technical means to achieve the standard.

Summary. Hydrolysis acidification tank treatment wastewater, COD is reduced, PH does not drop What is the reason, COD degradation in sewage has the following situations: (1) activated sludge with good biochemical properties can be degraded; (2) Poor biochemical properties can be reduced by physical and chemical methods; (3) The refractory ones can be reduced by advanced oxidation methods; (4) If the water quality is complex, the above three methods can be organically combined to obtain the optimal method.

Hydrolysis acidification tank treats wastewater, COD decreases, PH does not drop what is the reason.

Hydrolysis acidification tank treatment wastewater, COD reduction, PH does not drop What is the reason, COD drop-base aerolysis in sewage has the following situations: (1) activated sludge with good biochemical properties can be degraded; (2) Poor biochemical properties can be reduced by physical and chemical methods; (3) The refractory ones can be reduced by advanced oxidation methods; (4) The water quality is complex, and the above three methods are organically combined to obtain the optimal method. Hope it helps.
