Kitchen Waste Wastewater Treatment Chemicals
Food waste wastewater treatment is a complex process that involves the use of a variety of chemicals, aiming to remove organic matter, grease, suspended solids, etc. from the wastewater. The following is an overview of food waste wastewater treatment chemicals.
1. Characteristics of food waste wastewater
Food waste wastewater usually has the characteristics of high organic matter content, high grease content, high salt content and complex components. These characteristics make the treatment of food waste wastewater more difficult, and appropriate chemicals and processes need to be used for treatment.
2. Pretreatment chemicals
Demulsifier: used to break the emulsion in wastewater and separate oil and water. Commonly used demulsifiers include inorganic salts, organic acids and polymer compounds.
Acidifier: used to adjust the pH value of wastewater and improve the efficiency of subsequent treatment. Commonly used acidifying agents include sulfuric acid, hydrochloric acid, etc.
3. Biochemical treatment agents
Nutrient salts: Provide necessary nutrients for microorganisms, such as nitrogen, phosphorus, etc., to promote biochemical reactions.
Biological enzymes: accelerate the decomposition and transformation of organic matter and improve the efficiency of biochemical treatment.
pH regulator: used to maintain a stable pH value in the biochemical reaction pool and ensure the normal growth and metabolism of microorganisms.
4. Deep treatment chemicals
Adsorbents: such as activated carbon, diatomaceous earth, etc., used to remove residual organic matter and odor in wastewater.
Oxidants: such as ozone, hydrogen peroxide, etc., are used to further oxidize and decompose organic matter and improve the quality of effluent water.
Membrane treatment agents: Agents used in the membrane separation process, such as scale inhibitors, bactericides, etc., to protect the normal operation of membrane components.
5. Precautions for drug selection and use
Agent selection: Appropriate agents should be selected based on the characteristics, treatment technology and effluent requirements of food waste wastewater. At the same time, the cost of the medication should be considered.
Dosage of chemicals: Excessive dosage of chemicals will not only increase treatment costs, but may also have adverse effects on the environment and microorganisms. Therefore, the optimal dosage of pharmaceuticals should be determined through small experiments.
Agent mixing and reaction: Ensure that the agent and wastewater are fully mixed, and allow sufficient reaction time to achieve better treatment results.
Medicament storage and management: Medicaments should be stored in a dry, cool, ventilated place, away from direct sunlight and high temperatures. At the same time, medications should be inspected and replaced regularly to ensure their quality and effectiveness.
In summary, the selection and use of food waste wastewater treatment chemicals is a complex and important process. In practical applications, the type and dosage of chemicals should be flexibly adjusted according to specific conditions to achieve better treatment results.
