It provides supporting services for agriculture, energy, transportation, machinery, electronics, textiles, light industry, construction, building materials and other industries and people's daily life. It occupies a pivotal position in the national economy. Wastewater refers to the general term for water discharged during petrochemical operations and runoff rainwater. It includes domestic sewage, industrial wastewater and other unused water such as initial rain runoff into drainage pipes. It generally refers to water that cannot be recycled after certain technical treatment or water that cannot meet certain standards for purification after primary pollution. When conducting petrochemical production, wastewater treatment institutions are required to filter sewage.
