Reasonable Sewage Discharge of Concrete Batching Plant
Concrete batching plants will discharge some industrial wastewater during the production process. If discharged at will, it will cause serious pollution to the surrounding environment and may pollute the surrounding water sources, affecting the water use of nearby residents. Therefore, the treatment of wastewater discharged from concrete mixing plants must also follow certain requirements.
- Wastewater, waste oil and domestic sewage generated by construction machinery and equipment of concrete mixing plants shall not be discharged directly into rivers, lakes or other waters, nor into land near drinking water. According to the site conditions of the concrete mixing station, it is necessary to reasonably layout, build wastewater sedimentation tanks and car wash pools, lay out drainage systems, and set up obvious signs; set up reasonable three-level or above filtration tanks to discharge sewage. The sewage discharge plan needs to be planned and designed, and multi-stage sedimentation tanks need to be set up to meet the discharge standards through sedimentation and filtration. Toilet sewage enters the septic tank through centralized independent pipes and is treated in a closed manner.
- A large garbage accumulation pool should be set up in the living area and office production area of the concrete mixing station to store various garbage in a centralized manner. The garbage disposal pool is generally a brick structure with a volume of no less than 4m×3m×1.5m. Cooperate with the local environmental protection department, and the construction waste left after production will be handed over to the local sanitation department for disposal. The ground should be watered regularly, and in hot weather of summer, it should be watered every day to reduce dust and temperature, and to cover and block dust sources to the greatest extent possible.
- After each operation of the concrete batching plant is completed, the equipment must be cleaned in time and the site must be cleaned to keep the site tidy.
- Motor vehicle and equipment washing facilities, drainage ditches and sedimentation tanks should be set up as needed, and construction wastewater can only be discharged into the municipal sewage network or rivers after being treated to meet the standards.
Achieving reasonable discharge of sewage can not only contribute to the national economic construction, but also better promote the development of concrete mixing plants in the direction of energy conservation and environmental protection.
