The concrete mixing station will discharge some industrial wastewater during the production process. If discharged indiscriminately, it will cause serious pollution to the surrounding environment and may contaminate nearby water sources, affecting the water supply for nearby residents. Therefore, the treatment of wastewater discharged from the mixing station must also follow certain requirements.
1. Wastewater, waste oil, and domestic sewage generated by construction machinery and equipment at the concrete mixing station must not be directly discharged into rivers, lakes, or other water bodies, nor into land near drinking water sources. Based on the site conditions of the concrete mixing station, reasonable layouts should be made to build wastewater sedimentation tanks and vehicle washing pools, establish drainage systems, and set up clear signs; reasonable tertiary or higher filtration pools should be set up for wastewater discharge. The wastewater discharge plan needs to be designed and planned, with multi-stage sedimentation tanks set up to achieve discharge standards through sedimentation and filtration. Toilet sewage should enter the septic tank through a centralized independent pipeline for closed treatment.
2. A large garbage accumulation pool should be set up in both the living area and the office production area of the concrete mixing station to concentrate various types of garbage. The garbage disposal pool is generally constructed of bricks, with a volume of no less than 4m×3m×1.5m. Collaborate with local environmental protection departments to dispose of construction waste left after production by local sanitation departments. The ground should be regularly watered, and during hot weather such as summer, it should be watered daily to reduce dust and temperature, maximizing coverage of dust sources.
3. After each concrete mixing operation at the concrete mixing station is completed, the machinery should be cleaned promptly, and the site should be cleared to maintain cleanliness.
4. Vehicle and equipment washing facilities, drainage ditches, and sedimentation tanks should be set up as needed. Construction wastewater can only be discharged into the municipal sewage network or rivers after treatment meets standards.
Achieving reasonable wastewater discharge not only contributes to the national economic construction but also better promotes the concrete mixing station's development towards energy conservation and environmental protection.
