Commercial concrete mixing plant must pass the EIA test during construction, but many customers find that the commercial concrete mixing plant is not environmentally friendly after it is built. What should we do?
1. Upgrade the existing commercial concrete mixing plant, turn the old-fashioned open-air working mode into a closed working process, and adopt the building method requiring all the aggregates and equipment to be sealed.
2. Plant greenbelt, planting irrigation, trees, etc. In the commercial concrete mixing plant area, select low-noise equipment, optimize the site setting, keeping high-noise equipment away from residents, adding noise reduction measures to major noise-making equipment, and strengthening vibration reduction treatment of equipments, and minimize night construction work to prevent disturbances.
3. The commercial concrete mixing plant should use a dust collector with good dust removal effect. The aggregate of sand and gravel is covered with a net. If there is soil and garbage, the soil will be backfilled to keep the structure clean and tidy. Construction site should be isolated by fences, the buildings are covered with high fences to keep urban civilization. And the safety of passing pedestrians will be guaranteed. Concrete trucks shall be washed before leaving factory, sprinklers can be used at the periphery of the building, and sprinklers shall be used in the factory regularly.
4.Set up a construction wastewater sedimentation tank at the construction site, and reuse the clean water after sedimentation. The wastewater shall be in accordance with the principle of “cleaning and diverting”. After the wastewater of leaning equipment and washing site is collected and treated by the third-stage sedimentation tank, the water can be reused.And the sludge can be periodically cleaned and used as aggregate.
