Analysis and utilization of waste pulp wastewater performance of concrete mixing plant

Ready-mixed concrete production process will consume large amounts of water, whether it be concrete mixer trucks, or a pump, cleaning is required every time you work came to an end, will produce a lot of waste waste pulp. If these waste slurry direct discharge of waste water will be some burden on urban drainage pipe network, while alkaline substances in waste pulp wastewater on the surrounding soil, causing serious pollution in water bodies. According to the information reported, each producing 1 cubic metres of concrete will require clean water 0.17 tonnes, wastewater is produced on average 0.03 tons of waste pulp. Incomplete statistics according to the concrete network, 2013 yield 2.196 billion cubic metres of ready-mix concrete in China, preliminary, and clean water for 370 million tons of water to be consumed, resulting in waste pulp 65 million tons of waste water. If 65 million tons of waste water waste slurry was used, current water price 5 Yuan per ton in Beijing estimates that will save money for the State each year more than 300 million Yuan. Therefore, waste pulp wastewater recycling, to protect both the environment green production, ready-mixed concrete enterprise can also save the cost of production. How to improve water utilization of waste pulp, waste pulp wastewater zero discharge, is a ready-mixed concrete production enterprises is urgently needed to address important issues.
