直接用热干化或湿污水污泥制砖应予制止

Direct Hot Dry or Wet Sewage Sludge for Brick Making should be Stopped

直接用热干化污泥(或湿污泥)制砖,不符合安全环保、循环利用、节能降耗、稳妥可靠的原则,是典型的投资高、能耗高、运行费高而烧砖质量低的处置方案;特别是以甲烷为主的每吨湿污泥高达400～600kgCO_2当量的碳排放,既污染环境又浪费污泥70～80%的热值,应当制止。国标也应当尽快废除。

Direct hot dry sludge （ or wet sludge ） brick does not conform to safety and environmental protection, recycling, energy saving, safe and eliable principles, His atypical of high investment, high energy consumption, high peration cost and brick quality low solution; especially for methane mainly wet sludge high amounts to 400 per ton 600kgCO2 equivalent carbon emission, environment pollution and waste sludge calorific value of 70 - 80%, should stop. GB also should be abolished.
