Shipborne method for preparing organic fertilizer and coproducing antibacterial building material by utilizing sludge
The invention relates to a shipborne method for preparing an organic fertilizer and coproducing an antibacterial building material by using sludge. The method comprises the following steps: exploring,designing and sucking sludge, carrying out primary solid-liquid separation to lower the water content to 80% or below, stirring, carrying out air floatation to separate heavy metals, organic mattersand mud sand, sucking the organic matters from the upper layer of a separation tank, and carrying out fermentation compounding to obtain the organic fertilizer. The silt sediment is dehydrated for thesecond time to enable the water content to reach 20%-50%, the special cementing material is added according to 5%-30% of the silt dry basis, and the building block, the water permeable brick and thebuilding antibacterial building material with the antibacterial function can be obtained through stirring and forming. According to the technical method, land acquisition is not needed, secondary pollution is avoided, the method is environmentally friendly, the developed antibacterial veneer board is particularly suitable for public places of high-risk groups and sterile wards, food factories, pharmaceutical factories and high-end residences of the public places in a wide range, and good news is brought to health of people.
一种船载的利用污泥制造有机肥联产抗菌建材的方法，通过勘察、设计、吸取污泥，经过第一次固液分离使得水分下降至80%以下，然后搅拌气浮分离重金属、有机质和泥砂，将有机物从分离罐上层吸取后发酵复配即成有机肥；而泥砂沉淀经第二次脱水使水分达20%‑50%，将专用胶凝材料按泥砂干基的5%‑30%配入，经搅拌成型可以获得砌块、透水砖及其具有抗菌功能的建筑抗菌建材。本技术方法不用征地不造成二次污染，而且环境友好，特别是开发的抗菌饰面板材广范地适用于高危人群的公共场所及其无菌病房、食品厂、药厂及高端住所，为人们的健康带来了福音。
