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.
