Embodiment 1

[0034] Embodiment one, a kind of ship-borne method utilizing sludge to manufacture organic fertilizer co-production antibacterial building materials, comprises the following steps:

[0035] Step 1. Investigation: After on-site investigation, the water depth is 3 meters, and the sludge is 1 meter thick. The sludge contains 30% organic matter, 69% mud and sand, and 1% of heavy metals are mainly chromium, iron, and chromium, and the reserves are 50 million Tons, a large amount of permeable bricks are needed for the construction of a wetland park in this area, and watermelon and tobacco are mainly planted in rural areas;

[0036] Step 2. Design: According to the data obtained in Step 1, it is determined that the ship is designed to have a draft of 1.8 meters and a load capacity of 3,000 tons (with a deck area of ​​1,500 square meters). The mud is directly taken from the bottom of the water with a bucket. After dehydration and separation, the organic matter is passed through Dehydr...

Embodiment 2

[0050] Embodiment two, a kind of ship-borne method utilizing sludge to manufacture organic fertilizer co-production antibacterial building materials, comprises the following steps:

[0051] Step 1. Survey: After on-site survey, the water depth here is 8 meters, and the sludge thickness is 2 meters. Among them, the sludge contains 10 million tons of organic matter, and the annual production is nearly 1 million tons. Raw materials are scarce, and the main crops are flowers and rice;

[0052] Step 2. Design: According to the data obtained in Step 1, it is determined that the ship is designed with a draft of 3 meters and a load capacity of 5,000 tons (with a deck area of ​​6,000 square meters). The mud is taken from the bottom of the water with a bucket. After dehydration and separation, the organic matter is passed through Fermentation after dehydration to produce special fertilizers for flowers and rice, and mud and sand to produce building blocks or antibacterial decorative pan...

Abstract

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.

Description

technical field [0001] The invention relates to a ship-borne method for using sludge to manufacture organic fertilizer and co-produce antibacterial building materials, which belongs to the fields of environmental protection, soil fertilizer and building materials. Background technique [0002] The traditional and current common practice is to find a low-lying place to bury the sludge from the sewage treatment plant and the sludge salvaged from the lake. However, due to the large water content and harmful heavy metals, it becomes a waste water with the leaching of rainwater. Non-point source pollution. Some people also try to transport it to the field as an organic fertilizer, but the high water content, low active ingredients and the risk of excessive heavy metals are already daunting; some people try to solidify and then landfill, but due to high water content and more organic matter, The curing cost is higher, and it is difficult to be suitable for marketization. [0003...
