example 1

[0048] use Figure 4 The sludge treatment plant shown in the figure treats sludge according to the following operating conditions:

[0049] First, in the pretreatment device, the pH value of the sludge is adjusted to 6.7-7.02, the temperature in the vertical reaction tower is 170-270 degrees, and the pressure is 20-25 atmospheres.

[0050] When the sludge and water treated in the tower are discharged, there is a lot of heat. The water and gas incidental to the heat pass through the return pipe and enter the tower for recycling. The return cycle process is continuous and controllable.

[0051] The components before sludge treatment contain: water content above 90%, parasites, germs, heavy metals Ni, Cd, Pb, Zn, Cu, Cr, As and other ions.

[0052] After sludge treatment, the composition contains: water content below 40%, no parasites and germs, heavy metal Ni, Cd, Pb, Zn, Cu, Cr, As and other ions form salts or form pure substances in line with national discharge standards.

Abstract

The present invention provides a sludge treatment device, which includes a tower body, a first feeding port, a second feeding port, a first discharging port and a second discharging port, wherein a reaction chamber is limited in the tower body; the first feeding port is located on the tower body and is used for supplying the sludge to be treated for the reaction chamber; the second feeding port is located on the tower body and is used for supplying steam for the reaction chamber; the first discharging port is located on the tower body and is used for discharging the treated sludge from the reaction chamber; the second discharging port is located on the tower body and is used for discharging steam from the reaction chamber; and the first feeding port is higher than the second feeding port.The present invention also provides a sludge treatment method using the sludge treatment device. The sludge treatment device and sludge treatment method using the same can effectively treat sludge.

Description

technical field [0001] The invention relates to the field of environmental protection. More specifically, it relates to a sludge treatment device and a sludge treatment method using the sludge treatment device. Background technique [0002] At present, different technologies such as thermal drying, hydrolysis, and incineration are used in sludge treatment technologies at home and abroad, but the main problems faced are high energy consumption and poor elimination of odors.
