example 1

[0048] use Figure 4 The sludge treatment plant shown, 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 attached 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: more than 90% water content, parasites, germs, heavy metals Ni, Cd, Pb, Zn, Cu, Cr, As and other ions.

[0052] The components after sludge treatment contain: water content below 40%, no parasites and bacteria, heavy metals Ni, Cd, Pb, Zn, Cu, Cr, As and other ions to form salts or pure substances that meet the national emission standards.

[0053] The e...
