Embodiment 1
[0017] A sludge treatment method mainly comprises the following steps,
[0018] 1) Screening, washing the sludge with water, and passing the formed slurry through a 400-mesh sieve to remove large particles of impurities and other substances;
[0019] 2) Precipitation, the mud after sieving and separation is left to stand for 2 days, and the mud and water are separated;
[0020] 3) remove water, remove the water formed after precipitation;
[0021] 4) pressure filtration, the sediment is squeezed by mechanical pressure filtration and filter membrane to remove water;
[0022] 5) Disinfection, the sediment after pressing is disinfected with limestone;
[0023] With the above steps, the sludge can be effectively treated.
Embodiment 2
[0025] A sludge treatment method mainly comprises the following steps,
[0026] 1) Screening, washing the sludge with water, and passing the formed slurry through a 500-mesh sieve to remove large particles of impurities and other substances;
[0027] 2) Precipitation, the mud separated by sieving is left to stand for 4 days, and the mud and water are separated;
[0028] 3) remove water, remove the water formed after precipitation;
[0029] 4) pressure filtration, the sediment is squeezed by mechanical pressure filtration and filter membrane to remove water;
[0030] 5) disinfection, the sediment after pressing is disinfected with calcium hypochlorite;
[0031] With the above steps, the sludge can be effectively treated.
Embodiment 3
[0033] A sludge treatment method mainly comprises the following steps,
[0034] 1) Screening, washing the sludge with water, and passing the formed slurry through a 450 mesh sieve to remove large particles of impurities and other substances;
[0035] 2) Precipitation, the mud after sieving and separation is left to stand for 3 days, and the mud and water are separated;
[0036] 3) remove water, remove the water formed after precipitation;
[0037] 4) pressure filtration, the sediment is squeezed by mechanical pressure filtration and filter membrane to remove water;
[0038] 5) Disinfection, the precipitate after pressing is disinfected with a mixture of calcium hypochlorite and limestone;
[0039] With the above steps, the sludge can be effectively treated.
