Embodiment 1

[0026] Such as figure 1 As shown, a high-speed sludge treatment system, the system includes a sludge tank 1, and the sludge delivery pump 2 arranged in the sludge tank 1 is transported to the sludge mixing tank 3 through a pipeline, and the sludge mixing tank 3 passes the sludge The mud input port 4 is connected to a sludge filter press 5 provided with a filtrate outlet 6 for delivering the filtrate to a filtrate pool 9 and a mud cake outlet 7 for discharging the mud cake.

Embodiment 2

[0028] On the basis of Embodiment 1, the sludge agitation tank 3 in this embodiment is provided with a return pipe 13 leading to the sludge tank 1 . When the sludge pumped into the mixing tank exceeds the limit, the excess can flow back to the sludge tank through the return pipe.

Embodiment 3

[0030] On the basis of Embodiment 1 or 2, the system described in this embodiment is provided with flocculant addition equipment leading to the sludge stirring tank 3, including a flocculant addition pump 11, a flocculant injection port 10 and corresponding pipelines; corresponding sludge A mixing and stirring device 12 is arranged in the stirring tank 3 . After adding flocculant to the sludge mixing tank, the particles in the sludge can be concentrated, which is convenient for the next step of treatment.

Abstract

The invention discloses a high-speed sludge treating system, comprising a sludge pool, a sludge delivery pump, a sludge stirring tank, a sludge filter press and a filtrate pool, wherein the sludge delivery pump is arranged in the sludge pool and used for delivering sludge to the sludge stirring tank via a pipeline, the sludge stirring tank is connected with the sludge filter press via a sludge input, and the sludge filter press is provided with a filtrate outlet used for delivering filtrate to the filtrate pool and with a sludge cake outlet used for discharging a sludge cake. The high-speed sludge treating system is reasonable in structural design and convenient to use, can continuously and highly efficiently carry out sludge treatment and is applicable to a large water plant or sludge treatment unit.

Description

technical field [0001] The invention relates to the field of environmental protection and purification, in particular to a high-speed sludge treatment system. Background technique [0002] Sludge is an inevitable product of sewage treatment in sewage treatment plants and sewage stations. Untreated sludge entering the environment will directly bring secondary pollution to water bodies and the atmosphere, and it will also affect the ecological environment and human activities. would pose a serious threat. Therefore, the treatment of sludge is very cautious, and the treatment of sludge can be divided into two types: sludge dehydration process and sludge drying process. [0003] There are roughly three types of sludge in sewage treatment plants: physical-chemical sludge, biochemical sludge, and physical-chemical-biochemical mixed sludge. [0004] According to different treatment environments, the commonly used equipment is centrifugal: all three kinds of sludge can be used, bu...
