All-in-one machine for sewage sludge treatment

Abstract

The invention relates to an all-in-one machine for sewage sludge treatment, and belongs to the technical field of environmental protection. The all-in-one machine comprises a sewage filtering tank, a clear water tank, a micro filter screen and a sludge pressing tank, wherein the sewage filtering tank is used for being communicated with the outside to store sewage; the clear water tank is arranged below the sewage filtering tank; the micro filter screen is arranged between the sewage filtering tank and the clear water tank, and used for filtering the suspended solids and the flocculating constituents in the sewage; the sludge pressing tank is arranged at one end of the micro filter screen to collect the suspended solids and the flocculating constituents on the micro filter screen; the micro filter screen is arranged on a transmission mechanism, and pushed to move circularly by the transmission mechanism; a pushing device used for pushing the suspended solids and the flocculating constituents in the sludge pressing tank to move is arranged in the sludge pressing tank; a concentrated liquid storing tank positioned at one end of the pushing device is arranged in the sludge pressing tank; a filter cylinder and a pressing plate arranged at the opening end of the filter cylinder are arranged in the concentrated liquid storing tank; the filter cylinder is connected with the pushing device; the suspended solids and the flocculating constituents in the sludge pressing tank are pushed into the filter cylinder by the pushing device.

Description

technical field [0001] The invention relates to an integrated sewage sludge treatment machine, which belongs to the technical field of environmental protection. Background technique [0002] With the development of economy and society, a large amount of water resources are needed every day. After living and production activities, the water becomes sewage. If the sewage is directly discharged into natural water bodies without treatment, it will destroy the natural water ecosystem. Therefore, how to deal with these sewage and protect the natural environment has been paid more and more attention by people. However, the current existing sewage treatment equipment has some problems and defects to varying degrees. [0003] The current traditional sewage treatment process is relatively long, requires more sewage treatment equipment, occupies a large area, has a long on-site construction period, complex operation and maintenance of equipment, and high energy consumption per ton of ...

Problems solved by technology

However, there are some problems and defects in the existing sewage treatment equipment in varying degrees.

[0003] The current traditional sewage treatment process is relatively long, requires more sewage treatment equipment, occupies a large area, has a long on-site construction period, complex operation and maintenance of equipment, and high energy consumption per ton of water

[0004] Moreover, in the current sewage treatment equipment, the treated sludge is not easy to clean from the equipment, and a separate sludge treatment device needs to be installed. These sludge treatment devices are very large and complicated, and the treatment cost per ton of sludge is very high. Different types of sewage require different treatment equipment, requiring very professional personnel for design, installation and maintenance

And when the equipment fails, it cannot be known at the first time, and professionals are needed to judge the point of failure

Since the existing sewage treatment equipment only treats sewage, and a series combination of various sewage treatment equipment is required to treat the sewage to the standard of direct discharge, and the sludge generated in the treatment process needs to be collected and treated separately, so the treatment process is complicated and costly. higher

[0005] In addition, part of the current screen-type drum grill has the function of sieving solid particles and fibers from sewage, and pressing and filtering grid residue, but it needs to be installed in a predetermined civil construction pool, and only the particle size is screened out. The screen slag larger than 1mm cannot remove suspended solids with smaller particle sizes; when the drum grid is intercepted by the screen slag, the entire grid needs to be rotated, and the slag cannot be continuously operated, and the land occupation per ton of water and energy consumption are relatively high.
