Problems solved by technology

[0003] However, the existing waste water sludge recovery treatment device has a simple structure. Generally, the waste water is filtered to recycle the sludge. The recovery efficiency of the sludge is slow and the recovery effect is poor. The water content in the recycled sludge is relatively large. During the transfer, sewage is likely to drip out, polluting the environment, and the existing waste water sludge recovery and treatment device has a simple structure. During use, the filter is easy to adhere to sludge, which affects its filtration efficiency. Secondly, the sludge pipeline is easy to block, which affects the stability of its use. sex

Abstract

The invention discloses a wastewater sludge recovery treatment device. The device comprises a base and a sludge recovery bin, wherein the sludge recovery bin is fixed to the base through a supportingcolumn, a sewage inlet pipe is connected with one side wall of the sludge recovery bin, a first driving motor is fixed to the center part of the top of the sludge recovery bin through bolts, a stirring shaft is rotatably connected with the bottom of the first driving motor, a filtering cover is fixed to the interior of the sludge recovery bin, water outlet pipes are connected with the outer surface wall of the bottom of the sludge recovery bin, and a first sludge discharging pipe is connected with the center part of the bottom of the filtering cover. In the wastewater sludge recovery treatmentdevice, the sludge recovery bin, a dehydration box and a second sludge discharging pipe which is provided with electric heating pipes and used for drying are arranged, thus sludge in wastewater can be directly recovered, dehydrated and dried, the integration level is high, functions are complete, use is convenient, the sludge subjected to recovery treatment can be directly transferred, and duringtransferring, no sewage percolates, so that the environment is protected.

Description

technical field [0001] The invention relates to the technical field of waste water sludge treatment, in particular to a recovery treatment device for waste water sludge. Background technique [0002] Wastewater sludge refers to the accumulated solid sediment separated from various types of water, wet or mixed with liquid components, is the product of natural or artificial treatment processes, urban sewage, water supply plants and industrial wastewater treatment stations, in the production process A large amount of sludge is continuously discharged in the sewage plant, and the amount of sludge in the sewage plant accounts for about 0.3%~0.5%± (calculated with a water content of 97%) of the treatment capacity. These sludge need further treatment. [0003] However, the existing waste water sludge recovery treatment device has a simple structure. Generally, the waste water is filtered to recycle the sludge. The recovery efficiency of the sludge is slow and the recovery effect is...
