Technical Field

The invention relates to the technical field of garbage treatment, in particular to a solid-liquid separator, a using method and garbage treatment equipment.

Background

In the current domestic garbage treatment station, filter pressing liquid pressed out by a garbage compressor is generally directly discharged into a sewage tank and then is sucked and transported by a sewage suction truck for treatment or is pumped to a sewage treatment workshop in the station. Because the filter pressing liquid contains more solid-phase impurities, the filter pressing liquid is easy to cause sedimentation in a sewage tank after entering the sewage tank, and needs to be manually cleaned and transported at regular intervals.

At present, the effluent water sump in the domestic waste transfer station is generally designed into a sedimentation tank and a leachate tank, the sediment of the sedimentation tank and the scum of two tanks need to be regularly and manually dug (suitable sludge pump is not used for clearing up the sediment of the effluent water sump of the domestic waste transfer station at present), the dug-out residue needs to be manually transferred to a two-layer unloading platform, and then the working environment is severe and the environment in the station is influenced.

At present, the treatment of the press filtrate mainly has the following problems:

1. the filter pressing liquid is discharged to a sewage tank through a concealed pipe, and the filter pressing liquid has the disadvantages of high slag content, poor flowability and high risk of blockage of the concealed pipe, and needs to be additionally provided with a flushing port, so that the water consumption is increased.

2. The filter pressing liquid entering the sedimentation tank settles the residue with large specific gravity, and the residue with small specific gravity floats upwards, and needs to be cleaned manually and periodically.

3. When the sewage pool is cleaned, the odor overflows to cause air pollution in the station.

4. The residue that clears up out needs artifical secondary to transport to the platform of unloading, causes the inside and outside air pollution of station.
