Embodiment Construction

[0022] figure 1 It is a block configuration diagram of a drainage device for a garbage disposer according to an embodiment of the present invention.

[0023] Drainage from the garbage disposer 1 installed on the sink of the kitchen and cooking, etc., which contains pulverized raw garbage and common kitchen drainage, flows into the solid-liquid separation device 3 through the pipe 2 connected to the garbage disposer 1 . That is, this waste water treatment device does not have a flow path switching device and a flow regulating tank, so that the structure thereof is simplified.

[0024] In the solid-liquid separation device 3, when the waste water containing the shredder of raw garbage during use of the garbage disposer flows in, the solid and liquid components are separated. In addition, when flowing into the kitchen drainage when the garbage disposer is not used, it directly enters the drainage treatment tank 5 because it is a liquid component.

[0025] In the composting devi...

Abstract

The present invention provided an apparatus for treating wastewater wherein an excess sludge separated by a settling separation tank can be surely recovered by a simple structure, and deterioration of treated water quality can be prevented. The apparatus for treating wastewater is equipped with a solid and liquid separator wherein wastewater containing garbage crushed by a disposer is separated into a solid content and liquid content; an apparatus for making compost for treating the solid content separated by the solid and liquid separator; a wastewater treating tank for treating the liquid content separated by the solid and liquid separator; a settling separation tank for settling and separating a sludge content contained in treated water from a wastewater treating tank; and a transfer means for transferring the sludge settled in the settling separation tank to the apparatus for making compost.

Description

technical field [0001] The invention relates to a drainage treatment device, in particular to a drainage treatment device for treating kitchen garbage drainage. Background technique [0002] In the past, in Japanese No. 10792 / 1996 Patent Application Publication (C02F3 / 30) etc., it is disclosed that the waste water of the kitchen waste disposer is separated into solid components and liquid components with a solid-liquid separation device, and the solid components are put into the composting device, A treatment method in which the liquid component is directly poured into the wastewater treatment tank, and the residual sludge in the treated water from the wastewater treatment tank is sedimented and returned to the solid-liquid separation device (the first embodiment of the above-mentioned publication). In addition, the above publication also discloses a method of transferring the liquid component separated by the solid-liquid separation device to the waste water treatment tank ...
