Embodiment 1

[0044] see figure 1 , the centralized treatment method of kitchen garbage and drainage of the present invention, comprises the following steps:

[0045] 1) Collect the sewage discharged from the kitchen and the crushed kitchen waste, filter it immediately, and separate the solid waste from the liquid;

[0046] 2) For the separated liquid, the separation of oil and water is realized according to the difference in specific gravity of oil and water;

[0047] 3) For the waste water after oil-water separation, first carry out disinfection treatment, and then perform a second filtration to separate the soluble fine solid particles in the sewage from the liquid again;

[0048] 4) After further advanced treatment, the sewage after the second filtration treatment is discharged or reused up to the standard.

Embodiment 2

[0050] The centralized treatment method for kitchen waste and drainage in this embodiment differs from that in Embodiment 1 in that: the sewage is further treated in depth by adopting the ecological treatment method of surface greening: making full use of the greening of the community, and adopting shallow ditches for filtering on the surface. The bottom of the ditch and the wall of the ditch are provided with a water-resisting layer, and the filling layer, the filter layer, and the covering soil layer are successively arranged in the ditch from bottom to top. Substances such as phosphorus are removed, and osmotic filtration is performed at the same time.

Embodiment 3

[0052] The centralized treatment method for kitchen garbage and drainage in this embodiment is different from that in Embodiment 1 or Embodiment 2 in that: the advanced treatment includes the step of filtering sewage by using a filter pipe, and the filter pipe is divided into sections Fill the filter material, follow the direction of the filter pipe, and the pore distribution of the filter material filled in sections is that the water inlet end is large and the water outlet end is small, and nitrogen-loving and phosphorus-loving microorganisms are put in at the same time.

Abstract

The invention relates to a treatment device for kitchen wastes and wastewater. A centralized treatment method for kitchen wastes and wastewater comprises the following steps: (1) collecting the kitchen wastewater and the smashed kitchen wastes, and instantly filtering to separate solid wastes from liquid; (2) performing oil-water separation on the separated liquid; (3) disinfecting the separated wastewater at first and then filtering the separated wastewater for the second time; (4) further deeply treating the wastewater subjected to secondary filtering, and discharging with standards or reusing. According to the centralized treatment device, a solid-liquid separation chamber and an oil storage chamber are formed in a wastewater box; kitchen waste inlets are correspondingly formed in a top plate of the solid-liquid separation chamber and a solid-liquid separation filter box in the solid-liquid separation chamber, and the solid-liquid separation filter box is provided with a wastewater inlet; a water outlet in the lower part of the solid-liquid separation chamber is communicated with a water storage chamber in the lower part of the oil storage chamber, and an oil overflowing hole formed in the upper part of the solid-liquid separation chamber is communicated with the oil storage chamber, and wastewater in the water storage chamber enters a filter pipe.

Description

technical field [0001] The invention relates to a kitchen garbage and drainage treatment device, in particular to a kitchen garbage and sewage centralized treatment method and an integrated treatment device. Background technique [0002] At present, municipal solid waste and sewage discharge have become the main sources of river pollution. Since 2001 in our country, the construction of residential reclaimed water stations and urban sewage treatment plants has been carried out in various places. However, the facts show that the pollution of the river is still there, the construction of sewage treatment facilities is slow, and the effect of pollution control is not obvious enough. Moreover, it also brings about the problem of sludge disposal. [0003] The existing urban domestic garbage and sewage treatment methods, whether it is the reclaimed water treatment station in the community or the urban sewage treatment plant, the treatment plan is to first collect the sewage from ...
