A kitchen drainage treatment method and device

Abstract

The invention discloses a kitchen effluent treatment method which comprises the following steps: 1, firstly, immediately filtering kitchen effluent to separate solid waste from a liquid; 2, for the separated liquid, realizing separation of oil and water according to the difference of specific weights of oil and water; 3, disinfecting the waste water after the oil and water are separated, and then performing secondary filtration; 4, further deeply treating the sewage subjected to the secondary filtration and then discharging or recycling when the filtered sewage reaches the standard. The kitchen effluent treatment device has a structure that a solid and liquid separation chamber and an oil storage chamber are arranged in a sewage tank, a solid and liquid separation filtering box is arranged in the solid and liquid separation chamber and connected with a sewage pipe, a water outlet is formed in the lower part of the solid and liquid separation chamber and is communicated with a water storage chamber arranged at the lower part of the oil storage chamber, an oil overflow hole is formed in the upper part of the solid and liquid separation chamber, a filtrate layer is arranged between the oil storage chamber and the water storage chamber, and sewage of the water storage chamber enters a filtering pipe. According to the kitchen effluent treatment method and the kitchen effluent treatment device, kitchen effluent is dispersed and ecologically treated from the source, and thus the problem of new pollution caused by sludge and sediments in a conventional treatment method is avoided.

Description

technical field

[0001] The invention relates to a kitchen drainage treatment method and a kitchen drainage treatment device. Background technique

[0002] At present, urban domestic sewage discharge has become the main source of river pollution. Since 2001, the construction of residential reclaimed water stations and urban sewage treatment plants has been carried out in various parts of our country. 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. Therefore, to control and protect rivers from pollution, we must solve the problem of domestic sewage discharge from the source.

[0003] At present, whether it is a residential reclaimed water treatment station or an urban sewage treatment plant, the treatment technical solution is to first collect the sewage from multiple househ...

Examples

Embodiment 1

[0037] see figure 1 , kitchen drainage treatment method of the present invention, comprises the following steps:

[0038] 1) Collect the sewage discharged from the kitchen, filter it immediately, and separate the solid waste from the liquid; for the separated solid waste, after disinfection treatment, it can be recycled as organic fertilizer;

[0039] 2) For the separated liquid, the separation of oil and water is realized according to the difference in specific gravity between oil and water; the separated oil is collected and reused as industrial oil raw material;

[0040] 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;

[0041] 4) After further advanced treatment, the sewage after the second filtration treatment is discharged or reused up to the standard.

Embodiment 2

[0043]The bathroom sewage treatment method of this embodiment differs from that of Embodiment 1 in that: for the sewage that has been filtered for the second time, the method of surface greening ecological treatment is used for further advanced treatment: the greening of the community is fully utilized, and the surface is filtered Shallow ditch, the bottom and wall of the filtering shallow ditch are provided with a water-resisting layer, and a filling layer, a filter layer and a covering soil layer are arranged in the ditch sequentially from bottom to top.

[0044] The packing layer can be made of pebbles, crushed stones, or perforated plates. Its main function is to support the filter layer above. Gap flow, transported to the sump or pipeline, enter the next treatment process or discharged or reused up to the standard. The filter layer can be composed of filter materials with different pores. The pores of the filter layer are distributed in such a way that the pores in the up...

Embodiment 3

[0046] The bathroom sewage treatment method of this embodiment, the toilet sewage treatment method described in this embodiment, is different from Embodiment 1 or Embodiment 2 in that: the advanced treatment includes the step of filtering sewage by using sand and gravel pipelines, so The above-mentioned filter pipeline adopts prefabricated pipeline, and filter materials such as sand and gravel are filled in sections in the filter pipeline, and nitrogen-loving and phosphorus-loving microorganisms are put into the filter material to form a filter membrane together with the filter material to complete the advanced treatment of water. . Along the direction of the filter pipe, the pore distribution of the filter material filled in sections sequentially is that the water inlet end is large and the water outlet end is small.

[0047] The sewage that has been filtered for the second time enters the sand filter pipe buried in the community, and the water is filtered through pores of di...
