Embodiment 1

[0042] see figure 1 , toilet sewage treatment method of the present invention, its main steps comprise:

[0043] 1) For the sewage discharged from the toilet, the solid-liquid separation is carried out immediately to complete the separation of solid matter such as feces from liquid water; the separated solid matter is sterilized and recycled as organic fertilizer;

[0044] 2) Disinfect the sewage separated by preliminary filtration, and then perform a second filtration to separate the dissolved fine solid particles from the liquid again;

[0045] 3) After further advanced treatment, the sewage that has been filtered for the second time can be discharged or reused up to the standard.

Embodiment 2

[0047] The bathroom sewage treatment method described in this embodiment is different from Embodiment 1 in that: the advanced treatment adopts the ecological treatment of surface greening, makes full use of the greening of the community, and uses the surface to filter shallow ditch, and the filter shallow ditch bottom and ditch wall A water-repelling layer is set, and a packing layer, a filter layer, and a soil layer are arranged in turn in the ditch. The packing layer can be pebbles, crushed stones, and porous plates. Water enters the packing layer, and under the action of water pressure, flows along the gaps in the packing layer, is transported to the sump or pipeline, and enters the next treatment process or is discharged up to the standard or reused. 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 upper layer are large and the pores in the lower layer are small. Deep...

Embodiment 3

[0049] The bathroom 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, and the filtering pipelines are prefabricated pipelines. The filter pipe is filled with filter materials such as sand and gravel in sections, 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.

[0050] 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 different pore sizes in the filter pipe. At the same time, a microbial film will ...

Abstract

The invention relates to a sewage treatment method and a sewage treatment device. The toilet sewage treatment method comprises the following steps: firstly conducting solid liquid separation on the sewage discharged from a toilet, then disinfecting, filtering for the second time, and discharging or reusing the sewage reaching the emission standard after further in-depth treatment. The toilet sewage treatment device comprises a sewage tank which is internally provided with a solid liquid separation chamber and a solid storage chamber, a solid liquid separating and filtering tank is installed in the solid liquid separation chamber, a sewage inlet and a solid matter outlet are arranged on the solid liquid separating and filtering tank, and the solid liquid separation chamber is provided with a sewage outlet connection filter pipe. The toilet sewage treatment device and the toilet sewage treatment method disinfect the sewage from the source, the spreading basis of virus and microbes in the sewage is cut off, and the sewage is purified and treated in depth at the same time, so that zero emission of the sewage and resource regeneration and recycle are implemented in a community, and the problem of new pollution of sludge and sediment in a traditional treatment method is avoided effectively.

Description

technical field [0001] The invention relates to a sewage treatment method and a sewage treatment device, in particular to a toilet sewage treatment method and a sewage treatment device. Background technique [0002] At present, urban domestic sewage discharge has become the main source 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. But the facts show that the problem of river pollution remains, 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] To control and protect rivers from pollution, we must solve the problem of domestic sewage discharge from the source. [0004] At present, whether it is a residential reclaimed water treatment station or an urban sewage treatment plant, the treatment technical solution...
