Embodiment 1

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

[0045] 1) For the sewage discharged from the kitchen, filter it immediately after discharge to realize the separation of solids and liquids; sterilize the separated solids, compress them into blocks, and use them as organic fertilizers;

[0046] 2) For the separated liquid sewage, depending on the difference in specific gravity between oil and water, oil-water separation is realized through liquid level overflow; the separated oil is collected and reused as industrial oil raw materials;

[0047] 3) Disinfect the sewage discharged from the toilet immediately after discharge, and then filter to separate solids and liquids, and compress solids into blocks as organic fertilizers;

[0048] 4) Disinfect the waste water obtained in step 2) after oil and water separation, and then merge with the waste water in step 3) after solid-liquid separation, and carry out furth...

Embodiment 2

[0051] The difference between the kitchen and toilet drainage treatment method of this embodiment and that of Embodiment 1 is that the advanced treatment includes the step of filtering sewage by using a filter pipe, using the sand and stone filter pipe buried in the community, The filter material is filled in sections in the pipeline, and along the direction of the filter pipeline, the pores of the filter material filled in sections are distributed in such a way 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.

Embodiment 3

[0053] The difference between the kitchen and toilet drainage treatment method of this embodiment and embodiment 1 or embodiment 2 is that the advanced treatment includes the step of adopting the ecological treatment of surface greening, making full use of the greening of the community, and adopting the surface to filter shallow ditches. Filter the shallow ditch bottom and ditch wall to set up a water-repellent layer, and set a filler layer, a filter layer, and a covering soil layer in turn in the ditch. Plant water hyacinth, large algae, water hyacinth and other plants in the covering soil layer to reduce the nitrogen and phosphorus in the water. and other substances are removed, and at the same time, permeation filtration is performed.

Abstract

The invention relates to a method and a device for treating water drained from kitchens and bathrooms. A method for treating water drained from kitchens and bathrooms comprises the following steps: 1) immediately filtering sewage drained from kitchens so as to realize solid-liquid separation; 2) carrying out oil-water separation on liquid sewage; 3) immediately disinfecting sewage drained from bathrooms, and then filtering the sewage so as to realize solid-liquid separation; 4) disinfecting the wastewater subjected to oil-water separation, mixing the obtained water with the sewage subjected to solid-liquid separation in the 3), and further filtering the obtained mixture; 5) after the obtained water is subjected to further depth processing and reaches the standards, discharging or reusing the obtained product. A device for treating water drained from kitchens and bathrooms is provided with a solid-liquid separation chamber and a water storage chamber arranged in a sewage tank, the solid-liquid separation chamber is divided into a solid-liquid separation chamber for water drained from kitchens and a solid-liquid separation chamber for water drained from bathrooms, an oil storage tank communicated with the solid-liquid separation chamber for water drained from kitchens is arranged in the sewage tank, and sewage in the water storage chamber enters a filter pipe. According to the invention, the discharge of sanitary sewage and the cyclic utilization of wastes in communities are realized.

Description

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