Embodiment 1

[0036] Such as figure 1 As shown, the upper end of the fecal sewage inlet 1 is connected to the sewer pipe of the building toilet, and the lower end is installed with a descaling device 51 to communicate with the collection and flocculation device 3. The upper part of the collection and flocculation device 3 is provided with a filter residue inlet 4 and communicates with the slag discharge pipe 5. The lower part is provided with No. 1 valve 19 communicating with the solid-liquid separation device 22, and the flocculant tank 6 is installed on the outside to communicate with the collecting and flocculating device 3. The flocculant tank 6 is connected to the pressure pump 28 through the flocculant tank pressure pipe 25. The first material-free alarm 50 is installed.

Embodiment 2

[0038] On the basis of Example 1, as figure 1 , image 3 , Figure 4 , Figure 5 As shown, the solid-liquid separation device 22 is installed below the collection and flocculation device 3, the solid-liquid separation device 22 is composed of a separator 52 and a sedimentation tank 30, and the separator 52 is composed of a separator inner cavity 20 and a separator outer cavity 49 . A separator mesh 43 is provided on the wall of the separator inner cavity 20 , and a backwasher 21 is installed in the separator 52 . Water regularly cleans the separator mesh 43 . The separator outer cavity 49 is provided with a sewage outlet 23 communicating with the sewage filtering device 24 . No. 2 valve 31 is installed at the bottom of precipitation kettle 30 .

Embodiment 3

[0040] On the basis of embodiment one and example two, as figure 1 , Figure 6 As shown, a sludge sterilizing device 33 is installed below the No. 2 valve 31, a dry powder sprayer 34 is installed on the outside of the sludge sterilizing device 33, and a spare sprayer 53 is installed in the opposite direction on the outside. The spare sprayer 53 has the same structure as the dry powder sprayer 34. The nozzle 45 is inserted into the sludge sterilizing device 33 . The dry powder sprayer 34 is provided with an upper cavity 54, a middle cavity 55, and a lower cavity 56, and materials are added through the feeding port 47, and a second no-material alarm 46 is installed outside. The pressure storage tank 48 is connected to the sprayer pressurizing pipe 26 to provide the spray pressure of the dry powder sprayer 34, and the pressurized backup pipe 27 provides the spray pressure of the spare sprayer 53, and the sprayer pressurized pipe 26 and the pressurized spare pipe 27 are connected...

Abstract

The invention relates to an apparatus for processing fecal sewage into reclaimed water at source, belonging to the technical field of environment protection. A collecting and flocculating device connected with a building sewer, a solid-liquid separating device, a sludge sterilizing device, a sewage filtering device, a reclaimed water recycling device and an organic fertilizer fermenting device are included in the technical scheme. The fecal sewage is directly processed by using the apparatus before entering a pipe network. The apparatus is characterized by carrying out solid-liquid separation on the fecal sewage at source, instantly processing the viscous sludge into a loose organic fertilizer and instantly processing the turbid sewage into the reclaimed water which does not contain pathogenic microorganisms. The conventional behindhand mode for the centralized processing of the sewage at a terminal is changed, the construction cost and the running cost are saved, and the environment protection is favorable. The fecal organic fertilizer is recovered and returned to fields to create economic value, the claimed water is recycled to save water resources, and the sewage treatment can be carried out benignly on a profit making rail. The national processing requirements of decrement, harmlessness and resource on pollutants are met. The invention is suitable for processing the fecal sewage of town buildings at source.

Description

technical field [0001] The utility model relates to equipment for treating the source of feces and sewage as reclaimed water, which belongs to the technical field of environmental protection equipment. technical background [0002] Domestic sewage is one of the sources of environmental pollution, mainly composed of various detergent sewage, garbage sewage and fecal sewage used by people in daily life. Among them, the most harmful to human beings is fecal sewage, which is called black water in environmental protection terms, and other sewage is called gray water. Black water pollution not only affects normal life, but also directly threatens human health. [0003] Medical research shows that human and animal excreta are the hosts of various diseases such as infectious diseases, common diseases, frequently-occurring diseases, and parasitic diseases. After the water source is polluted by black water, parasites or other pathogenic bacteria that enter the human body through dri...
