Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0022] Such as figure 1 , 2 As shown, a rural ecological septic tank + wetland system, the sewage discharged from the rural flush toilet is discharged from the water inlet 1 into the septic tank 2. The septic tank 2 includes a manure inlet pipe, a manure pipe, a dividing tank, Cover plate and biogas discharge port 3, three sealed tanks connected by two fecal pipes are intercepted sedimentation and fermentation tank 21, re-fermentation tank 22, and manure storage tank 23 from left to right. The eggs and feces are calculated in 30 days. The death time of the pathogen must stay for 20 days in the interception sedimentation and fermentation tank 21, and 10 days in the re-fermentation tank 22. The volume ratio of the interception sediment to the fermentation tank 21, the re-fermentation tank 22 and the manure tank 23 should be controlled at 2: 1:3, in acc...

Abstract

The invention discloses an ecological excrement treatment system used in a rural area. The ecological excrement treatment system comprises a septic tank, a purification tank and a water-manual aquaticplant ecological ditch, wherein a water inlet is formed in one end of the septic tank and is used for feeding sewage discharged from a water flashing toilet in a rural area into the septic tank; theother end of the septic tank communicates with the purification tank through a communicating tube; and the tail part of the purification tank communicates with the aquatic plant ecological ditch through a communicating tube. The ecological septic tank+wetland system used in the rural area, which is disclosed by the invention, has the advantages of being low in investment, low in management requirement and good in effluent quality, and is adaptive to the characteristics that the management level in the rural area is low and the water quantity is not greatly changed. The system has high social benefits, has large application ranges and wide application prospects in improving living environments in rural areas, and is easy to popularize.

Description

Technical field [0001] The invention belongs to the technical field of sewage treatment, and specifically relates to a new type of non-market town type small septic tank system suitable for rural areas. Background technique [0002] At this stage, the country is implementing a rural toilet improvement campaign, and tens of thousands of dry toilets will be converted into water toilets in recent years. The traditional way to treat water toilet sewage is mainly to connect to the pipe network and collect it in the sewage treatment plant. However, in rural areas with poor conditions, the large-scale laying of pipe networks and the construction of factories are not reasonable in economic considerations, and it was once popular. Rural biogas digesters have encountered more and more problems in practical applications this year, such as high cost, single gas production raw materials, unstable gas production, unsanitary, lack of controllability and difficult disposal of tailings. Therefor...
