Description

An underground integrated rural domestic sewage treatment system

technical field

The utility model belongs to the technical field of sewage treatment, more specifically, the utility model relates to a ground type integrated domestic sewage treatment system.

Background technique

Domestic sewage treatment refers to the use of professional technical means and sewage treatment equipment to treat sewage generated in life, degrade and kill harmful substances and germs in domestic sewage, so that the treated sewage can be discharged up to standard, which can prevent harmful substances and Germs enter the atmosphere and the external water cycle to protect the environment, and the sewage can be recycled and reused, saving water resources.

At present, the collection and treatment of sewage in most parts of our country adopts the centralized collection and treatment method, but in rural areas far away from towns and factories, the recycling and treatment of sewage has not been popularized. Some farmers in rural areas directly discharge domestic sewage, human and animal feces and sewage into the environment, which not only causes environmental pollution but also wastes resources. Low, sewage treatment is not thorough.

The existing rural domestic sewage treatment facilities directly discharge the feces in the septic tanks directly into the sewage treatment facilities without setting up sewage adjustment and buffer facilities. Since the characteristics of rural sewage are discontinuity, sometimes it is more and sometimes less, so the sewage The treatment method makes sewage treatment inefficient, resulting in unreasonable allocation of manpower, time and other costs. Most rural domestic sewage still fails to meet the national "Urban Sewage Treatment Plant Pollutant Discharge Standard" (GB18918-2002) Level I ( B) standard, it cannot be directly discharged into rivers and lakes, nor can it be recycled.

Working principle: As shown in Figure 3, according to the design scheme of an underground integrated rural domestic sewage treatment system of the present invention, the sewage generated in the farmer's courtyard is connected to the domestic sewage septic tank through the pipeline, and the solid state in the kitchen sewage The organic matter is decomposed by anaerobic fermentation in the kitchen sewage septic tank to kill the eggs of mosquitoes and flies. The floating matter is human and livestock manure, which is the main source of farmyard manure. The washing sewage flows directly into the regulating tank 1 through the pipeline, and does not connect to the domestic sewage septic tank. When the sewage in the kitchen sewage septic tank and domestic sewage septic tank reaches the preset position, it flows to the regulating tank 1 through the pipeline, and the suspended solids and other water-soluble pollutants enter the regulating tank 1, and the regulating tank 1 is used to solve the secondary pollution. The first is to buffer the amount of sewage entering the final treatment device. The characteristic of rural sewage is discontinuity, so as to improve the efficiency of small sewage treatment pool 2 in sewage treatment. The second is to further anaerobically ferment organic matter and block solid matter that cannot be hydrolyzed. A buoyancy switch is preset in the adjustment pool. When the sewage in the pool reaches a certain amount, the pump will pump the sewage into the small sewage treatment tank for ultimate treatment of the sewage. A sludge suction pump is pre-installed in the sewage treatment barrel, which can discharge excess sludge from time to time. Because the kitchen sewage contains too much oil in the farmhouse, the oil needs to be separated by the grease trap 15 before entering the septic tank, and the rest is the same as the sewage treatment in the farmhouse yard.

After the above technical scheme classifies and treats rural domestic sewage, it is finally uniformly passed into small sewage treatment tanks. The treatment method is efficient and environmentally friendly. The treated sewage not only meets the direct discharge standard, but also recycles fecal sewage and sewage in small sewage treatment tanks. Utilization can recycle a large amount of farmyard manure, organic fertilizer and agricultural water.

In the above technical solution, the structure of the regulating pool 1 also includes:

The sewage inlet 14 connected with the septic tank is arranged at the upper end of the regulating tank 1;

A plurality of V-shaped packing chambers 6 are arranged at the bottom of the regulating tank 1 .

In the above technical solution, the structure of the small sewage treatment tank 2 also includes;

The medicine filling port 10 is arranged on the upper end of the small sewage treatment bucket 2, and is used to inject medicine into the small sewage treatment bucket to kill germs;

Two agitating shafts 7 installed in parallel are fixed on the wall of the small sewage treatment barrel 2, and each agitating shaft 7 is provided with three rows of agitating paddles 8, which agitate the sewage, speeding up the speed of drug sterilization, sterilization and disinfection also more thorough;

The sludge suction pump 5 is arranged at the sludge outlet 11 at the bottom of the small sewage treatment tank 2 .

In the above technical solution, the structure of the grease trap includes:

The swill inlet 16 is arranged on the top of the grease trap 15, and a filter box 17 is installed below it;

There are two sets of partitions inside the grease trap, each group of partitions includes an upper partition 18 and a lower partition 31, the upper partition 18 is installed on the upper wall of the grease trap 15, and the lower partition 31 is installed on the bottom of the grease trap 15 Two groups of partitions divide the grease trap into three chambers, which are respectively the first chamber 19, the second chamber 20 and the third chamber 27, wherein the second chamber 20 top is provided with an oil scraper, and the second chamber The three-chamber is provided with a three-way pipe 22 to communicate with the septic tank. The three-way pipe includes an upper vertical outlet 21, a lower vertical inlet 24 and a horizontal water outlet. The kitchen sewage enters the grease trap through the swill inlet, and is first filtered by the filter box. The solid oil in the swill is filtered, and the remaining liquid swill enters the first chamber of the grease trap. There is a vertical passage between the upper partition 18 and the lower partition 31. Since the density of the sewage is greater than the oil, the oil will float on the In the upper layer of sewage, when the oil and sewage liquid level in the first chamber is higher than the lower end of the upper partition, most of the sewage flowing into the second chamber 20 from the vertical channel is sewage, and the oil will be blocked in the first chamber , by the same way, the amount of oily contamination in the sewage entering the third chamber 27 will be very small.

In the above technical solution, the surface of the V-shaped packing chamber 6 is provided with a drawing wire 601 for attaching fermentation colonies, and the drawing wire 601 is fixed on the surface of the packing chamber 6 through a plastic ball, and the drawing wire can attach more fermentation bacteria to expand the fermentation contact area. Increase the fermentation speed of sewage.

Vertical scraper 25, which is connected with horizontal bar 30, wherein horizontal bar 30 is installed in the track 23 of the outer wall of the grease trap, scraper 25 is installed in the grease trap, and one end of horizontal bar 30 is connected with inclined pull bar 29;

The oil collecting basket 26 is located outside the oil trap. The oil inlet of the oil collecting basket 26 is installed in the second chamber 20 of the oil trap. The height of the lower end of 25 is the same. By pulling the pull rod, the scraper moves to the side of the oil collecting basket on the track, and the oily foam on the upper layer of the second chamber can be scraped into the oil inlet of the oil collecting basket 26. The oily foam passes through the oil inlet and then Enter the oil collecting basket, wherein, pulling the pull rod can be completed by manpower.

In the above technical solution, the inner wall of the small sewage treatment tank 2 is provided with a wear-resistant layer 9, and the small sewage treatment tank is also provided with a standard discharge port 28, and it is provided with a valve, and the sterilized sewage is discharged into the river through the standard discharge port Lakes can also be recycled as water for agriculture.
