Description
Technical Field
The invention belongs to the technical field of domestic sewage treatment, and relates to a septic tank, in particular to a tank type septic tank suitable for rural toilet improvement.
Background
With the rapid growth of economic construction, the living conditions of rural areas are gradually improved, and the traditional rural toilets are mostly open-air squatting pan type dry toilets which are dirty, smelly, rich in mosquitoes and easy to spread diseases; the water cannot be flushed, and particularly, when raining, the water is easy to flush and enter river channels to pollute underground water, so that the environmental sanitation is seriously influenced, and great unsafe factors exist. According to statistics, 80% of infectious diseases in rural areas of China are caused by toilet excrement pollution and unsanitary drinking water, wherein the infectious diseases related to the excrement are more than 30. The rural village toilet improvement plan is widely implemented, so that the morbidity of rural intestinal infectious diseases and parasitic diseases can be effectively reduced, and the health level and the life quality of rural residents are improved. However, the core of the rural toilet is 'improved' in which the soil pit of the original dry toilet is replaced by an impervious septic tank, so that the problems of feces leakage, seepage and leakage are avoided, and the problems of dirtiness, odor, more mosquitoes, easy disease transmission and serious environmental pollution of the traditional dry toilet are solved. Therefore, what kind of septic tanks are suitable for the needs of changing toilets in rural villages in various places, in particular to collapsible loess geology in northern frigid and arid areas of China.
At present, the septic tank for rural toilets has the problem of unreasonable structural design. Firstly, the tank body is manufactured by adopting an injection molding two-half splicing process currently, the tank body is divided into an upper part and a lower part, a layer of adhesive tape or glue is coated at a connecting seam and then is connected and fixed by screws and nuts, and the tank body is easy to leak due to the conditions of improper installation, sunken terrain, rusty screws and the like. Secondly, the connecting ports of the tank body and the pipeline of the septic tank are laterally and transversely arranged, and the connecting part of the tank body and the pipeline has serious hidden danger of leakage, dirt, odor and environmental pollution and has the risk of polluting underground water; and the joint of the pipeline and the tank body bears larger vertical soil pressure, so that the service life of the pipeline can be greatly influenced. And thirdly, the lateral connection of the pipelines can form a lower bent angle, so that feces are easy to deposit, the pipelines are blocked, the freezing is easy to happen in winter, the normal cleaning is influenced, the construction amount is increased, and the like. In addition, the existing septic tank has insufficient strength and poor bearing and compression resistance performance, and is easy to have the problems of sinking, deformation, cracking and the like when being buried below a frozen soil layer. In addition, the pool body has large appearance and occupied area, so that the excavation and landfill earthwork amount is large, and the internal volume utilization rate is not high. Finally, the northern area of China has long winter time, cold climate and low environmental temperature. When the indoor temperature of the toilet is below zero, the excrement and the liquid dung retained in the pipeline are easy to freeze; even the septic tank and the excrement inlet pipe can be frozen, so that the normal use of the toilet is influenced, and the layering and fermentation effects of the excrement are influenced. Therefore, there is a need for innovations in the structure of the existing septic tank to solve the above technical problems.

And the excrement in the tank is easy to deposit in the groove, thereby improving the microbial fermentation effect and ensuring that the sewage treatment capacity of the invention is obviously higher than that of the traditional septic tank with the same volume. In addition, a plurality of reinforcing ribs 14 are arranged at two ends of the tank body 1, and bases 9 are arranged at two sides of the bottom of the tank body 1, so that the integral bearing strength and the installation stability of the tank body are further ensured. The tank body 1 is manufactured by adopting a rotational molding integral forming process, and the raw material adopts polyethylene high polymer material resin. The product is formed without pressure, has good edge strength and high compressive strength, is acid-base resistant and corrosion resistant, and is not easy to dent, deform and crack; the problems that the existing septic tank is manufactured by adopting an injection molding two-half splicing process, is easy to crack and leak, and cannot be suitable for collapsible loess areas which are easy to collapse can be solved.
Furthermore, the top of the tank body 1 is provided with a cleaning opening 13 for cleaning feces or checking the condition in the tank, the cleaning opening 13 is connected with a heat preservation pipe 6, the heat preservation pipe 6 is downwards communicated with the tank body 1 vertically, and the side position of the top seal of the heat preservation pipe 6 is connected with an exhaust pipe 7. By arranging the heat preservation pipe 6, the vertical length of the heat preservation pipe 6 is more than or equal to the thickness of a frozen soil layer embedded in the septic tank, so that the tank body 1 is positioned below the frozen soil layer, the problem that liquid dung in the septic tank and a pipeline is frozen can be solved, and the process and the cost of adding a heat preservation layer on the ground are saved; when the heat preservation pipe 6 is buried underground, the positioning effect can be achieved, and the lateral displacement of the septic tank along with the terrain can be effectively reduced; and the internal air pressure of the septic tank can be adjusted and the purpose of capacity increasing is achieved. Odor in the septic tank upwards gathers in insulating tube 6, is discharged by blast pipe 7, and the outside diameter of blast pipe 7 adopts 110mm tubular product, and the height should surpass lavatory roofing more than 50cm at least, and will avoid the right angle and turn.
The effective volume of the pot-type septic tank can be calculated according to the sum of the total number of family population, excrement discharge amount and water consumption for flushing the toilet bowl according to the sum of 2L/(person and day) and the total volume 1/3 of water added before use, and the excrement is required to be stored in the previous stage septic tank for more than 30 days. Specifications are mainly divided into 0.2 m, 0.5m, 0.75m, 1.0m, 1.5m, 2.0m, 3.0m, 5.0m, 10m, 500 m, and the like for thin film cultivation. The problems of small capacity and single selectivity of other septic tank products are solved.
The above embodiments are merely exemplary and are not intended to limit the present invention, and it should be noted that other equivalent variations and modifications made by those skilled in the art in light of the teachings of the present invention should be considered to be within the scope of the present invention.
