Description

Tank-type septic tank for rural sanitary toilet
Technical Field
The utility model belongs to the technical field of domestic sewage treatment, a septic tank is related to, specifically indicate a tank-type septic tank suitable for rural lavatory transformation of plans.
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.
