Background
Septic tanks are ubiquitous in cities and rural areas, and domestic septic tanks are not perfect. According to the common practice of China, the sludge cleaning period is generally designed to be 3-12 months, but the sludge cleaning period of many septic tanks is far longer than that, the sludge cleaning period is 3 years and more than 5 years as few as 3 years, and some septic tanks are not asked any more once being built, so that silting is caused. The septic tank is not timely drawn, and the particles partially precipitated rise together with the bubbles, so that the clarified sewage contains a large amount of suspended matters, and the removal rate of the suspended matter content (SS) is reduced. The long-term accumulation of the sediments inevitably reduces the effective water volume of the septic tank and the retention time of the sewage, and sometimes the sewage is almost not retained in the septic tank due to the silting, so that the sewage is discharged, and obviously, the aim of effectively degrading organic matters cannot be fulfilled. Meanwhile, accidents caused by the septic tank are continuous, such as the gas in the tank is sprayed out to burn the human body and explode when absorbing excrement; suffocation and death when workers leave the tank and remove slag, and the like.
A plurality of biological decomposers are sold in the existing market, COD and SS indexes of septic tank sewage can be quickly reduced, sediment silted at the bottom of the septic tank can be effectively decomposed, odor and explosive gas are inhibited from being generated, the number of times of manual cleaning is reduced, and the number of accidents of cleaning and the pollution to the periphery caused by cleaning are reduced. The existing decomposing agent is directly added into the septic tank, and because the sediment at the lower layer of the septic tank is thick, the decomposing agent is difficult to be uniformly dispersed in the septic tank, so that the decomposing effect is influenced, the treatment period is greatly prolonged, the treatment effect is reduced, the using amount of the decomposing agent is increased to a certain extent, and the treatment cost is increased.
