化粪池的待解问题
Problems to be solved in septic tank
化粪池作为有一百多年历史的传统环保设施，发挥了重要作用，但是随着社会的进步和城市现代化的发展，也出现了与社会发展背离的问题，亟待解决，主要表现在：
As a traditional environmental protection facility with more than 100 years of history, septic tank has played an important role. However, with the progress of society and the development of urban modernization, the problem of deviating from the social development has also appeared, which is urgently needed to be solved, mainly in the following aspects:
污泥的处置问题
Disposal of sludge
按照化粪池的技术标准，化粪池的污泥清掏时间一般为90天、180天、360天，被清掏的污泥可以作为有机肥料，或者进行无害化处置。但是，随着化肥的广泛使用，社会的发展，使用粪便肥料越来越少，与此同时，我国污泥处置行业严重滞后，粪便污泥的无害化处理不足，我国13.6亿人每年产生超亿吨的粪便污泥，根据统计局数据，2012年无害化处理的粪便污泥只有801.4万吨。大量粪便污泥的清掏转移，造成了二次污染。因此，如果不能解决化粪池污泥的无害化处置问题，化粪池污泥就会成为水污染的污染源，化粪池问题是关系水污染治理成效的环保问题。
According to the technical standard of the septic tank, the sludge cleaning time of the septic tank is generally 90 days, 180 days and 360 days, and the cleared sludge can be used as organic fertilizer, or to do harmless disposal. However, with the extensive use of chemical fertilizer and the development of the society, the use of fecal fertilizer is less and less. At the same time, the sludge disposal industry in China is seriously lagging behind, and the disposal of fecal sludge is insufficient. 1 billion 360 million people in our country produce more than 100 million tons of fecal sludge every year. According to the statistical bureau data, the waste sludge treated innocuous in 2012 Only 8 million 14 thousand tons. A large amount of excrement sludge was removed, resulting in two pollution. Therefore, if the innocuous disposal of septic sludge can not be solved, the septic tank sludge will become the source of water pollution, and the septic tank problem is an environmental problem related to the effect of water pollution treatment.
化粪池的堵塞问题
The problem of clogging of septic tank
化粪池沉积污泥，底部是沉积污泥，表层是漂浮污泥，中间是悬浮污泥及污水，化粪池由隔墙分隔为两格化粪池或三格化粪池，隔墙上的过水洞口位于化粪池隔墙的中间部位，如果化粪池没有及时清掏，当化粪池沉积污泥超出过水洞口的高度，污泥就会堵塞洞口，造成化粪池堵塞。化粪池的堵塞问题严重影响了用户的正常生活，是亟待解决的化粪池应用问题。
Septic sludge deposited on the bottom, the bottom is deposited sludge, the surface is floating sludge, the middle is the suspended sludge and the sewage, the septic tank is divided into two septic tanks or three septic tanks by the partition wall, the water through the hole on the wall is located in the middle part of the septic tank partition, if the septic tank is not removed when the septic tank is removed, the septic sludge is deposited excess sludge in excess. At the height of the water hole, the sludge will plug up the hole and cause the septic tank to be blocked. The clogging problem of septic tanks has seriously affected the normal life of users. It is an urgent problem to be solved in septic tanks.
