Method for septic tank desilting

Abstract

The invention discloses a method for septic tank desilting. According to the method for septic tank desilting, a special vehicle used for septic tank desilting or/and a moveable container is/are utilized, the caking dirt in liquid dung in a septic tank is crushed in the vicinity of the toilet septic tank, desilting is conducted on the septic tank, the liquid dung is subjected to purification up-to-standard treatment and on-site discharging, solid faeces dirt separated from the liquid dung is collected or stored and transported, and harmless treatment and resource utilization of the septic tank are implemented.

Description

technical field [0001] The invention relates to a method for desilting a septic tank; specifically, a special vehicle equipped with a septic tank desilting equipment and / or a mobile container equipped with a septic tank desilting equipment are used to transport the septic tank The process of crushing solid waste in the tank, purifying wastewater, separating solid and liquid, removing or collecting solid waste in the septic tank, and continuously dredging the dung water in the septic tank belongs to the field of environmental protection technology; Background technique [0002] At present, residential quarters in cities and towns in China are equipped with public toilets and septic tanks. The surface of the feces in the septic tanks often agglomerates. At present, the feces in the septic tanks of public toilets in large and medium-sized cities mainly rely on traditional fecal suction trucks with only a single transportation function to regularly pump out the feces and transpo...

Problems solved by technology

[0002] At present, residential quarters in cities and towns in China are equipped with public toilets and septic tanks. The surface of the feces in the septic tanks often agglomerates. At present, the feces in the septic tanks of public toilets in large and medium-sized cities mainly rely on traditional fecal suction trucks with only a single transportation function to regularly pump out the feces and transport the feces to the outskirts of the city for sewage treatment. If the solid feces are separated from the feces, the percentage of organic matter in the feces can be effectively reduced, which is conducive to reducing the cost of sewage treatment plants for the purification of feces; many urban and rural toilet septic tanks are The excrement and suction trucks do not treat the excrement water after collection, but transport it to remote pits for landfill or discharge anywhere, which seriously pollutes the environment; the excrement water contains a large number of parasites, germs, and harmful substances, and the odor pollutes the environment, especially , feces produce odor and "running, ground, and leakage" phenomena during transportation, causing serious pollution to the environment; transporting urban manure to sewage treatment plants on the outskirts of the city will increase a lot of transportation costs; especially , collect solid human manure in septic tanks and transform them into high-quality pollution-free organic fertilizer products, develop vegetable or crop planting in ecological agriculture, reduce the market supply of synthetic fertilizers, promote and strengthen ecological vegetable planting or ecological agriculture It is of great significance to improve the economic benefits of toilet septic tank treatment;

[0003] There have been many reports on the car for manure water treatment, and the inventor disclosed in the authorized announcement number CN203438914U "Integrated Manure Water Purification and Treatment Car" that "separate the feces solids and waste water in the manure water and adopt the aerobic MBR process The biochemical treatment method has three functions such as waste water purification standard treatment and excrement storage and transportation; the practice shows that...
