Description

Slag-water separating mechanism of three-grid septic tank in rural toilet revolution engineering construction
Technical Field
The utility model relates to a sediment water separating mechanism, concretely relates to sediment water separating mechanism of three format septic tanks in rural lavatory revolution engineering construction.
Background
At present, in response to the national call on the toilet revolution in rural areas, the treatment of fecal sewage, the treatment of domestic wastewater (including bath wastewater, laundry wastewater and kitchen wastewater of farmer households) and the comprehensive treatment of villages and appearances, the government in Hubei province sets up the technical guidance of the engineering construction of the toilet revolution in rural areas in Hubei province.
According to the requirements of the technical guideline for engineering construction of toilet revolution in rural areas of Hubei province, the rural toilet septic tanks of peasant households adopt the well-known double-urn septic tank or three-grid septic tank, and mainly adopt the three-grid septic tank (see the attached figure 10). The three-grid septic tank is composed of three connected tanks, the middle is communicated by a manure passing pipe, the principle is that the manure is fermented and decomposed for more than 30 days in the tank by mainly utilizing the principle that anaerobic fermentation, the middle layer manure passing and parasite egg specific gravity are greater than the specific gravity of common mixed liquid and easy to precipitate, and the middle layer manure liquid flows to the third septic tank from the first septic tank in sequence so as to achieve the purpose of precipitating or killing parasite egg and intestinal pathogenic bacteria in the manure. The working process of the three-grid septic tank is as follows: toilet liquid dung or/and domestic sewage firstly enter a first grid septic tank from an upper water inlet pipe of a three-grid septic tank, excrement containing more worm eggs is intercepted, and the excrement has enough time for fermentation and disintegration, so that the worm eggs sink and primary decomposition is carried out; the manure liquid of the second septic tank is in a relatively static state, and the eggs floating in the manure are used for continuously sinking to the bottom of the tank for deep decay; the manure is ensured to be fermented and decomposed in the first and second manure pits, and due to the biological antagonism and the chemical action of the manure in the anaerobic decomposition and inorganic process, the germ and egg death or the manure liquid containing few eggs finally enters the third manure pit, and the third manure pit becomes clear after being decomposed for nearly one month and can be used for fertilization. Generally, the volume ratio of the first septic tank, the second septic tank and the third septic tank is 2: 1: 3, and the volume of the third septic tank can be determined according to the fertilizer storage condition; the first-grid septic tank is communicated with the second-grid septic tank through the excrement pipe, the second-grid septic tank is a sedimentation tank and an anaerobic fermentation tank, when the liquid level of excrement reaches a certain height, the excrement flows into the third grid from an excrement water outlet in the upper part of the partition plate, and clear water is discharged out of the septic tank from the third grid after the third grid is sedimentated again.
Generally, a domestic wastewater discharge pipeline and a toilet wastewater discharge pipeline in rural areas are shared pipelines, and both domestic wastewater and toilet wastewater are discharged into a three-grid septic tank; the excrement and urine discharged by each person per day is about 2 liters, the total volume of flushing water is about 12 liters calculated by 10 liters, and the toilet excrement water collected by a 5-person peasant household toilet three-format septic tank per day is about 60 liters; the domestic wastewater is calculated according to 150 liters per household, the toilet liquid dung and the domestic wastewater generated by each household per day are about 210 liters, the water in the toilet liquid dung and the domestic wastewater accounts for about 95 percent, and the solid matters only account for about 5 percent; the capacity of the conventional three-format septic tank is about 1.5 to 2.0 cubic meters, the three-format septic tank can be filled with toilet liquid manure and domestic wastewater only for about 5 days, and the time for farmers with large population to fill the tank is shorter; the septic time of the toilet liquid manure is about 30 days, if the three-grid septic tank is cleaned every 5 days, the labor intensity is high, and the aim of treating the toilet liquid manure can not be achieved without rotting; if the cleaning is carried out for more than 5 days, the toilet liquid dung and the domestic wastewater can be directly discharged out of the three-grid septic tank through the water outlet pipe, and the purpose of remediation can not be achieved; if the volume of the three-grid septic tank is increased, the occupied area is increased, and meanwhile, the production cost and the toilet changing cost of the three-grid septic tank are correspondingly increased and cannot be compensated. On the other hand, although the existing three-format septic tank is designed according to a three-step mode of primary decomposition, deep decomposition and clarification, clear water after clarification is discharged out of the three-format septic tank, in the actual use process, as the volume of the three-format septic tank is smaller, the slag and water after toilet excrement and domestic wastewater flow in cannot be separated, the toilet excrement and the domestic wastewater are directly discharged out of the three-format septic tank without decomposition in the tank, and the three-format septic tank can not play a role at all.
