specific Embodiment approach 2

[0028] Specific implementation mode two: combination figure 2 , the difference between this embodiment and specific embodiment one is: the facultative pond reactor 11 is cylindrical, the aerobic pond reactor 17 is cylindrical, the facultative pond reactor 11 and the aerobic pond The effective volumes of the reactors 17 are equal, and the integrated reactor with the same center of circle at the bottom composed of the facultative pond reactor 11 and the aerobic pond reactor 17 is a stable pond reactor. Others are the same as the first embodiment.

[0029] The facultative pond reactor 11 described in this embodiment has an effective volume of 150 L, a radius of 17.5 cm, and a height of 156 cm.

[0030] The effective volume of the aerobic pond reactor 17 described in this embodiment is 150L, ​​the radius is 35cm, and the height is 39cm.

specific Embodiment approach 3

[0031] Specific implementation mode three: combination image 3 , the present embodiment is a method for treating low-temperature domestic sewage in an attapulgite-stabilized pond compound reactor, which is specifically completed according to the following steps:

[0032] 1. Add anaerobic strain sludge to the facultative pond reactor 11, and add aerobic strain sludge to the aerobic pond reactor 17;

[0033] 2. Fill the storage tank 2 with low-temperature domestic sewage at a temperature of 6-10°C, and transfer the low-temperature domestic sewage into the high-level water tank 1 through the diversion pipe I3 ​​through the submersible pump 4, and the sewage flows from the high-level water tank 1 through the drop water Device 7, the low-temperature domestic sewage is dropped from the water-dropping device 7 into the water collection tank 6 in the form of a shower-type water drop to form water-drop aeration, so as to increase dissolved oxygen in the low-temperature domestic sewage...

Abstract

The invention provides an attapulgite-stabilization pond combined reactor and a low-temperature domestic sewage advanced treatment method thereof, relating to the field of sewage treatment, particularly a low-temperature domestic sewage advanced treatment reactor and method. The invention aims to solve the problems of high investment, high energy consumption and low efficiency in the existing rural domestic sewage treatment method in severe cold regions. The attapulgite-stabilization pond combined reactor is composed of a drop system, a facultative pond water inlet system, a facultative pond water treatment system, a facultative pond water outlet system, an aerobic pond water treatment system and an aerobic pond water outlet system. The method comprises the following steps: 1. inoculating, and culturing; 2. enriching dissolved oxygen; 3. starting the facultative pond reactor; 4. starting the aerobic pond reactor; and 5. automatically operating the stabilization pond reactor, thereby completing the low-temperature domestic sewage treatment. The reactor and method are mainly used for treating low-temperature domestic sewage.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a reactor and a method for advanced treatment of low-temperature domestic sewage. Background technique [0002] Rural domestic sewage treatment in severe cold areas is faced with typical problems of high investment, high energy consumption, low efficiency, and substandard drainage, which seriously damages the water environment quality in the area, endangers the water safety of villagers, and restricts the construction of national green villages and towns. Therefore, research on rural domestic sewage treatment in severe cold areas is very necessary. In severe cold areas, the rural economic foundation is relatively weak, the sewage treatment facilities are not perfect, the population is small, the distribution is wide, and the domestic sewage water volume is small and the concentration is low. Select a decentralized sewage treatment model suitable for rural areas in severe cold are...
