Problems solved by technology

However, it does not involve the conditions and parameters of important processes such as anaerobic, facultative, and aerobic biological treatment processes. In practical applications, it is highly dependent on temperature and has poor impact load resistance. These aspects are extremely important in practice.

Embodiment Construction

[0035] As shown in the figure, in the process flow of Fig. 1 of the present invention (flushing toilet), it includes:

[0036] 1. Pretreatment (solid-liquid separation or liquid-liquid separation to obtain the supernatant to be treated and the solid to be collected);

[0037] 2. Anaerobic reactor strengthens anaerobic treatment;

[0038] 3. Aerobic biological treatment in aerobic reactor;

[0039] 4, facultative oxygen reactor facultative oxygen biological treatment;

[0040] 5. Water disinfection and sterilization treatment after biological treatment; or membrane treatment;

[0041] 6. Water balance treatment (when the water is recycled, it can meet the requirements of zero discharge of water on the premise of ensuring the balance of the total amount of circulating water in the system);

[0042] 7. The treated domestic miscellaneous water (reclaimed water) is put into the container for use.

[0043] Take the fecal sewage recycling method as an example: First, the circulat...

Abstract

The invention discloses a biological disposing method of effluent through circulating ecological system, which comprises the following steps: 1) predisposing waste water; separating solid from liquid or liquid from liquid; obtaining supernatant; 2) entering the supernatant into serial anaerobic and aerobic disposing disposal; cutting and guiding disposed flow through guide flow or conductive pipe; setting three-phased separating device to reinforce anaerobic disposal; 3) sterilizing the water; 4) pumping or reflowing water from sterilizing device to container; controlling dissolved oxygen density or air aerating time; setting the air cutting and aerating time at 1:0.4-5.

Description

technical field [0001] The invention belongs to a sewage treatment method and device, in particular to a biological treatment method and device for water recycling and reuse of an ecological sanitation system, especially a circulating water sanitation system that treats sewage such as feces and can achieve zero discharge of water. Background technique [0002] China is one of the water-scarce countries in the world, and its per capita water resources are only 1 / 4 of the world's per capita water resources. The shortage and pollution of water resources have seriously affected my country's national economic construction and people's normal life. If the domestic water can be recycled, that is, the standard of domestic miscellaneous water (reclaimed water), and a domestic circulating water sanitation system can be formed, the amount of water can be greatly saved. For example, toilet flushing water is not only an important part of domestic water, but its sewage is also one of the ...
