Embodiment 1

[0051] Such as figure 1 As shown, a sewage treatment system includes a regulating tank 1, a membrane bioreactor tank 2 and a high-energy physical oxidation reactor 3.

[0052] There are two adjusting pools 1, the adjusting pool is a concrete structure, and the structure of the adjusting pool is a corridor-type water flow channel. The regulating pool is buried underground, and the overlying soil is greened with vegetation.

[0053] In the adjusting pool, there is an adjusting pool liquid level controller 4 and a lifting water pump 5 working in chain, and the control stroke is 80cm. The lifting pump 5 is a self-priming sewage pump with an effective head of 8m and a maximum flow of 5m 3 / h. The lifting water pump 5 is controlled by the interlocking liquid level controller 4 of the regulating tank to realize automatic opening and closing and intermittent work.

[0054] Membrane bioreactor 2 is a concrete structure with an effective volume of 25m 3 , The bottom of the pool is ...

Embodiment 2

[0065] A sewage treatment system includes a regulating tank, a membrane biological reaction tank, a high-energy physical oxidation reactor and a water storage tank.

[0066] There is one adjusting pool, the adjusting pool is a concrete structure, and the structure of the adjusting pool is a corridor-type water flow channel.

[0067] There is a liquid level controller in the regulating pool and a lifting pump to work in chain, and the control stroke is 10cm.

[0068] The membrane bioreactor is a concrete structure with an effective volume of 30m 3 , There is a mud bucket at the bottom of the pool. A Ф4000mm×3000mm biological cage is installed in the membrane bioreactor, and 10,000 porous hollow biospheres are filled in the biological cage. A high-energy physical oxidation reactor is installed at the outlet of the membrane bioreactor.

[0069] When treating sewage, the sewage is collected into the regulating tank first, and undergoes preliminary decomposition and settlement i...

Embodiment 3

[0078] A sewage treatment system includes a regulating tank, a membrane biological reaction tank, a high-energy physical oxidation reactor and a water storage tank.

[0079] There are two regulating pools, the regulating pool is a concrete structure, and the structure of the regulating pool is a corridor-type water flow channel.

[0080] The regulating tank is equipped with a liquid level controller of the regulating tank and a lifting pump to work in chain, and the control stroke is 50cm.

[0081] The membrane bioreactor is a concrete structure with an effective volume of 40m 3 , There is a mud bucket at the bottom of the pool. A Ф5000mm×4000mm biological cage is installed in the membrane bioreactor, and 15,000 porous hollow biospheres are filled in the biological cage. A high-energy physical oxidation reactor is installed at the outlet of the membrane bioreactor.

[0082] The difference between embodiment 3 and embodiments 1 and 2 lies in that the dissolved oxygen concent...

Abstract

The invention provides a sewage treatment system and a sewage treatment method. The sewage treatment system comprises a membrane biological reaction tank. A biological rotary cage is arranged inside the membrane biological reaction tank, wherein multi-hole hollow biological balls are filled inside the biological rotary cage. Biological cotton balls are arranged inside the multi-hole hollow biological balls. The surfaces of the biological cotton balls are chelated with iron ions and are covered with biological membranes. The sewage treatment method comprises the steps that after primary treatment is carried out on sewage in regulating tanks, the sewage is transported to the membrane biological reaction tank, the biological rotary cage is activated, and the multi-hole hollow biological balls can rotate in the sewage; separation is carried out on activated sludge and macromolecule organic matters in the sewage by the biological membranes; aerobes, facultative biological floras and obligated anaerobic bacteria are added to carry out oxygenolysis on a midbody of a molecular chain; an organic compound broken chain of a long chain is converted to the midbody of the molecular chain by the iron ions; viruses and bacteria are sterilized by a high-energy physical oxidation reactor, after detecting, the standard is reached, and discharging is carried out. According to the sewage treatment system and the sewage treatment method, sewage treatment which is rapid, efficient and low in cost can be achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment system and a sewage treatment method. Background technique [0002] With the great development of industry and agriculture, the problem of water pollution is also becoming more and more serious. In our country, there is a large agricultural population, weak infrastructure, and more and more sewage treatment problems, which have gradually attracted people's attention. [0003] Village and town sewage is mainly composed of domestic sewage and agricultural wastewater. The composition of domestic sewage is relatively fixed, mainly containing organic matter such as carbohydrates, proteins, amino acids, fats, etc., which is more suitable for the growth of bacteria and becomes a place for the survival and reproduction of bacteria and viruses; but domestic sewage generally does not contain toxicity, and has a certain fertilizer effect. to irrigate the fields. [0004...
