1 Biotechnology to treat high-concentration organic wastewater

(1) The high-concentration organic wastewater hydrolysis-aerobic cycle integrated biological treatment technology developed by Xiamen University can realize the high-efficiency biological treatment of high-concentration organic wastewater
.

The technology adopts an intermittently operated hydrolysis-aerobic cycle integrated device, which can reduce the investment cost and operating cost of industrial organic wastewater treatment, quickly and effectively treat the small flow of high-concentration refractory organic wastewater discharged by enterprises intermittently, and realize the availability of water resources.

(2) Harbin Institute of Technology has successfully developed hydrolytic acidification-aerobic process technology for dye wastewater treatment, combined two-phase anaerobic-cross flow aerobic process technology and equipment for high-concentration refractory organic wastewater treatment, and intermittent activated sludge process Five core technologies including automatic control system, UASBAF treatment of high-concentration industrial wastewater technology, and internal circulation hydrolysis-aerobic treatment technology of beer wastewater
.

Three sets of core technologies are at the international leading level, and one set of technologies has reached the international advanced level

(3) ABFT technology treats high ammonia nitrogen wastewater
.

The aerated biological fluidized bed (ABFT) process technology developed by Lanzhou Jiehui Biological Environmental Engineering Co.

The high ammonia nitrogen wastewater discharged by Lanzhou Petrochemical Company during the production of additives and catalysts, the alkali slag wastewater and high-concentration emulsified wastewater produced during the product refining process, the effluent quality of the original sewage treatment plant has not met the discharge standard for a long time.

.

Lanzhou Petrochemical Company sought multiple solutions to solve the two difficult organic wastewater treatment problems, and finally adopted the ABFT process for transformation, so that the effluent quality of 16,000 tons/d of high-concentration organic wastewater reached the national discharge standard

2 Biological rapid separation technology and biodegradable manure treatment technology

Biological rapid water separation treatment technology is a new technology for organic wastewater treatment that has been produced in the past ten years.
It has the advantages of load impact resistance, long filler life and no blockage, low initial investment, low sludge generation, low operating cost, Advantages such as fast speed and convenient management
.

Biological fast-separation ball technology cleverly combines the fast-separation phenomenon and biodegradation to apply to water treatment.

The biodegradable fecal treatment technology mainly uses the principle of microbial metabolism, and decomposes the excrement into low-molecular substances used by the microorganisms through the degradation of bacteria, which is converted into carbon dioxide , water, etc.
, separated in the form of gas, and has high technological and theoretical advances.
Advantages of water saving, energy saving and land saving
.

China Olympic Forest Park adopts a total of 48 buildings with sewage treatment systems.
According to the characteristics of different locations and different functional requirements in the park, 3 types of sewage treatment technologies have been selected and used in different types of buildings.
These 3 types of sewage treatment technologies are: MBR biofilm treatment technology, biological rapid water separation technology and biodegradable manure treatment technology
.

It is the first large-scale urban park in China to achieve zero discharge of sewage in the whole park, achieving the goal of zero discharge of sewage, recycling of sewage and ensuring no pollution to the environment
