Microorganism-based water pollution control system

Abstract

A water pollution control system based on microorganisms provided by the present invention includes a water storage tank, a filter tank and a treatment tank connected in sequence; the treatment tank is provided with a purifying agent inlet, and the purifying agent inlet is prepared with a purifying agent The device is connected, and the purification agent preparation device includes a first preparation chamber, a second preparation chamber and a mixing chamber, and both the first preparation chamber and the second preparation chamber are connected to the mixing chamber, and the mixing chamber is connected to the mixing chamber. said purification agent inlet port; said second preparation chamber includes a culture chamber, a centrifuge chamber and a blending chamber, and said centrifuge chamber is controlled by said controller so that said controller can control the centrifugation time of said centrifuge chamber, so The bacterial solution cultivated in the above-mentioned cultivation room is centrifuged in the centrifuge room and then enters the blending room; thereby ensuring that the sewage treatment work is more environmentally friendly and energy-saving, thereby making the sewage discharge operation more practical, more convenient to use, and easy to promote and use.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a water pollution control system based on microorganisms. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. The level of economic development in my country varies greatly from place to place, and cities with lagging economic development cannot spend a lot of funds on sewage treatment. In terms of sewage treatment, some places still adopt the first-level or first-level enhanced treatment technology, and the effluent cannot meet the requirements of the national second-level discharge standard for the removal of organic pollutants. [0003] According to the clas...

AI Technical Summary

Problems solved by technology

The pure biological oxidation method contains a certain amount of refractory organic matter in the effluent, and the COD value is too high, which cannot fully meet the discharge standard.

Although the adsorption method can remove COD well, there are problems of regeneration of the adsorbent and secondary pollution.

Although the catalytic oxidation method can degrade organic substances that are difficult to biodegrade, there are problems such as high operating costs in practical industrial applications

In particular, the pollutants in the industrial sewage are various, and it is often impossible to remove all the pollutants in the waste water with one process.

It is very difficult to treat industrial wastewater to discharge standards with physical and chemical processes, and the operating cost is high; industrial wastewater contains more refractory organic matter, and its biochemical properties are poor, and the amount and quality of industrial wastewater vary greatly, so biochemical methods are used directly The effect of treating industrial sewage is not very ideal

If the sewage cannot be completely purified and discharged directly, it will re-enter the earth's water cycle system, destroying the ecological environment, and the sewage will also enter the human body and affect human health

The existing sewage treatment equipment cannot effectively treat sewage, so that the treated sewage still contains solid pollutants, which leads to the inability to purify the solid pollutants in time, making the sewage discharge not up to standard, resulting in low purification effect
