Problems solved by technology

Since the 1970s, there has been a rigid carrier represented by a honeycomb carrier, but its main disadvantages are small specific surface area and easy clogging; since the 1980s, there have been soft carriers, semi-soft carriers, composite carriers and suspension ball carriers. : The soft carrier overcomes the shortcoming that the hard carrier is easy to block, but the carrier is easy to harden and has a short life; the semi-soft and combined carrier is an improvement of the soft carrier; the suspension carrier has a large modulus and is not easy to block, but the suspension carrier is easy drain

Embodiment Construction

[0009] specific implementation

[0010] The suspended biological carrier of the present invention will be further described in conjunction with the above-mentioned drawings and examples of implementation.

[0011] The suspension carrier of the present invention is designed to have two chambers in the same carrier, and there are obviously different environments between the two chambers, which can provide the growth of a variety of different microorganisms and increase the activity and biomass of microorganisms in the carrier. the size of. The specific shape of the carrier involved in the present invention is uncertain, as long as it can satisfy the simultaneous existence of two different habitats. Such as figure 1 The one shown is a spherical suspended biological carrier, and the double chambers are inner and outer chambers; figure 2 It is a cuboid suspension carrier, and the double chambers are left and right chambers. The biological carrier is fluidized in the whole reac...

Abstract

The invention discloses a biological suspended carrier, namely a double-chamber suspended biological carrier. Compared with a normal carrier, the double-chamber carrier is additionally provided with a region of a different environment so as to form double chambers. By adjusting a carrier material, a surface functional group, an indoor functional carrier and the like, and by designing a carrier chamber structure, a flow form, flow rate and the like, two superior flora habitats with different purifying functions are formed and bi-functional synchronous treatment which can be manually designed and technologically adjusted and optimized is realized in a biological water treatment process. Besides, the characteristics that the biomass is large and the biologic activity is high and the like after the suspended carrier is subjected to film formation are fully utilized by the double-chamber suspended biological carrier, so that the efficiency and the applicability of a biological treatment process are greatly improved.

Description

[0001] technical field [0002] The invention relates to a manufacturing improvement technology of water treatment equipment, which is applied to the suspended biological carrier in the biofilm treatment process of sewage and waste water. Background technique [0003] Efficient carrier is the core of biofilm process and biological treatment of sewage. The development of biological carrier is very fast, and there are many types of carriers currently used, which play an important role in the biological treatment of sewage. Since the 1970s, there has been a rigid carrier represented by a honeycomb carrier, but its main disadvantages are small specific surface area and easy clogging; since the 1980s, there have been soft carriers, semi-soft carriers, composite carriers and suspension ball carriers. : The soft carrier overcomes the shortcoming that the hard carrier is easy to block, but the carrier is easy to harden and has a short life; the semi-soft and combined carrier is an im...
