CS2 micro-power domestic sewage treatment equipment independently developed by our company adopts A2O + MBBR +SBR combination process, which is integrated and includes five components: anaerobic zone, anoxic zone, MBBR aerobic zone, precipitation zone and equipment room. This technology has advantages of both traditional fluidized bed and biological contact oxidation method. It is a new and efficient sewage treatment method, which relies on the aeration in the aeration tank and the lifting effect of the water flow to make the carrier in a fluid state, and then forms the activated sludge growing in suspension and the biofilm growing in adhesion, giving full play to the advantages of the attached phase and the suspended phase. At the same time, aerobic nitrification and anoxic denitrification processes can remove organic matter and achieve the purpose of nitrogen and phosphorus removal. The density of the suspended carrier added to the reactor is close to that of water, so during aeration, it is completely mixed with water, and the environment for microbial growth is gas, liquid and solid three phases. The collision and shear action of the carrier in the water make the air bubbles smaller and increase the utilization rate of oxygen. In addition, each carrier has different biological types inside and outside, some anaerobic bacteria or aerobic bacteria grow inside, and the outside is aerobic bacteria, so that each carrier is a micro-reactor, so that the nitrification reaction and denitrification reaction exist at the same time, thereby improving the treatment effect. As a micro-reactor, the nitrification reaction and denitrification reaction exist simultaneously, so as to improve the treatment effect.

Main advantages:

1, the use of new process reflux mode, no need to set reflux pump to achieve sludge reflux.

2, the use of non-power device to achieve nitrification reflux, saving energy but also greatly improve ammonia nitrogen removal rate.

3, the use of superficial aeration, under the premise of the same aeration effect, the energy consumption is about 1/5 of the conventional products.

4. The power supply of the equipment adopts 220V civil electricity, without 380V industrial electricity.

5, the control system adopts self-developed single-chip microcomputer, the home TV mobile phone is single-chip microcomputer, stable and reliable.

6, with independent intellectual property rights of the control system, the system to achieve wireless wifi big data monitoring function, real-time monitoring of the working current and working status of each power device, timely reporting of various operating parameters during the operation of the equipment, and reserved a variety of monitoring equipment (such as: PH, DO, COD, NH3-N, TN, TP, etc.) data interface, remote debugging, monitoring, control and manual operation compatible. The equipment can realize automatic operation, with automatic fault alarm and anti-theft alarm of the power unit, the site does not need to be equipped with operators, to achieve the true sense of unattended.

7. The operating cost of the equipment is very low, and the operating cost per ton of water inside the equipment is 0.08-0.15 yuan per month, which is 1/8-1/10 of the operating cost of conventional equipment. And basically do not need personnel on-site care and management, saving labor costs and maintenance errors of non-professional managers.

Application field:

This technology is mainly suitable for rural decentralized, aggregated domestic sewage treatment and urban, factory, school and other domestic sewage treatment, in the 220V mains environment, a single equipment processing capacity of 0.5m³/ D-150m ³/d, in high altitude, low temperature areas can also ensure normal use.
