Description

Energy-saving sewage treatment system

Technical Field

The utility model relates to a sewage treatment system, in particular to energy-saving sewage treatment system belongs to sewage treatment device technical field.

Background

At present, with the emphasis of the country on environmental protection, strict control of pollutants discharged into natural ecological environment is required all over the country, and the pollution level is raised to a very high level. At present, the work of environmental protection is extended to the sewage treatment of rivers, villages and towns and the like in various cities. However, the amount of sewage discharged from rivers, villages and towns is usually changed in a seasonal periodic manner, and the change range is large. Usually, the maximum amount of water is about 5 times the minimum amount of water. When a sewage treatment system is newly built, the design and the determination of the water quantity are often defined according to the peak value, namely the highest water quantity. Therefore, for the design of sewage treatment of rivers and villages and small towns, the treatment system is designed according to the highest water yield. However, the highest water amount is usually concentrated in summer and autumn (factors such as large water consumption and rainy season), the water treatment system is in full load in two or three months in one year, and most of the other seasons are in low water amount. Therefore, the sewage treatment system is in a low-load state for a long time, the stability of the system is not facilitated, the sludge amount of the system is reduced for a long time, the actual treatment capacity of the whole equipment is reduced, and the phenomenon that the system cannot treat the suddenly increased water amount and various indexes of effluent exceed standards when the water amount is maximum is caused under the condition. Meanwhile, the high-treatment-capacity supporting equipment has high energy consumption, power consumption, maintenance cost and depreciation cost in operation, namely the treatment cost per ton of water becomes high. If the earlier stage is selected to add the water collecting tank, the collected water is treated when reaching a certain amount, the required water collecting tank is very large, the volume of the larger water collecting tank also needs to be designed to be larger, and the civil engineering investment, the construction cost, the engineering construction period and the like are increased.

Disclosure of Invention

An object of the utility model is to overcome the above-mentioned problem that exists among the present sewage treatment, provide an energy-conserving formula sewage treatment system.

In order to realize the purpose of the utility model, the following technical proposal is adopted: the utility model provides an energy-conserving formula sewage treatment system, includes the catch basin, elevator pump and sewage treatment unit, sewage treatment unit have many sets of the same sewage treatment module to constitute, many sets of the same sewage treatment module set up side by side, all include anaerobism pond, good oxygen pond and MBR membrane cisterna to the back in the past in every set of sewage treatment module, all dispose independent aeration systems in every set of water treatment module, aeration systems includes air-blower and aeration diffusion equipment, aeration diffusion equipment adopt the micropore aerator, install the level gauge in the catch basin, the level gauge is connected to control system, the opening and close of each sewage treatment module of control system control.

Further, the method comprises the following steps of; the sewage treatment module adopts 5 sets, and the treatment capacity of each set of sewage treatment module is the same.

The utility model discloses an actively beneficial technological effect lies in: in the system, sewage firstly enters a collecting tank, a liquid level control system is arranged in the control system, and when the sewage inlet amount is small, the control system determines the number of the sewage treatment modules after operation according to the liquid level in the collecting tank. If the water quantity is smaller at present, one sewage treatment module can be started, when the water quantity is increased, the corresponding sewage treatment modules are started when the liquid level system detects that the liquid level reaches the corresponding liquid level, and the standby sewage treatment equipment can be provided with aeration and can supplement raw water at irregular time to increase the nutrient source, so that the system can provide a service state at any time. The system has the following two effects: firstly, the running number of the sewage treatment modules is determined according to the sewage amount, and the sewage treatment modules cannot run completely in most of time, so that the running energy consumption of matched equipment is correspondingly reduced, and the energy-saving effect can be realized; secondly, in this system, the processing of each sewage treatment module can not reduce, can deal with the state when sewage volume reaches the maximum at any time, also can guarantee that the index of going out water is qualified when sewage volume is the maximum.

Detailed Description

In order to explain the utility model more fully, the utility model provides an implementation example. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.

The invention is explained in further detail with reference to the drawings, in which the reference symbols are: 1: a water collecting tank; 2: a lift pump; 3: an anaerobic tank; 4: an aerobic tank; 5: an MBR membrane tank; 6: a blower; 7: a microporous aerator; 8: a sludge return pipe; 9: a water outlet pipe; 10: and (4) a water inlet pipe.

As shown in the attached drawings, the energy-saving sewage treatment system comprises a water collecting tank 1, wherein the water collecting tank in the application is mainly used for providing a pump placing place and a water pumping place, a lifting pump 2 and a sewage treatment unit, the sewage treatment unit comprises a plurality of sets of same sewage treatment modules, the plurality of sets of same sewage treatment modules are arranged in parallel, in the embodiment, the sewage treatment modules adopt 5 sets, and the treatment capacity of each set of sewage treatment module is the same. All include anaerobism pond 3, good oxygen pond 4 and MBR membrane cisterna 5 after to in the past in every set of sewage treatment module, sewage is handled through above-mentioned each pond after and is flowed out, and outlet pipe 9 is connected on the play water of MBR membrane cisterna, is connected with the mud back flow on the MBR membrane cisterna 5, regularly discharges mud, all disposes independent aeration systems in every set of water treatment module, and aeration systems includes air-blower 6 and aeration diffusion equipment, aeration diffusion equipment adopt micropore aerator 7, install the level gauge in the catch basin, the level gauge is connected to control system, the opening and close of each sewage treatment module of control system control.

The Henan Pingyu adopts the system to be more specific to a certain domestic sewage project example:

designing the maximum water quantity: 1500m Dimensions/d. According to the project of actual water discharge of each quarter, 5 sets of MBR membrane integrated sewage treatment modules with the treatment capacity of 300 m/d are selected.

In winter, the water discharge of the project is small, the water quantity is about 200 m/d, and the current situation requirement can be met by the system according to the liquid level of the collecting water tank, and a set of 300m sewage treatment equipment is started. The other 4 sets of equipment are all in standby state. The activated sludge is required to be ensured to have activity during normal operation in a standby state so as to ensure that the water supply amount is suddenly increased. Standby device status: intermittent aeration, replacing a portion of the water every other month, is used to provide the basic requirements of activated sludge metabolism. The water replacement mode is realized by water inlet and water discharge. In summer, the water discharge amount of the project reaches 1400 m/d. At the moment, the liquid level control judgment system provides a signal to the system, and all equipment is started to operate. The water outlet is still qualified when the water discharge reaches the maximum, the energy conservation of the power system is realized, and through comparison, the system can save more than 30 percent of energy.
