Abstract
The utility model relates to an activated sludge process treatment system for automatically adjusting dissolved oxygen content, comprising a blower fan, an aeration tank and a secondary sedimentation tank, wherein the blower fan is connected with the aeration tank through an air pipeline on which a valve is mounted; and the aeration tank is connected with the secondary sedimentation tank through a muddy water pipeline. The activated sludge process treatment system for automatically adjusting dissolved oxygen content is characterized in that the secondary sedimentation tank is internally provided with an on-line dissolved oxygen measurement instrument which is connected with one end of a frequency converter through a line, and the other end of the frequency converter is connected with a motor of the blower fan through a line; and data of dissolved oxygen in the secondary sedimentation tank are transmitted to the frequency converter for controlling the running of the motor of the blower fan at any time through the on-line dissolved oxygen measurement instrument in the secondary sedimentation tank, and the rotation speed of the blower fan is adjusted through the frequency converter according to the content of the dissolved oxygen, thereby guaranteeing the relative stable content of the dissolved oxygen in the system, avoiding the unfavorable influence of excess aeration on a biochemical system, improving the running effect of wastewater treatment and simultaneously reducing the electric energy cost expenditure of wastewater treatment and saving energy source.
Description
Technical field
The utility model relates to the Wastewater Treated by Activated Sludge Process system that dissolved oxygen content is regulated in a kind of automatic control.
Background technology
In the chemical field, usually adopt conventional activated sludge process that waste water is carried out aerobic treatment.Because inevitable fluctuation in the production process, the concentration of substrate of waste water changes obviously, and the height of concentration of substrate directly influences the consumption of dissolved oxygen.When concentration of substrate is on the low side, occur excessive aeration phenomenon easily, influence effluent quality, and cause the waste of the energy.Gas blower is one of key equipment that guarantees the normal operation of sewage disposal, but gas blower also is the main energy consumption equipment in biochemical workshop, and power consumption accounts for about 50% of entire sewage processing cost, is unfavorable for energy-conservation.
Summary of the invention
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the Wastewater Treated by Activated Sludge Process system that provide a kind of and can adjust blower speed according to the size of dissolved oxygen, prevent excessive aeration, save energy, the automatic control that reduces cost is regulated dissolved oxygen content.
The technical scheme that its technical problem that solves the utility model adopts is: the Wastewater Treated by Activated Sludge Process system of dissolved oxygen content is regulated in a kind of automatic control, comprise gas blower, aeration tank and second pond, gas blower connects the aeration tank by airline, mounted valve on the airline, the aeration tank connects second pond by the muddy water pipeline, it is characterized in that: be provided with online dissolved oxygen sensing instrument in the second pond, online dissolved oxygen sensing instrument connects frequency transformer one end by circuit, and the frequency transformer the other end connects the motor of gas blower by circuit.
By about 10cm place under the liquid level surface in the biochemical system second pond online dissolved oxygen meter is installed, the data of dissolved oxygen can be transferred on the frequency transformer of control blower motor operation at any time in the second pond, adjust blower speed by frequency transformer according to the size of dissolved oxygen, thereby dissolved oxygen is steady relatively in the energy assurance system, improved the operating performance of sewage disposal, reduce the phenomenon that causes treat effluent to exceed standard because of excessive aeration, reduced cost of electric energy expenditure, the save energy of sewage disposal simultaneously.
The beneficial effect that the utility model had is: provide a kind of automatic control to regulate the Wastewater Treated by Activated Sludge Process system of dissolved oxygen content, at any time be transferred on the frequency transformer of control blower motor operation by the data of the online dissolved oxygen meter in the second pond dissolved oxygen in the second pond, and by the size adjustment blower speed of frequency transformer according to dissolved oxygen, guaranteed the steady relatively of dissolved oxygen in the system, prevent the disadvantageous effect of excessive aeration to biochemical system, improve the operating performance of sewage disposal, reduced cost of electric energy expenditure, the save energy of sewage disposal simultaneously.
