Fig. 1 is the structural representation of microorganism active temperature controlling system in the utility model sewage treatment process.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Microorganism active temperature controlling system in a kind of sewage treatment process as described in Figure 1, mainly provides heat energy by shell and tube heat exchanger for whole sewage treatment process.Described shell and tube heat exchanger comprises the intake ducting of a hollow, and between the inwall of shell and tube heat exchanger and the outer wall of intake ducting, forms the inlet channel of a circle periphery.As shown in Figure 2, the cross section of shell and tube heat exchanger forms a concentrically ringed shape, and middle part is the intake ducting into steam condensate, and the inlet channel of waste water is entered in periphery.Two fluid streams form convective heat exchange, and it is shell side 20 that peripheral inlet channel enters waste water, and it is tube side 10 that the gas pipeline at middle part enters steam condensate.The one recycling of condensed steam main pipeline of collecting water of condensation connect shell and tube heat exchanger tube side 10 enter the steam mouth of pipe 11, the steam mouth of pipe 12 that goes out of tube side 10 is communicated with a water of condensation cooling tank; One equalizing tank that catchments of collecting sewage plant waste water is delivered to waste water by a lift pump water inlet pipe mouth 21 of the shell side 20 of shell and tube heat exchanger, and the effluent pipe mouth 22 of shell side 20 is communicated with anaerobic pond.
The water of condensation that each workshop process section produces while using steam, after vapor condensation is in charge of collection, import recycling of condensed steam main pipeline, to enter the outer fluid channel forming of shell and tube heat exchanger be tube side 10 to the steam mouth of pipe 11 that enters of the tube side 10 of water of condensation by shell and tube heat exchanger.
In sewage plant with catchment and be provided with a hydraulicefficiency machinery sieve between equalizing tank, enter the waste water that first waste water of sewage plant sieve entering sewage plant by hydraulicefficiency machinery and carry out impurity screening, clear liquid after filtration all imports the equalizing tank that catchments, then lift pump by being arranged on the equalizing tank bottom of catchmenting water inlet pipe mouth 21 that waste water is delivered to the shell side 20 of shell and tube heat exchanger to enter the fluid channel forming in shell and tube heat exchanger be shell side 20.When shell side 20 and tube side 10 are respectively when the fluid by two kinds of differing tempss, the steam condensate that temperature is higher transfers heat to the waste water that temperature is lower, so that the higher steam condensate of temperature is cooled, and the lower waste water of temperature is heated, thereby has realized heat exchange.After steam condensate is cooled, the steam mouth of pipe 12 that goes out of the tube side 10 by shell and tube heat exchanger drains into water of condensation cooling tank by the steam condensate after heat exchange through discharge tube and carries out further cooling down.The heated waste water effluent pipe mouth 22 of the shell side 20 by shell and tube heat exchanger enters into anaerobic pond through discharge tube, thereby realizes microorganism active temperature control in sewage treatment process.
The hot steam that the utility model utilizes each workshop explained hereafter to use, because hot steam in use can produce water of condensation, its temperature generally can reach 70 DEG C-80 DEG C, and in the anaerobic technique section of sewage treatment process, temperature has a significant effect to organic loading in anaerobic pond and gas production rate.Adaptability according to microorganism to temperature, in anaerobic pond, microorganism active becomes to increase progressively in 20 DEG C-40 DEG C, and in sewage, Pollutant Treatment rate is the highest, anaerobism best results.Because temperature is lower larger on microbic activity impact in anaerobic pond, reduced the processing efficiency of microorganism winter.For above-mentioned water of condensation and the characteristic of microorganism in oxygen pond too, the utility model is collected condensed hot water by recycling of condensed steam main pipeline, and adopt shell and tube heat exchanger to be used for adding thermal wastewater, thereby microorganism active temperature in control sewage treatment process, improve a kind of technology of microorganism active, it can improve microbiological treatment efficiency in anaerobic pond, also can ensure the steady running of sewage process treatment process simultaneously.
Above-mentioned explanation illustrates and has described preferred embodiment of the present utility model, as previously mentioned, be to be understood that the utility model is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, amendment and environment, and can, in utility model contemplated scope described herein, change by technology or the knowledge of above-mentioned instruction or association area.And the change that those skilled in the art carry out and variation do not depart from spirit and scope of the present utility model, all should be in the protection domain of the utility model claims.
