Abstract

The invention relates to cold area sewage cold and heat source sewage heating process device. It includes heat pump assembly, processed sewage intake pipe, processed sewage outlet pipe, unprocessed sewage intake pipe, unprocessed sewage outlet pipe, intake end of evaporator, outlet of evaporator, and the outlet of condenser. The invention uses heat pump to distilling the heat quantity from purified water after processed by effluent treatment plant to transmit to the city sewage that needs to be processed by sewage biochemical treatment plant. The invention not only solves the antinomy between distilling the cold area sewage heat energy and sewage biochemical treatment temperature, but also solves the low temperature of sewage biochemical process itself.

Description

The cold district sewage cold-hot source sewage accompaning thermal treatment unit
Technical field
The municipal effluent that the present invention relates to have handled heats the device that the former water (municipal effluent is untreated) of biochemical treatment is carried out in preparation as the heat pump Cooling and Heat Source.
Background technology
Develop all kinds of low level recyclability clean energies, have important energy saving and environment protection significance.Municipal effluent is one of low-phase energy, it comprises former water and sewage work's sewage of municipal wastewater pipe network, be the largest portion of city waste heat discharge amount, develop municipal effluent is one of effective measure of alleviating energy consumption and problem of environmental pollution effective and reasonablely.Municipal effluent is other Cooling and Heat Source relatively, and the big characteristics of fine quality of the amount of having are estimated 2010, and China's quantity of wastewater effluent will reach 72,000,000,000 m 3, can be to the air conditioning and heating of 20% buildings by the sewage heat energy that heat pump techniques reclaims.Sewage temperature is suitable simultaneously, between 10 ℃~25 ℃, is fit to Winter-summer dual purpose throughout the year, is the good low level Cooling and Heat Source of heat pump, and exploitation prospect is wide.
But the low temperature problem of the extraction of severe cold area sewage heat energy and sewage biochemical treatment is a pair of insoluble contradiction.Severe cold area sewage water temperature is relatively low, if the sewage water temperature is low excessively in the biochemical treatment process, sludge bulking, aeration tank can occurs and problem such as freeze, and water treatment efficiency will reduce, sewage load with handle after water quality be difficult to guarantee.Have to take insulation, heating to improve measures such as former water water temperature for this reason.If the heat energy before the sewage disposal is further developed extraction, certainly will will increase the weight of the seriousness of low temperature problem.
Summary of the invention
The purpose of this invention is to provide a kind of cold district sewage cold-hot source sewage accompaning thermal treatment unit, with the extraction of solution cold district sewage heat energy and the contradiction between the sewage biochemical treatment temperature.The cold district sewage cold-hot source sewage accompaning thermal treatment unit, it comprises heat pump set 1, dispose of sewage into pipe 4, the comb 5 of having disposed of sewage, untreated sewage are gone into pipe 6 and untreated sewage comb 7, disposed of sewage and be communicated with the input terminus of the vaporizer 1-1 of heat pump set 1 into pipe 4, the comb 5 of having disposed of sewage is communicated with the output terminal of vaporizer 1-1, untreated sewage is gone into the input terminus that pipe 6 is communicated with the condenser 1-2 of heat pump set 1, and untreated sewage comb 7 is communicated with the output terminal of the condenser 1-2 of heat pump set 1.Device of the present invention utilizes heat pump set 1 that the heat extraction that is treated as in the water of clean water by sewage work is come out, pass to the municipal effluent of preparation by sewage biochemical treatment factory and office reason, before sewage disposal, do not carry out energy recovery, to avoid the water temp in the biochemical processing procedure of sewage too low, after sewage disposal, this moment the heat extraction in the sewage come out to be used for sewage before the heat treated, improve former water water temperature to reach minimum or best biological existence condition, thereby the quality and the efficient of water treatment procedure have been guaranteed, device of the present invention had both solved the extraction of cold district sewage heat energy and the contradiction between the sewage biochemical treatment temperature, had solved the low temperature problem of sewage biochemical treatment itself again.
