Abstract
Municipal sludge, during deep dehydration, faces pressing filtering liquid ammonia nitrogen concentration high, the problem that Treatment of Sludge workshop stench is difficult to collect and process.Devise the technology of a kind of common removal sludge press filtration ammonia nitrogen in waste water and Treatment of Sludge workshop foul smell for this, it is characterized by combine the principle of stripping, biofilter, process foul smell produced by sludge press filtration ammonia nitrogen in waste water and Treatment of Sludge workshop simultaneously.Sewage utilizes the stripping effect of workshop foul smell to remove the ammonia nitrogen of high concentration in stripping filter tank, and waste gas is entered absorption cell after stripping moistening, is removed by biological material and the absorption of microorganism, Degradation.
Description
Technical field
This utility model patent belongs to technical field of environment protection equipment, relates to the improvement of a kind of extraordinary sewage and odor treatment device technique.
Background technology
In recent years, along with the reinforcement of our municipal sewage treatment dynamics, municipal water treating capacity improves constantly, and the yield of mud is significantly increased.Showing that according to finding the mud that wastewater treatment in China factory produces has major part not obtain appropriate process, mud is arbitrarily stacked produced secondary pollution problem and has been highlighted the extensive concern having obtained society.Deeply dehydrating sludge is Treatment of Sludge extremely the key link.By dehydration, can greatly reduce the moisture content in mud, reduce the volume and weight of mud, the subsequent treatment for mud creates conditions.
Mud ammonia-nitrogen content contained by produced filter pressing waste water during dehydration is high, is not suitable for directly carrying out biochemical treatment, therefore before continuing biochemical system after entering, needs, by materialization mode, it is carried out pretreatment.Stripping is a kind of method of good reduction ammonia nitrogen, uses the mode of stripping, ammonia nitrogen in waste water can be greatly reduced, but traditional stripping exists the problem that processing cost is higher.
Mud, before carrying out deep dehydration, needs the mode using anaerobic nitrification to nurse one's health.The dewatering of mud can be improved through anaerobic nitrification, reduce the consumption of mechanical dehydration required conditioning medicament, reduce the cost of deeply dehydrating sludge.But mud can produce ' waste gas ' problem, i.e. mud during anaerobic nitrification can produce the foul gas such as ammonia nitrogen, hydrogen sulfide during carrying out anaerobic nitrification.If these gases be mustn't go to effectively, it will the environment around Treatment of Sludge factory is caused secondary pollution.Individually use foul smell to collect and treatment facility can increase again the cost in sludge handling process.
Utility model content
In order to solve the problems referred to above, this utility model patent provides the technology of a kind of common removal sludge press filtration ammonia nitrogen in waste water and Treatment of Sludge workshop foul smell.
A kind of biological stripping filter tank system, including: stripping filter tank body, centrifugal blower, water inlet pipe, air inlet pipe, wastewater effluent/circulating pump, plastic packing layer, bottom, filter tank wastewater disposal basin, wastewater effluent/circulation pipe, stripping filter tank air vent, absorption cell body, absorption cell draining pump, absorption cell air vent, absorption cell biomass filler, centrifugal blower air inlet pipe, inspection socket Treatment of Sludge workshop, described stripping filter tank body is arranged side by side with absorption cell body, and connected by stripping filter tank air vent, described centrifugal blower connects air inlet pipe, described water inlet pipe connect wastewater effluent/circulating pump and wastewater effluent/circulation pipe and centrifugal blower thus the ammonia nitrogen part that reaches in waste water with the form of ammonia by stripping out, and entered in absorption cell body by stripping filter tank air vent.
Described stripping filter tank air vent is less than the liquid level of absorption cell body.
Absorption cell air vent is arranged at absorption cell bodies top.
Absorption cell body interior sets gradually absorption cell air vent, absorption cell draining pump and absorption cell biomass filler from top to bottom.
Filter pressing waste water is entered in filter tank by the water inlet pipe on the top in biological stripping filter tank by this utility model, contact with gas at packing layer, with the form of ammonia by stripping out, the metabolic effect of the microorganism during the ammonia nitrogen in waste water also has part filled simultaneously is consumed an ammonia nitrogen part in waste water；Bottom, filter tank is provided with circulating pump, waste water can be circulated process, requires until reaching subsequent treatment.
The effect by blower fan of the foul smell in Treatment of Sludge workshop, for the stripping of filter pressing waste water.The waste gas produced during whole, enters absorption cell by the air vent in stripping filter tank, is provided with biomass filler in absorption cell, and the waste gas containing high strength ammonia, after the moistening of stripping pond, is adsorbed bio-absorbable pond is filled, and is finally utilized by the microorganism.Gas after process, through absorption cell air vent qualified discharge.
I.e. through anaerobic treatment filter pressing waste water by regulation pH to 10 after enter biological stripping filter tank and process, top, filter tank sewage is by jet pipe entrance stripping filter tank.The packing layer being made up of hollow plastics many-sided ball it is provided with, to improve the contact area of waste water and waste gas in the middle of trickling filter.It is provided with distribution device below filler, foul smell can be introduced below filler packing layer and carry out synchronization process；In stripping filter tank, the surface of packing layer can utilize the metabolism of microorganism, getting rid of the degradability pollutant in sewage and foul smell, and this used time, sludge press filtration liquid contacts with gas cross-flow, ammonia nitrogen in sewage also can be converted into the form of gas, be collected processing hence into subsequent absorption pond；Stripping filter tank air inlet connects Treatment of Sludge workshop, uses centrifugal blower to carry out negative pressure convulsion, thus the foul smell processing workshop is introduced biological stripping filter tank, reach the purpose simultaneously processing waste water with waste gas.Being provided with reflux pump below filter tank, the sewage backflow after be able to processing by the way of backflow is to top water inlet pipe, to improve the efficiency of sewage disposal.
This utility model feature:
1, use a kind of device that sludge press filtration ammonia nitrogen in waste water and Treatment of Sludge workshop foul smell are carried out synchronization process；
2, use centrifugal blower negative pressure convulsion, reach workshop foul smell simultaneously and collect, with the purpose of stripping filter tank aeration；
3, with individually employing stripping process process waste water is compared with biological filtering tank process process waste gas, device capital cost is low for this, save equipment and operating cost, reliable, it is simple to management.
