3, H
2s, utilizes the ozone with oxygenizement can also remove stink in mud.Ozone reacts with the gas producing stink, thus makes it oxidizing reaction occur and decompose, and after oxidizing reaction, material can be separated and discharged by the water in sludge handling process.Because the effect of the pressurization in reactor makes the mixing between ozone and the gas of various generation foul smell, contacts more fully, thus improve the effect of foul smell.The cyclical operation of high pressure and low pressure, can change liquid level tension force and the content of ozone in liquid is increased, the organism in mud etc. increase with the touch opportunity of ozone, react more abundant.In the present embodiment, in the mixed gas of ozone and air, the volumetric concentration of ozone is 50%, and the force value of high pressure conditions is 0.3MPa (MPa), and constant voltage time is 20s, and low-pressure state is 1 standard atmospheric pressure, and loop cycle is 8 times.
Further, in order to improve the treatment effect of sludge reaction unit, sludge reaction unit also comprises agitator motor and agitator.Agitator comprises stir shaft and is arranged at the scraper plate of stir shaft one end, and agitator motor is arranged at outside reactor 104, and stir shaft is arranged along the axis of reactor 104, and scraper plate is positioned at reactor 104, and stir shaft is connected with the rotating shaft of agitator motor away from one end of scraper plate.Mud in reactor 104 can stir by agitator, makes the contact of mud and ozone more abundant, when chemical reagent is imported in reactor 104, chemical reagent also can be made to contact with mud more abundant, thus make reaction more thorough.
Mud after above-mentioned process is directed to mud postpositive disposal unit subsequently, is separated with liquid the solid in mud.Sludge reaction unit makes heavy metal to react with chemical reagent and coagulation occurs, microorganism due to microbial film, the destruction of such as cytolemma and dead, thus carry out filtering separation by the first solid-liquid separator 105.Preferably, the first solid-liquid separator 105 adopts high green whizzer.
Due to the regulation and control relating to high pressure and low pressure in the sludge treating system that the present embodiment provides, if directly by Artificial Control, then operate inconvenience and may mishandle be produced, affecting normal sludge treatment.For above-mentioned situation, sludge treating system also comprises the housing being provided with PLC parametric controller, and PLC parametric controller is connected with pressure-regulator 103, realizes setting concrete operation steps by PLC parametric controller, the i.e. concrete numerical value of high pressure, low pressure, the high pressure carried out, low voltage operated number of times.So, the adjustment of pressure is more accurate, timely, makes sludge treatment more efficient.Preferably, PLC parametric controller also comprises terminal, and terminal is provided with human-computer interaction interface, by human-computer interaction interface can make operator convenient, operate quickly.Operator can carry out touch operation by human-computer interaction interface, and also can pass through peripheral hardware, such as mouse, keyboard operate on it.Further, PLC parametric controller is also provided with the hummer sending guard signal, and sludge reaction unit also comprises pressure transmitter, and pressure transmitter is arranged on reactor 104, and pressure transmitter is electrically connected with PLC parametric controller.When after the pressure that pressure transmitter detects in reactor 104, feed back to PLC parametric controller in real time, then be above safe pressure value by judgement or lower than service pressure value thus in time to pressure controlling.
Preferably, sludge treating system also comprises sewage recovery unit, in order to reclaim the water through producing sludge treatment.Sewage recovery unit comprises recovery pump 106, withdrawing can and the second solid-liquid separator 107.Recovery pump 106 is provided with recovery pump 106 opening for feed and recovery pump 106 discharge port, and the second solid-liquid separator 107 is provided with the second separate inlet opening and is separated outlet with second, and withdrawing can is provided with withdrawing can import and withdrawing can outlet.Recovery pump 106 opening for feed is separated outlet with first, and recovery pump 106 discharge port is communicated with the second separate inlet opening, and second is separated outlet and withdrawing can inlet communication.Be separated by mud postpositive disposal unit the sewage produced and inject the second solid-liquid separator 107 by recovery pump 106, after being separated by the second solid-liquid separator 107, liquid enters withdrawing can and stores.Mud then can carry out dewatering again, dry discharge, or is used as compost.Can also flocculation agent be added in second solid-liquid separator 107, to make in sewage the not easily precipitated species precipitate with being separated, and then filter, thus quality, the reduction pollution of sewage can be improved.
Owing to needing in this sludge treating system to use water, can the water reclaimed be utilized again.Thus, sewage recovery unit also comprises recycle pump, and recycle pump is provided with Ethylene recov import and Ethylene recov outlet, Ethylene recov import and withdrawing can outlet, and Ethylene recov outlet is connected with treatment channel.Sewage in withdrawing can pumps and injects sewage sludge storage tank 101, in order to increase the mobility of mud or can be used for cleaning each equipment by recycle pump.
