Description
Technical field
The application relates to a kind of adding method thereof, particularly a kind of mobile sewage disposal device adding method thereof.
Background technology
The discharge of current city domestic sewage has been the primary pollution source of Chinese city water; city domestic sewage processes the most important thing being urban water conservation at present and in the future and treatment work; this just requires that we to grab the important content as urban infrastructure of building processing sanitary sewage facility, and is too impatient to wait thing.
Sewage disposal is to process the significant process that water pollutes.Adopt physics, solid pollutant that industrial wastewater and sanitary sewage are processed to separate in water by the method for biology and chemistry the organic pollution reducing in water and nutrient rich (being mainly nitrogen, phosphorus compound), thus alleviating the sewage pollution to environment.
Before sewage disposal, it is generally required to sewage is carried out dosing pretreatment, as added NaClO, so that the antibacterial in sewage, microorganism etc. are removed, it is prevented that the antibacterial damage to subsequent filter film；Add sensitizer and be beneficial to microwave reaction etc..
At present, chemicals dosing plant generally includes make up a prescription pond, medicine storage pool, medicament mixed pond, dosing pump and supporting pipeline, valve etc., is also the part that must be equipped with of all chemicals dosing plants.Wherein, dosing pump is the most key part.In Practical Project, the situation often producing because dosing pump type selecting is inaccurate, whole dosing to be produced impact occurs.Dosing pump is frequently with Machinery Diaphragm Pump, and it, to compress air for power, is a kind of displacement pump being caused volume to change by diaphragm reciprocal transformation, and operation principle is similar to plunger displacement pump.Basic parameter includes flow and lift.On the nameplate of dosing pump; often it can be seen that dosing pump has the very well-to-do range of choice; the personnel of plant design water supply-drainage discipline also usually can provide the type selecting parameter of such as 0～200L/h, 0～400L/h; but actually dosing pump also has its optimum condition; actual flow is if the deviation from optimum condition, and the flow of dosing pump is in fact also just inaccurate.According to on-the-spot practical experience, the best aperture of dosing pump is 50%, and namely when the half that working flow is dosing pump maximum stream flow, dosing pump is in optimum Working, and working flow is too big or too little, and its flow value is all inaccurate, it will cause that chemical feeding quantity is all inaccurate.
Requirement according to Law on Environmental Protection Laws & Regulations, trade effluent generation unit needs are supporting arranges sewage disposal device.For most commercial production enterprises, the situation generally according to dirt contained by concrete sewage arranges fixing sewage disposal device.The advantage of fixed sewage disposal device is to be arranged as required to sewage-treatment plant, and not by the restriction of space size.
But, in many cases it is required the water pollution condition of some bursts is carried out emergency processing, the soil pipe happened suddenly such as Songhua River Pollution event and enterprise breaks.This kind of situation, due to the uncertainty of time, place, it is necessary to a kind of portable sewage disposal device, in order at very first time arrival event scene, sewage is processed timely.For this, prior art has been proposed for various corresponding sewage disposal device.
Application number disclosed in 25 days January in 2006 is the Chinese utility model patent of 200420099630.0, the name of its innovation and creation is called " a kind of vehicle-mounted sewage treating equipment ", this equipment adopts vehicle-mounted box type structure, collection adsorbs, flocculates, falls to one, front equipment end symmetry sets two medicine storage pools, medicine storage pool bottom establishing medicine pond；Setting switch board between two medicine storage pools, high pressure air pump and magnetic force driving pump are installed in switch board bottom;Equipment front portion sets drug mixing pool, and drug mixing pool side sets original water inlet, sets sedimentation tank in the middle part of equipment, sedimentation tank top sets water leg, and tube settler is installed at middle part, and equipment rear end sets sand filter, setting quartz sand layer and the filter course of metalling composition in the middle part of sand filter, outlet is located at sand filter upper rear end;The spoil disposal cone end it is equipped with bottom drug mixing pool, sedimentation tank, sand filter. spoil disposal house steward connects each spoil disposal cone end, constitutes spoil disposal passage.
Above-mentioned vehicle-mounted sewage treating equipment, has following deficiency:
1., when to former water dosing, vehicle-mounted box type structure has been set up in parallel sufficiently bulky pond of making up a prescription, medicine storage pool and drug mixing pool.These structures will take vehicle-mounted a big chunk volume, not meet the requirement of vehicle-mounted size.
2. medicine addition metering is fixing every time, it is impossible to carry out dosing according to the actual flow of sewage.
A) when raw water flow is big, the medicament of fixed amount is added, it is impossible to the impurity in former water, microorganism etc. are all removed clean, sewage disposal index will be caused not up to standard, sedimentation filtration operation in road after inflow.
B) when raw water flow is little, adding the medicament of fixed amount, at this moment, pharmaceutical quantities will add too much, it will causing bringing new pollution to former water, follow-up also need increases the device removing medicament or step.
Application number disclosed in 6 days Augusts in 2008 is the Chinese invention patent of 200810084959.2, and the name of its innovation and creation is called " mobile sewage treatment apparatus ".
Above-mentioned patent application, process system including a vehicle, the microwave sewage that is placed on described vehicle, be arranged on the downstream of described microwave reactor, by the sedimentation filtration device that the outlet of sewer of pipeline with described microwave reactor is connected, and it is arranged on the sensitizer in the upstream of described microwave reactor and other water treatment agent adding set.
Above-mentioned sensitizer and other water treatment agent adding set are arranged on front-wheel group platform or the trailing wheel group platform of the described sedimentation filtration device other end.Described sensitizer and other water treatment agent adding set include a hybrid reaction chamber, the sensitizer explosive box being connected with described mixing reactor, and for adding other additive explosive box of other additive in the sewage with the addition of described sensitizer；Described mixing reactor arranges agitator.
Above-mentioned mixing reactor is connected with the conveying pipe of dosing pump by one with described sensitizer explosive box;Other additive explosive box described adds other additive by a conveying pipe with dosing pump in the sewage with the addition of described sensitizer.Described sensitizer explosive box is also equipped with agitator.Described mixing reactor and the described agitator in the gas blender in described sensitizer explosive box are gas blender, and share a gas pipeline.
Above-mentioned mobile sewage treatment apparatus, solves existing microwave sewage and processes system dosing uniformly, and the technical problem that microwave utilization rate is low.But still there is following deficiency:
1. when to former water dosing, at vehicle, as car body is still provided with multiple sensitizer and other water treatment agent adding set, and hybrid reaction chamber.These structures also will take vehicle-mounted a big chunk volume, not meet the requirement of vehicle-mounted size.
2. medicine addition metering is still fixed every time, still can not carry out dosing according to the actual flow of sewage.Yet suffer from medicine add underdosage or add too much problem.
