Description
Technical field
This application involves a kind of chemicals dosing plant, especially a kind of mobile sewage disposal device chemicals dosing plant.
Background technology
City domestic sewage discharge at present has been the primary pollution source of Chinese city water, and city domestic sewage processing is current
The most important thing of urban water conservation from now on and treatment work, this requires us processing sanitary sewage facility
Construction grabbed as the important content of urban infrastructure, and be too impatient to wait thing.
Sewage disposal is to handle the significant process of water pollution.Using the method for physics, biology and chemistry to industrial wastewater and
Sanitary sewage is handled to detach the solid pollutant in water and reduce the organic pollution in water and nutrient rich（Predominantly
Nitrogen, phosphorus compound）, to mitigate pollution of the sewage to environment.
Before sewage disposal, generally require to sewage carry out dosing pretreatment, such as be added NaClO, by sewage bacterium,
The removals such as microorganism prevent damage of the bacterium to subsequent filter film；Sensitizer is added in favor of microwave reaction etc..
Currently, chemicals dosing plant generally including pond of making up a prescription, medicine storage pool, drug mixing pit, metering pump and matches circuits, valve
Deng and the part that must be equipped with of all chemicals dosing plants.Wherein, metering pump is the most key part.In Practical Project,
Often generate the case where being had an impact to entire dosing because of metering pump type selecting inaccuracy.Metering pump is frequently with mechanical diaphragm
Pump, it is a kind of positive displacement pump causing volume variation by diaphragm reciprocal transformation using compressed air as power, and operation principle is similar to
Plunger pump.Basic parameter includes flow and lift.On the nameplate of metering pump, often it can be seen that metering pump is with very wide
The personnel of abundant range of choice, plant design water supply-drainage discipline also can usually provide such as 0~200 L/h, 0~400 L/h
Type selecting parameter, but actually metering pump also has its optimum condition, if actual flow deviates from optimum condition, the flow of metering pump
It is in fact also just inaccurate.According to live practical experience, the best aperture of metering pump is 50%, i.e., when working flow is metering
When pumping the half of maximum stream flow, metering pump is in optimum Working, and working flow is too big or too small, and flow value is inaccurate,
Dosage will be caused inaccurate.
According to the requirement of Law on Environmental Protection Laws ＆ Regulations, trade effluent generates unit and needs mating setting sewage disposal device.
For most industrial production enterprises, fixed sewage disposal is set generally according to the situation of dirt contained by specific sewage
Equipment.The advantages of fixed sewage disposal device is can be arranged as required to sewage-treatment plant, without by space size
Limitation.
However, in many cases it is required the water pollution situation to some bursts carries out emergency processing, such as Songhua River Pollution
Event and the sewage tracheal rupture etc. of enterprise's burst.This kind of situation is needed a kind of removable due to time, the uncertainty in place
The sewage disposal device of dynamic formula, timely to be handled sewage at first time arrival event scene.For this purpose, existing skill
Various corresponding sewage disposal devices have been proposed in art.
Application No. is 200420099630.0 Chinese utility model patent, invention wounds disclosed in 25 days January in 2006
Entitled " a kind of vehicle-mounted sewage treating equipment " made, the equipment use vehicle-mounted box type structure, collection adsorb, flocculate, falling to
One, front equipment end symmetrically set two medicine storage pools, medicine storage pool lower part establishing medicine pond；Switch board is set between two medicine storage pools, under switch board
Portion is installed by high pressure air pump and magnetic force driving pump;Equipment front sets drug mixing pool, and drug mixing pool side sets original water inlet, and it is heavy to be set in the middle part of equipment
Shallow lake pond, sedimentation basin top set catch basin, and tube settler is installed at middle part, and equipment rear end sets sand filter, quartz is set in the middle part of sand filter
The filter layer of layer of sand and metalling composition, water outlet are located at sand filter upper rear end;Drug mixing pool, sedimentation basin, sand filter bottom are equal
Bottom is bored equipped with each spoil disposal of spoil disposal cone bottom spoil disposals manifold connections, constitutes spoil disposal channel.
Above-mentioned vehicle-mounted sewage treating equipment has following insufficient：
1. when to raw water dosing, be set up in parallel in vehicle-mounted box type structure sufficiently bulky pond of making up a prescription, medicine storage pool and
Drug mixing pool.These structures will occupy vehicle-mounted a big chunk volume, not meet the requirement of vehicle-mounted size.
2. each drug is added metering and fixes, dosing cannot be carried out 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 which impurity, microorganism in raw water etc. is all clear
Except clean, sewage disposal index will be caused not up to standard, sedimentation filtration process in road after inflow.
b）When raw water flow is small, add the medicament of fixed amount, at this moment, pharmaceutical quantities will be added excessive, it will cause to
Raw water brings new pollution, subsequently also needs the device or step that increase removal medicament.
Application No. is 200810084959.2 Chinese invention patent, the names of innovation and creation disclosed in 6 days for August in 2008
Referred to as " mobile sewage treatment apparatus ".
Above-mentioned patent application, including a delivery vehicle, be placed on the delivery vehicle microwave sewage processing system,
The sedimentation filtration in the downstream of the microwave reactor, being connected with the outlet of sewer of the microwave reactor by pipeline is set
Device, and the sensitizer being arranged in the upstream of the microwave reactor and other water treatment agent adding sets.
The front wheels in the sedimentation filtration device other end are arranged in above-mentioned sensitizer and other water treatment agent adding sets
On platform or trailing wheel group platform.The sensitizer and other water treatment agent adding sets include a hybrid reaction chamber, and described
The sensitizer explosive box that mixing reactor is connected, and for other additions to be added to being added in the sewage of the sensitizer
Other additive explosive boxs of agent；Blender is set in the mixing reactor.
Above-mentioned mixing reactor is connected to the sensitizer explosive box by a delivery pipe with metering pump;It is described its
Other add is added to being added in the sewage of the sensitizer by a delivery pipe with metering pump in its additive explosive box
Add agent.It is also equipped with blender in the sensitizer explosive box.In the mixing reactor and the sensitizer explosive box
The blender in gas blender is gas blender, and shares a gas pipeline.
Above-mentioned mobile sewage treatment apparatus, it is uniform to solve existing microwave sewage processing system dosing, and microwave utilizes
The low technical problem of rate.But there are still following deficiencies：
1. when to raw water dosing, in delivery vehicle, as being still provided with multiple sensitizers and other water treatment agents on car body
Adding set and hybrid reaction chamber.These structures will also occupy vehicle-mounted a big chunk volume, not meet vehicle-mounted size
It is required that.
2. each drug is added metering and still fixes, still dosing cannot be carried out according to the actual flow of sewage.Still it deposits
Underdosage is added in drug or excessive problem is added.
