Description
Technical field
The invention belongs to chemical enterprise accident wastewater collection technical field, especially a kind of collection storage method of chemical workshop fire incident waste water.
Background technology
The early stage each chemical workshop be constructed and put into operation as Xiamen at south China, because present situations such as limited space, plant area are shaping, network of underground is complicated, the Environment Pollution Event caused by fire incident takes place frequently, therefore prevent fire incident waste water from arranging outward and cause this area's environment pollution to become an important process of accident emergency rescue, and perfect fire incident wastewater collection Response project also more and more draws attention.
The floor space of usual chemical workshop and the gross weight of transfer every day chemicals are given; the tank car storing transfer chemicals is configured with in chemical workshop; several indoor fire-fighting hydraulic giant is configured with in chemical workshop; several outdoor fire fighting hydraulic giant is configured with outside chemical workshop; described indoor fire-fighting hydraulic giant and described outdoor fire fighting hydraulic giant go out the regulation that water inventory meets GB50016-2006 in fire incident Fire Fighting Time 3.0 hours, and the maximum average rainfall of chemical workshop residingly in fire incident Fire Fighting Time 3.0 hours is estimated as Tmm.
Does is problem: how to process according to the existence conditions of chemical workshop the environment pollution caused due to fire incident? which type of takes collect storing mode to the fire incident waste water of chemical workshop comparatively reasonable? about the collection storage method of this respect yet there are no relevant report.
Summary of the invention
For solving the problem; the invention provides a kind of collection storage method of chemical workshop fire incident waste water; this collection storage method is by the peak discharge of calculating accident waste water; by building cofferdam, chemical workshop gate and building liquid collecting hole; both the collection requirement of fire incident waste water had been met; also for the final discharge of fire incident waste water lays the foundation, reach the production environment of protection chemical workshop preferably, prevent the object causing secondary environment contaminated because fire incident waste water expands.
For achieving the above object, the present invention adopts following technical scheme:
A collection storage method for chemical workshop fire incident waste water, relates to the floor space S m of given chemical workshop in this collection method of disposal
2, given transfer every day chemicals gross weight be W ton, several indoor fire-fighting hydraulic giant is configured with in chemical workshop, outside chemical workshop, be configured with several outdoor fire fighting hydraulic giant, described indoor fire-fighting hydraulic giant and the described outdoor fire fighting hydraulic giant water inventory that goes out in fire incident Fire Fighting Time 3.0 hours is L m
3, L m
3meet the regulation of GB50016-2006, the maximum average rainfall of chemical workshop residingly in fire incident Fire Fighting Time 3.0 hours is estimated as Tmm; This collection method of disposal also uses waste collection pipeline, control valve, liquid collecting hole, float valve, anti-explosion submersible pump, switch board, flexible pipe, content gauge, leakage fluid dram, fire incident waste water comprise described transfer chemicals, described in go out water inventory L and described amount of precipitation, feature of the present invention is as follows:
The storage tank that can store the heavy transfer chemicals of W ton is located on the horizontal base at the outer arbitrary place of chemical workshop, liquid collecting hole is set between storage tank and chemical workshop, storage tank arbitrary side configuration content gauge and configuration level leakage fluid dram bottom it, anti-explosion submersible pump is arranged on bottom, liquid collecting hole, the flexible pipe of drawing from storage tank upper end connects with anti-explosion submersible pump, anti-explosion submersible pump realizes opening or closing down by switch board, float valve is set in liquid collecting hole and hole lid is set in upper end, liquid collecting hole, waste collection pipeline is configured in chemical workshop, waste collection pipeline is extended in liquid collecting hole, the waste collection pipeline of extending arranges control valve, chemical workshop gate place is provided with the cofferdam of H height, the cofferdam of H height makes the concentrated reservoir forming fire incident waste water in chemical workshop, the summation volume of adding liquid collecting hole and storage tank just can be implemented effectively to collect and store to fire incident waste water, can also be cheated by liquid collecting while described concentrated reservoir carries out collecting storage and directly pump into tank car and transfer to the unit of qualification to carry out harmless treatment, finally reach and prevent the not outer row of fire incident waste water, object free from environmental pollution,
Above-mentioned H will draw according to the maximum estimator M of fire incident waste water, the maximum estimator M=N+L+E of fire incident waste water, in this formula:
N is the estimation volume amounting to rear transfer chemicals, if W is ton weight, then and W ≈ Nm
3;
E is the estimation volume m of rainwater
3if the maximum average rainfall in fire incident Fire Fighting Time 3.0 hours is estimated as T=40mm, then E=S × T, notice that the unit of T will be converted to m from mm;
Then H=M/S.
Volume>=2 m in above-mentioned liquid collecting hole
3, liquid collecting hole exceeds terrace benchmark and adopts concrete structure, and the inwall in liquid collecting hole is through Anti-seeping technology.
Waste collection pipeline adopts stainless-steel pipe, whitewashes anticorrosive paint at the outer wall of described stainless-steel pipe, re-uses brick, concrete is built groove and wrapped up by described stainless-steel pipe.
Storage tank adopts PE material to be made, and cause storage tank impaired with the amount of heat discharged during fire-proof, storage tank can make fire incident waste water be convenient to layering and process in storage process.
Owing to adopting technical scheme described above, the present invention produces following good effect:
1, the cofferdam that the present invention is provided with H height solves on the one hand wastewater collection storage problem under fire incident and the environmental requirement met outside chemical workshop, solving early stage chemical workshop emergency service does not match perfect problem on the other hand, has greatly saved and has built up this again.
2, the present invention can solve the wastewater collection storage problem under fire incident state effectively, thus under enclosed environment not effluent stream rush down, operating process is simple and easy and practical, thus reaches the object of protection of the environment.
3, the cofferdam being provided with H height serves Sources controlling effect in fire incident wastewater collection storage process, and construction cost of the present invention is low, and to construction, comparatively morning, the incomplete chemical workshop of environmental emergency Facilities serialized have reference value.
4, liquid collecting hole, storage tank have certain volume, play storage effect to the fire incident waste water that a small amount of leakage material or little fire bring, and can play lamination in the process that fire incident waste water leaves standstill in storage tank simultaneously, process of being more convenient for.
5, a large amount of waste water that fire incident produces directly pump into tank car through liquid collecting hole, transfer to the unit of qualification to carry out harmlessness disposing, store and outward transport process formative dynamics balance, finally reach the not outer row of Accident prevention waste water, object free from environmental pollution in collection.
