德國的是外置泵,後期維護方便的多,美國用的是內置泵,如果出點問題修起來很麻煩。
② 污水提升器為什麼要選擇外置泵
對於一個家庭用戶來說,如何選擇適合自家使用的污水提升器是一個常遇到的難題。因為污水提升器進入中國的時間並不長,也因其屬於新型排污設備,了解的人少,只有一些專業技術從業人員及一些工程裝飾公司具備相關的專業知識。接下來給大家簡述一下,外置污水提升器的購買指南。
由於不同國家的污水排放法規不同,所以生產的污水提升器也有所不同,以德國為代表的污水提升器為外置式, 即水泵機頭裸露在外面,故稱為外置式;除德國外的其他國家如美國,義大利,法國,中國等污水提升器的水泵是放置在箱體內,故稱為內置式。
下面是購買外置污水提升器的幾個注意事項:
一、鑄鐵水泵優於不銹鋼水泵
外置污水提升器的水泵材質有不銹鋼與鑄鐵兩種,鑄鐵水泵的外殼一次成型,高溫不易變形,密封性與穩定性比不銹鋼水泵要好的多,製造成本高出不銹鋼水泵30%以上,這也就是為什麼很多污水處理廠用的水泵材質為多為鑄鐵原因;以下產品外觀看似相同,其實材質完全不同,價格也相差甚遠,建議別墅業主選擇耐用,穩定性高的鑄鐵泵。
二、水泵蝸殼選擇鑄鐵材質,不要選擇PE材質
水泵的渦殼是水泵排水過程中最易磨損的部分,含有雜質的污水在離心力的作用下高速經渦殼內排出,鑄鐵材質的蝸殼相比PE材質的蝸殼更加堅固耐磨,使用壽命更長,采購成本也要比PE蝸殼貴很多,而市場上銷售給客戶的多為PE材質的蝸殼,所以業主應注意甄別,避免花了高配的價格買的確是低配產品。
三、安裝配件要齊全
根據外置污水提升器的安裝規范及其資料顯示,每款設備底部都有手動排污泵的介面¢50mm,設備必須安裝手動排污泵,如在基坑內安裝,還需配置基坑排污泵,手動排污泵的作用是當水泵故障時須通過手動排污泵排空箱體內的污水,這樣才方便檢修水泵,如果沒有安裝手動排污泵的設備檢修時,必然會導致污水溢出,會造成嚴重的環境污染。
四、正確使用外置式污水提升器
外置式污水提升器由於產品設計的原因是無法連續啟動的,也就是常說的S3運行模式,原因是水泵外置,當電機過熱時無法做到快速冷卻,所以在用水量大或者需要連續運行的場所,建議選擇容積大的外置污水提升器。
五、避免價格陷阱
價格比較低的外置污水提升器基本是配置較低,或者配件不全的報價行為,建議業主認真核對其產品資料和報價單後再做出決定。
以上簡述供各位業主購買外置式污水提升器時作為參考

DSTE TYPE DOMESTIC SEWAGE TREATMENT EQUIPMENT
OPERATION INSTRUCTIONS
Operation instructions to the DSTE
I Use and scope
This set is mainly used to treat the domestic sewage or some kind of instrial waste water, such as the waste water from the restaurant , sanatorium, or school, etc.
II. Treatment Technology
This DSTE set is mainly adopt the method of the Biomembrane method to deal with the waste water, it is a quite mature method to remove the NH4-N content in the water nowadays, the parameter of the water quality is designed according to the waste quantity containing in the raw water:
Waste intake average parameter
BOD5≤250mg/l
CODcr≤400mg/l
NH3-N≤40mg/l
SS≤300mg/l
Grease≤40mg/l
Effluent average parameter
BOD5≤20mg/l
CODcr≤100mg/l
NH3-N≤15mg/l
SS≤70mg/l
Grease≤10mg/l
The main treatment technology flow is as follow:
Kitchen sewage Oil interceptor
Intake of the sewage Bar rack Retention pool Anaerobic tank
sludge recycle
Contact oxidation tank Sediment tank disinfection tank
To disposal sludge tank
The sediment tank is erect style tank, the up-flow velocity is 0.4---0.8mm/s, contact oxidation material is stereoscopic and elastic, the specific surface area of it is 300m2/m3, the O2 supply is designed according to the BOD5 and NH3-N content in the water, and the aeration period will be 6~8 hours.
The time for waste water stay in the anaerobic tank is 2-3 hours, after contact oxidation, the waste water and sludge backflow to the anaerobic, backwater ratio is (100--200%) according to the adjustment. The time the waste water be kept in the sediment tank should more than 1.5~2 hours, sludge in the sediment tank will be exalted to the sludge tank by air waiting for the contact oxidation, then the overflow will backflow to the retention basin retreated, the sludge in the tank would be cleaned periodically.
III Installation
1.Three forms of installation: ⑴underground installation; ⑵half underground installation;⑶on the ground installation. The basement must be flat, if the set is installed underground, the height between the basement and the surface of the ground should adopt the drawing, and make the excavation width exceed 500mm out of the foundation plate , which is better for pipe installation.
2. Everything about pipe installation and connection should be taken into consideration when the set is ready. Make sure the net weight is suit with the crane, and the installation sequence should adopt the designed drawing, tight the screws with the rubber washer so as to connect the pipes, make sure there isn』t any leaking in the conit joint.
3. The install direction and position should be correct, so do the interval between them.
4. Fix the set with the surface of the ground after the installation has been finished, make sure it is firmly fixed, and the set wouldn』t move in the future. Pour in water after finish installation to the full. Make sure there isn』t any leaking on the conit joint, and make sure the set wouldn』t in version or inclined because of rise of the water under the ground.
5. After correct installation, pour some soil into the interval and make it flat, make sure:
⑴ The cover of the manhole should higher than the surface for about 100mm;
⑵ The air intake pipe on the manhole wouldn』t be blocked by the soil.
6. Connect the electrical control wire with the set, pay attention to the running direction of the blower and the submersible sewage pump. The electrical control cabinet couldn』t be kept outdoor, because the sun or rain would destroy the control board.
7. Points of attention:
⑴ The place to install the set could not store up the water when it is raining, ⑵ The water outlet pipes should be 0.4m under the surface of the ground.
⑶ Make sure that there wouldn』t any heavy things on top of it, and no tracks would get through it.
⑷ There should always some waste water in the set to prevent the floatage of the set by the underground water.
IV Examine the set and start before use
Make sure the electrical wires, control panel wires and the voltage are all accord with requirement. The local control cabinet could not only be used to control submersible sewage pumps and the blowers at the same time, but also could monitor itself according to the working condition. It also have the ability to self protect and self alarm, beside that, manual switch and automatic exchange switch are also equipped. To examine the pipes of the pump before start to see whether it is seeping or bibulous or stifled.
The pump of this set is antiblock avusion type pump, the control of two pumps is through the liquid switch in the waste water basin, working pump start to work when the height raised to the start level; the spare pump start when the height raised to the highest level; pump stop working when the height fall to the low level. Check out whether the revolving direction of the blower is correct when it is started.
When the liquid level is lower than the pump starting height, both two pumps stop working. At this time, the blower start to work intermittently, working time should between 0~30 minutes, and the period of the intermittent start should between 0~2 hours.
The control of the sludge discharge in the sediment tank is air boost discharge by the electromagnetic valve, discharging cycle: 2hours/time, discharging time: 5~8minutes/time.
The control of the set should be finished according to the computer designed working procere one time, (only under some special conditions the hand –driven control could be used). If it is necessary, the manual control of the submersible sewage pumps and the blowers and the electromagnetic valve can be realized through turning the switch on or off by hand.
V. The cultivation of the biomembrane
1. The quantity of sewage which entering in the set should accord with the rated flux with no stop.
2. The oxygen volume from the blower should reced to half amount when starting the submersible sewage pump, blower, electromagnetic valve and the CLO2 generator。
3. Observe the material filled in the contact oxidation tank, the biomembrane has finished when a piece of yellow or black dope could be found on the surface. The process costs 7~15 days.
4. The best temperature should be: 15~25℃
5. If the density of the original sewage is to low, it would cost more time to cultivate the biomembrane, so when it is necessary, some kind of furtilizer should be added.
6. The pH value should be kept between 6 and 9, so that the original sewage could reach the step of contact oxidation.
7. When start, pour in small quantity of sewage into the sewage treatment system. After the bilmembrane is finished, Sewage could enter in the system in normal flux.
VI. The management of the operation
1. Turn the blower to the normal position.
2. Let the backflow ratio of the contact oxidation tank reach the best position.
3. Working as designed, often observe the cultivative situation of the biomembrane.
VII. Maintenance and fix the breakdown
1. Make sure that there wouldn』t any solid material content in the sewage, to prevent the block of the pipes.
2. Cover the manhole of the set so as to prevent the droping of some solid material.
3. The pH value should be kept between 6 and 9, in order to keep a better condition for cultivation.
4. Change the lubricating oil in the blower one time every six months.
5. Keep the entrance of the blower unblocked.
6. Fix the breakdown
