The utility model is characterized in that the purification electrolytic apparatus is composed of a curvilinear form insulated electrolysis tube 3 and a direct current electrolysis power supply 4, and a sewage delivery pipe is connected to the entrance 31 of the electrolysis tube 3. A positive plate 32 and a negative plate 33 are separately installed on the electrolysis tube inner wall in relative parallel and connected with the positive and negative electrodes of the direct current electrolysis power supply 4 through a connection terminal 34 on the electrolysis tube 3 outer wall. The device can effectively remove metallic ions like chrome and carboxyl, hydroxyl and carbonyl ions contained in the sewage.
Description
A kind of sewage purifier relates in particular to a kind of tanning industry sewage physics treating plant.
Along with the fast development of tanning industry, the sewage pollution on the environment that produces in the process hides process is also more and more serious, has become one of important industrial pollution source.Have little and diffusing characteristics in China leather-making enterprises, the waste water of each processing enterprise often can not focus on, and the contaminated wastewater load that these enterprises produce in the process hides process is high.When using biochemical process treating plant and electrolytic process treating plant to handle leather-making industrial wastewater, often there are the following problems for small business: floor space is big, and about 40,000 m are taken up an area of in the sweeping field of handling 1600t sewage a day
2Investment is big, a day handles the treating plant of 1600t sewage and invests about more than 700 ten thousand yuan; Equipment working cost height, every cubic metre of tanning sewage processing costs is in 0.75-0.80 unit; Water after the processing can not recycle, water resource waste; To the strictness of processing environment temperature requirement, biological bacterium breeding temperature will remain on 35-40 ℃; Toxic substance in the waste water can not effectively be removed as sexavalent chrome, it can only be shifted; The equipment more complicated needs more staff to safeguard.
The purpose of this utility model provides a kind ofly can carry out electrolytic small-scale sewage treating plant, and it uses simple installation, floor space is few, simple in structure, cost is low, can effectively remove chromium ion.
The purpose of this utility model is to realize by following equipment: a kind of tanning sewage physical cleaning equipment, be made up of AC power, purifying electrolysis device, water delivery pipe fitting and support, its characteristics are that described purifying electrolysis device is made up of curved shape insulating electrolysis tube, dc electrolysis power supply; The sewage hydraulic pipe is communicated with the inlet of described electrolysis tube, and opposing parallel is separately installed with positive plate and negative plate on described electrolysis tube inwall, and is connected with the positive and negative electrode of dc electrolysis power supply by the connection terminal on the described electrolysis tube outer wall.
Above-mentioned treating plant, its characteristics are that described electrolysis tube is at least one deck U-shaped pipe, dual U-shaped pipe or S shape pipe.
Above-mentioned treating plant, its characteristics are that described dc electrolysis power source voltage is a safety voltage, and the distance between positive plate and the negative plate is not less than 140mm, and described electrolysis tube inner anode plate and negative plate length are generally 20-35m.
Above-mentioned treating plant, its characteristics are that described dc electrolysis power source voltage is 36V, electric current 100A, and the distance between positive plate and the negative plate is 160mm, and the length of positive plate and negative plate is about 26m.
For the leather-making industrial wastewater that contains materials such as chromate ion, carboxyl, hydroxyl, carbonyl radical ion and NaCl, chromium ion is attracted on the positive plate in electrolysis tube, form solid particulate, carboxyl, hydroxyl, carbonyl radical ion all produce floss near negative plate.The shaped form electrolysis tube prolonged electrolysis time and electrolyzer simple in structure, compact.Adopt the 1600t sewage floor space of handling purification system day of this equipment only to be 1% of conventional purification apparatus, because less investment, working cost are low, purifying waste water can be recycled, and has saved water resources.Owing to removed the metal ions such as chromium in the sewage, and formed chromium metal, turned waste into wealth.In addition, this treating plant is simple to operate, easy to maintenance, all can use under normal temps.Therefore, this equipment is specially adapted to small business and carries out sewage purification and handle.
Further specify embodiment of the present utility model below in conjunction with Figure of description
Fig. 1 is the synoptic diagram of a kind of double-U-shaped electrolysis tube of the present utility model
Fig. 2 is an A-A direction sectional view among Fig. 1
At treating plant shown in Fig. 1, Fig. 2, form by curved shape insulating electrolysis tube 3, dc electrolysis power supply 4, AC power, water delivery pipe fitting and support.The electrolysis tube inlet 31 of sewage by hydraulic pipe and electrolysis tube 3 is communicated with and enters electrolysis tube 3.On the inwall of electrolysis tube 3, vertically opposing parallel is separately installed with positive plate 32 and negative plate 33, and is connected with the positive and negative electrode of dc electrolysis power supply 4 by the connection terminal 34 that is fixed on electrolysis tube 3 outer walls.Dc electrolysis power supply 4 is to obtain by the AC power rectification, voltage or electric current by adjusting dc electrolysis power supply 4 and dwindle the distance between electrolysis tube 3 inner anode plates 32 and the negative plate 33 or its length that extends prolongs electrolysis time and makes metallic particles such as being adsorbed with chromium on the positive plate 32, the while is formed with floss near negative plate 33.For safety, the voltage of dc electrolysis power supply 4 adopts safety voltage, distance between positive plate 32 and the negative plate 33 generally is not less than 140mm, and sewage carries out electrolysis time by electrolysis tube 3 and is no less than 3min, and electrolysis tube 3 inner anode plates 32 are generally 20-35m with the length of negative plate 33.When the voltage of dc electrolysis power supply 4 was 36V, electric current was preferably about 100A, and the distance between positive plate 32 and the negative plate 33 is preferably about 160mm most, and positive plate 32 is generally 26m with negative plate 33 length.In Fig. 1, Fig. 2, the electrolysis tube 3 shown in the present embodiment is one deck dual U-shaped pipe.The electrolysis tube 3 of certain another kind of embodiment of the present utility model also can adopt U-shaped or S shape pipe, and in order to reduce floor space and to prolong electrolysis time and be convenient to maintenance, electrolysis tube 3 also can adopt bilayer or three-decker.
Adopt tanning sewage purification system of the present utility model, a day processing 1600t sewage floor space only is 1% of traditional method and an equipment, and investment also only is about the 2-3% of legacy equipment.1 cubic metre of sewage working cost of every processing is about about 0.30 yuan, purifies waste water to reach GB8978-88 national standard secondary emission level, can be recycled owing to purify waste water, and has also saved water resources.Owing to removed the toxic metal ions such as chromium in the sewage, also reclaimed rare metal chromium, thereby realized turning waste into wealth.In addition, this treating plant is simple to operate, maintenance, change very conveniently, and a staff can control fully, all can use under normal temps 0-45 ℃ situation simultaneously.Therefore, the utility model is specially adapted to small-sized small towns leather-making enterprises and carries out purification of waste water and handle.
