Fig. 3 is the sectional view along A-A face of reaction unit in Fig. 2.
embodiment
With reference to the accompanying drawings embodiments of the invention are described.The element described in an accompanying drawing of the present invention or a kind of embodiment and feature can combine with the element shown in one or more other accompanying drawing or embodiment and feature.It should be noted that for purposes of clarity, accompanying drawing and eliminate expression and the description of unrelated to the invention, parts known to persons of ordinary skill in the art and process in illustrating.
As Figure 1-3, waste disposal plant of the present invention comprises supply unit 7, and 8 and reaction unit 1.
Supply unit 7,8 for providing electric energy to reaction unit 1.Reaction unit 1 comprises the multiple battery lead plates 4 being placed in sewage lagoon.Wherein, the first limit of each battery lead plate 4 and the bottom of sewage lagoon are connected, and each battery lead plate is perpendicular to the liquid level for the treatment of sewage, and the polarity of every two adjacent electrode plates is contrary.
As a kind of embodiment, the Second Edge relative with the first limit of each battery lead plate is higher than the liquid level for the treatment of sewage.Each polarity is that the first side of positive battery lead plate and sewage lagoon is connected, and each polarity is that negative battery lead plate is connected with second side relative with the first side of sewage lagoon.
In addition, polarity is that positive battery lead plate does not contact with the second side of sewage lagoon, and polarity is negative battery lead plate does not contact with the first side of sewage lagoon.
So, after can ensureing that pending sewage enters sewage lagoon from entrance 3, along the direction of arrow flowing shown in Fig. 2,3.
When sewage disposal, after water enters sewage lagoon, alternately put because electrode is staggered, make water flow distance elongated, water retention time is elongated, has more times allow battery lead plate process organism and reduction, Adsorption of Heavy Metal Ions.Between battery lead plate, organism is decomposed at positive plate and forms foam and floats on the surface, and can clear up away easily; Heavy metal ion is reduced into simple substance at negative plate and is attached on negative plate, thus is separated with water body.So, the organism in sewage and heavy metal ion can be removed simultaneously.
In one embodiment, supply unit can comprise solar energy photovoltaic panel 7 and store battery 8.
Wherein, solar energy photovoltaic panel 7 is for converting solar energy into electrical energy.Electric energy for receiving and storage of electrical energy, and is provided to reaction unit 1 by store battery 8.
In one embodiment, solar energy photovoltaic panel 7 such as can be placed on the roof of fixed buildings, thus Appropriate application space, reduce the floor space of waste disposal plant.
By day, solar energy photovoltaic panel 7 starts to produce electric energy under the irradiation of sunlight, and a part of electric energy is used for making reaction unit work, and another part electric energy flows to store battery 8 and preserves, not have the situation reaction unit of illumination still can run to evening.So, the extraneous energy supply needed for this waste disposal plant can be made to reduce, and increase the working hour of waste disposal plant, improve sewage treating efficiency.
As a kind of preferred version, the reaction unit 1 of waste disposal plant can also comprise baffle group 5,6.
Baffle group is placed in the side of described sewage lagoon near water outlet 2, enters water outlet for avoiding the foam produced in sewage treatment process.
In one embodiment, baffle group 5,6 can comprise the first plate washer 5 and the second plate washer 6.
Wherein, the first plate washer 5 comprises baffle body and groove, is connected and perpendicular to the liquid level for the treatment of sewage, groove notch is upwards connected on plate washer body at the bottom of the pond of baffle body and sewage lagoon.
First side and second side of the second plate washer 6 and sewage lagoon are connected, and the body of the second plate washer 6 and the first plate washer 5 is in same perpendicular.The lower end of the second plate washer 6 is inserted in groove, and does not contact with the bottom land of groove.
In addition, the upper end of the first plate washer 5 is lower than the liquid level for the treatment of sewage, and the lower end of the second plate washer 6 is lower than the liquid level for the treatment of sewage.
By the first plate washer 5 and the second plate washer 6 of said structure and annexation, can ensure that the water after processing must behind the gap between the groove of the first plate washer 5 and the second plate washer 6 lower end, could discharge from the water outlet of sewage lagoon, so just can ensure that the foam produced in sewage treatment process can not be discharged through water outlet, enters follow-up processing links.
Waste disposal plant of the present invention also comprises bus cable 9, in order to the battery lead plate in the electrical energy transfer accumulators 8 that produced by solar energy photovoltaic panel 7 and treatment unit 1.
Bus cable comprises positive bus and negative bus.
