Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-4As shown, a vehicle-mounted sewage treatment system for construction sites has a main body of a treatment tank body 1, which is a hollow shell with a rectangular structure. An inlet pipe 2 is connected to the treatment tank body 1, and a water inlet bucket 3 is connected to one side of the inlet pipe 2. The inlet pipe 2 is used to collect the construction site sewage collected by the inlet bucket 3. The inlet bucket 3 is set to connect multiple sewer ditches and pipelines. Because the treatment tank body is a closed structure as a whole, the inlet bucket 3 is needed to expand the flow collection capacity of the inlet pipe 2.

[0021] A plurality of partitions 4 are arranged in the inner cavity of the processing tank body 1 , and the plurality of partitions 4 divide the inner cavity of the processing tank body 1 into a plurality of processing chambers which are connected in sequence.

[0022] An overflow port 5 is provided on the top of each partition 4 on the side away from the water inlet hopper 3, and a sedimentation auxiliary plate 6 is provided in each treatment chamber. The sedimentation auxiliary plate 6 extends downward from the top of the treatment tank body 1, and a filter screen 8 is connected to the bottom end of the sedimentation auxiliary plate 6. The other end of the filter screen 8 is horizontally connected to the partition 4.

[0023] A treatment agent feeding port 7 is provided on the treatment chamber adjacent to the water inlet pipe 2 , and an automatic treatment agent adding device is provided on the treatment agent feeding port 7 .

[0024] A water outlet is provided on the other side of the treatment tank body 1 corresponding to the water inlet pipe 2, and a water outlet pump 9 is connected to the water outlet through a water outlet pipe.

[0025] An observation port 10 is provided on the top of the processing tank body 1 , and an observation window is hingedly connected to the observation port 10 for observing the internal conditions of the processing tank body 1 .

[0026] The vehicle-mounted sewage treatment system for construction sites also includes a mobile chassis 11, the treatment tank body 1 is separately connected to the mobile chassis 11, the bottom surface of the treatment tank body 1 is provided with at least two pairs of connecting screws 12, the mobile chassis 11 is a traction wheel bracket, and the mobile chassis 11 and the two pairs of connecting screws 12 are fixedly connected by two pairs of nuts 13. The mobile chassis 11 and the treatment tank body 1 are connected by connecting bolts and nuts 13, and the treatment tank body 1 can be moved by the traction wheel chassis, which increases the flexibility and portability of the equipment layout.

[0027] Preferably, two pairs of lifting rings 14 are provided at the four corners of the treatment tank body 1 to facilitate lifting of the treatment tank body 1 .

[0028] The automatic treatment agent adding device comprises an adding pipe 15, which is a tube-shaped structure, and the bottom end of the adding pipe 15 is connected to the treatment agent feeding port 7, and the treatment agent feeding port 7 is provided with a feeding control valve 16, and the adding pipe 15 is provided with an adding control push rod 17. The treatment agent in the adding pipe 15 can be pushed out by controlling the push rod, and then the treatment agent can enter the treatment tank 1 in cooperation with the switch of the feeding control valve 16.

[0029] An electromagnetic flowmeter 18 is provided on the water inlet pipe 2, and the electromagnetic flowmeter 18 is electrically connected to the controller of the addition control push rod 17. The electromagnetic flowmeter 18 is used to detect flow data, thereby controlling the control push rod and the addition control valve 16, and controlling the addition speed and addition amount of the treatment agent.

[0030] The treatment tank 1 disclosed in the present application has three treatment methods, and the three treatment methods of sedimentation, filtration and flocculation are respectively set for the components in the construction site sewage; the automatic treatment agent addition device can be used to add flocculants, and a sedimentation auxiliary plate 6 is provided in the treatment chamber, and an overflow port 5 is provided at the top of the partition 4, so that after the sewage enters from the water inlet pipe 2, it will first go down through the sedimentation auxiliary plate 6 due to the existence of the sedimentation auxiliary plate 6 and then enter the next chamber from the overflow port 5. In this way, after the sewage enters, it will first settle due to the action of the sedimentation auxiliary plate 6, and the solid impurities in the sewage will be deposited to the bottom of the treatment tank 1 under the action of gravity, and the water will go up through the overflow port 5 to enter the next treatment chamber. In this process, since the bottom end of the sedimentation auxiliary plate 6 is connected to a filter screen 8, and the filter screen 8 is horizontally connected to the partition 4, the sewage also needs to pass through the filter screen 8, so the filter screen 8 can play a filtering role to intercept the solid impurities passing through.

[0031] In order to intercept heavy metal ions and other harmful impurities contained in sewage, treatment agents can be added to the sewage through an automatic treatment agent adding device. The treatment agents are mainly flocculants and softeners, so that the harmful ions therein can form flocculation and be intercepted by the filter 8.

[0032] In order to recycle the treated water, a water outlet is provided on the other side of the treatment tank 1 corresponding to the water inlet pipe 2. The water outlet is connected to a water outlet pump 9 through an outlet pipe. The treated water filtered and precipitated in multiple treatment chambers is sucked out by the water outlet pump 9 for recycling.
