Description

Sewage treatment formula drainage system for road

Technical Field

The invention relates to the technical field of road facilities, in particular to a sewage treatment type drainage system for roads.

Background

Road sewage discharge is an important part in urban sewage discharge and bears the discharge work of a large amount of domestic sewage, rainwater and road runoff sewage, so a drainage system mainly comprising a plurality of drainage pipelines is usually arranged on a road to realize the discharge work of road water flow.

However, in the prior art, the tail end treatment method is usually adopted for road sewage discharge treatment, namely, sewage is collected through a drainage pipeline and then discharged to a sewage plant for centralized treatment, so that the defect that when the drainage load of a drainage system is large, the treatment load of the sewage plant is increased, the treatment efficiency is lower than the water inlet efficiency, and a large amount of sewage is directly discharged without being treated is caused.

Disclosure of Invention

The invention aims to solve the problems that the treatment burden of a sewage plant is increased and the purification efficiency is influenced because the tail end treatment is generally adopted for road sewage discharge in the prior art, and provides a sewage treatment type drainage system for roads.

In order to achieve the purpose, the invention adopts the following technical scheme: a sewage treatment type drainage system for a road comprises a curb, wherein a filter screen is connected in the curb in a sealing manner, the top and the bottom of the filter screen are respectively and fixedly connected with a sliding block, a cavity is formed in the curb, a sliding chute with the size matched with that of the sliding block is formed in the cavity, one end, away from the sliding block, of the sliding chute is fixedly connected with a permanent magnet block, a groove is formed in the sliding chute in the top of the cavity in a penetrating manner, a balancing weight is connected in the groove in a sealing and sliding manner, the top of the balancing weight is fixedly connected with a spring, and the fixed end of the spring is;

one side of the cavity, which is far away from the filter screen, is fixedly connected with a plurality of impurity removing needles, the impurity removing needles are matched with meshes of the filter screen, a plurality of air inflators are arranged in the middle of the impurity removing needles, and one ends of air outlets of the air inflators are communicated with the cavity;

first liquid outlet and the second liquid outlet of size of a dimension difference are seted up to the bottom of curb and the other end of first liquid outlet and second liquid outlet communicates jointly and is equipped with the stock solution chamber of seting up in ground inside, the diameter of first liquid outlet is greater than the second liquid outlet, the second liquid outlet is close to one side of filter screen net and sealing connection has the connecting pipe, the other end intercommunication of connecting pipe is equipped with clean casing, the bottom of clean casing adopts the arc structure and its mass distribution is for getting on light and getting off heavy, clean casing top fixedly connected with branch, the clean ball of bottom fixedly connected with of branch, be equipped with the coagulant in the clean ball.

In above-mentioned sewage treatment formula drainage system for road, first drain pipe has been seted up in the side top intercommunication of clean casing, the lateral wall intercommunication in liquid storage chamber is equipped with the second drain pipe and the diameter of second drain pipe is greater than first drain pipe, sealing connection has the baffle in the first liquid outlet and the lateral wall of first liquid outlet seted up with baffle complex spacing groove, the sealed department between baffle and the spacing groove is equipped with the magnet structure of inter attraction, one side that the slider is close to the permanent magnet block is equipped with the magnetic layer that repulses with the permanent magnet block homopolar, first drain pipe and connecting pipe all adopt hose construction.

Compared with the prior art, the invention has the advantages that:

1. in the invention, intermediate treatment is realized in the drainage system by a way of treatment in the passage, thereby reducing the treatment pressure of a sewage plant to a certain extent, improving the sewage treatment efficiency, having the self-cleaning effect and avoiding the blockage of a drainage pipeline;

2. when the self-cleaning type water purifier is used, when the external drainage pressure is lower, the counterweight block in the curb cannot be subjected to upward water pressure, so that the filter screen is in an outer state at the moment, sewage enters the cavity in the curb through the physical filtering effect of the filter screen, the water pressure is lower at the moment, the first liquid outlet is closed, the sewage only enters the cleaning shell from the second liquid outlet, and the cleaning shell is set to be in a state that the lower part is heavier and the upper part is lighter in weight and has a larger radian at the bottom, so that the water is easy to swing left and right after entering the cleaning shell, and the self-cleaning type water purifier has the advantages that water is enabled to react with a coagulant in the cleaning ball, and floccules in the;

3. in the sewage discharging process, the cleaning shell is always in an unstable swinging state, so that sewage in the cleaning shell is effectively mixed and stirred, the sewage is fully coagulated and precipitated, the treated water overflows and is discharged after subsequent sewage enters, the sewage treatment effect in a channel is realized, and the problem of clogging of a screen connected with the first liquid outlet pipe in the overflowing process is effectively avoided along with the continuous swinging of the cleaning shell;

4. when the external drainage pressure is higher, the water inflow is larger than the water outflow of the first liquid outlet pipe, so that water can be gradually gathered in the curb cavity, when the water pressure is high enough, the balancing weight is pushed to move upwards, the sliding block has a space sliding towards the inner side of the curb, the filter screen moves towards the direction of the impurity removal needle, because the water pressure is high, and the needle point part of the impurity removal needle is smaller than the mesh diameter of the filter screen, so that after the impurity removal needle passes through partial meshes of the filter screen, large hair, filling and blocking particles attached to the filter screen are effectively removed, the cleaning effect on the filter screen is achieved, meanwhile, the filter screen extrudes the valve rod part of the inflator pump, so that the inflator pump outputs air bubbles to the inner side of the filter screen, and after the air bubbles collide with the filter screen to break, large impact force is generated, the cleaning effect on the filter screen is improved, and after the process, the water inlet speed of the filter screen is improved;

5. meanwhile, water pressure produces great pressure to the baffle of first liquid outlet, will make it break away from and the spacing groove between the effect that magnetism is inhaled mutually, then first liquid outlet is consequently opened, under this kind of state, water will be discharged through first drain pipe and second drain pipe respectively, when improving drainage effect, compromise treatment portion sewage, then avoided under the great state of blowdown pressure, the too high problem of water level takes place for the road, facilitates the use.
