Description

A sewage treatment fluid control equipment

technical field

The invention relates to the field of tunnel engineering drainage, in particular to a sewage treatment fluid control device.

Background technique

The tunnel construction project of the prior art is partly located in the water environment sensitive area of the watershed, with a large line span, a wide range of strongly karstified strata, and a far-reaching interactive impact on the water environment. Surface engineering construction sewage may seepage through the tunnel drainage holes, and some sections of the tunnel may have the influence of excessive iron and manganese in groundwater; in addition, due to the high requirements for soil and water conservation in areas such as engineering construction slag yards and construction sites. Engineering environmental protection, soil and water conservation requirements are high, and there are also requirements for tunnel construction projects, so drainage in tunnel construction becomes particularly important.

The deficiencies of the prior art tunnel drainage schemes are as follows:

1. When adding medicine to the flocculation reaction tank in the prior art, due to the large scope of the flocculation reaction tank, it is difficult to uniformly cover the entire reaction tank when the medicine is poured, so that it is difficult to achieve the effect of uniform reaction and flocculation.

2. In the prior art, when the pharmacy is used to pass the medicine to the flocculation reaction tank, more than one agent is often applied, and the flocculation effect is improved after the agent is fully mixed. Poor and cumbersome flow control.

. In the prior art, when the pharmacy is used to pass the medicine to the flocculation reaction tank, the ordinary ball valve is often used to control the flow rate. However, the opening degree control of the ball valve is not accurate and cannot be quantified. The reasons are as follows: the valve opening of the ball valve is not a linear transformation. As the ball valve rotates, the change of the opening area is not linearly increasing/decreasing, but a curve or step change, so although the opening and flow can be controlled, it cannot be precisely controlled and quantitatively controlled.

, The one-way valve of the prior art has a return spring, so that the one-way valve is closed when the pressure is not enough to open the one-way valve. However, this is easy to cause the residual liquid that cannot flow out, and in serious cases, it will cause a certain water hammer, and if the liquid remains It is also a detriment to precision control.

. The confluence of the prior art is often in the form of a zipper confluence, which causes a certain water hammer and affects the life of the equipment.

. The swirl disk of the prior art has a weak confluence effect and a relatively weak mixing effect.
