Description

technical field [0001] The invention relates to the field of tunnel engineering drainage, in particular to a working method of sewage treatment fluid control equipment. Background technique [0002] The tunnel construction project in the prior art is partly located in the water environment sensitive area of ​​the river basin, with a large line span, a wide range of strong karstification strata, and far-reaching interactive effects on the water environment. Surface engineering construction sewage may seep through the tunnel drainage holes, and groundwater iron and manganese may exceed the standard in some sections of the tunnel; in addition, due to the high requirements for water and soil conservation in areas such as engineering construction slag yards and construction sites. There are high requirements for engineering environmental protection and water and soil conservation, and there are also requirements for tunnel construction projects, so drainage becomes particularly i...

Problems solved by technology

[0004] 1. In the prior art, when the pharmacy is feeding the flocculation reaction tank, due to the large range of the flocculation reaction tank, it is difficult to evenly cover the entire reaction tank when feeding the drug, so it is difficult to achieve the effect of uniform reaction flocculation

[0005] . In the existing technology, when the pharmacy is used to feed the flocculation reaction tank, more than one kind of medicine is often applied. After the medicine is fully mixed, the flocculation effect is improved. However, in the prior art, two kinds of medicines are often poured into a reaction tank and then mixed. The degree of automation Poor and cumbersome flow control

[0006] 1. In the prior art, when the pharmacy feeds the flocculation reaction tank, ordinary ball valves are often used to control the flow rate. However, the opening control of the ball valve is not accurate and cannot be quantified. The reasons are as follows: the opening of the ball valve is not a linear change As the ball valve rotates, the change of the opening area is not a linear increase / decrease, but a curve or step change. Therefore, although the opening and flow can be controlled, it cannot be precisely controlled and quantitatively controlled.

[0007] 1. The one-way valve in 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 will easily cause the liquid that cannot flow out to remain, and in severe cases, it will cause a certain amount of water hammer, and if the liquid remains It is also a detriment to the precision control

[0008] , The confluence of the existing technology is often in the form of a zipper confluence, which causes a certain amount of water hammer and affects the life of the equipment

[0009] 1. The swirling disc of the prior art has a weaker converging effect and a relatively weaker mixing effect
