Abstract

A technique and apparatus for cleaning the cloudy water in river or lake is characterized by that the adsorption-filtering balls which are prepared from waste are used and the used balls can be used as raw material of building road. Its advantages are low cost and high speed.

Description

Muddy water becomes clear technology and device

Owing to the urban and rural economies fast development, the unprocessed rivers that just enter of large amount of sewage cause many water quality of river feculences, become muddy blackening in recent years, give a kind of dirt of people nauseating sensation, have had a strong impact on the appearance of the city image in city.Because its water surface area is bigger, very difficult with conventional method processing, expense is also higher.And municipal administration require these waters to become to beautify clearly just can, do not make tap water, so need not to disinfect.

Purpose of the present invention invents exactly that a kind of method is simple, the low muddy water that makes of expense becomes clear treatment technology, and sewage is clear, as clear as crystal by turbid rapid change, gives pleasant sensation, beautifies the environment.

Principle of the invention feature: [1] is based on absorption and filtration mechanism, use suction strainer ball colony and make medium, muddy water is carried out filtering, no disinfection becomes clear so only be applicable to the nontoxicity muddy water, can not make tap water after the processing, [2] suction strainer ball material is utilization of waste material, the treatment of wastes with processes of wastes against one another, [3] suction strainer ball can be used as (road surface) material of building the road after using.

Basic mechanical design feature of the present invention:＜1〉the muddy water processing costs; ≤ 0.3 yuan/ton,＜2〉processing cycles are short, processing speed: 30～300 tons/hour.＜3〉after the processing filtering, can make agricultural water.

Fig. 1 becomes clear total figure that handles for muddy water, and Fig. 2 is a globule body section in the suction strainer ball, and Fig. 3 is a suction strainer spheroid section, and Fig. 4 is the brick brick figure of suction strainer, and Fig. 5 forms for ground surface material.

It is as follows that muddy water becomes clear treating processes: see Fig. 1, muddy water (sewage) is earlier through pre-treatment: at first carry out precipitation process, to remove the bigger suspended substance of degranulation, 1 is the natural sedimentation pond, also can adopt coagulation sedimentation method (adding coagulating agent), 2 is fine and closely woven woven wire (stainless steel), 3 is fine particle sand (φ 2～4), its effect is to filter small granular suspended matters, 5 is the suction strainer fragment of brick, 4 are only described suction strainer ball colony, and it can adsorb and remove by filter microorganism and bacterium in microparticle suspended substance, the water, and the 6th, limpid bright clear water.

Described suction strainer ball 4, its material is a flyash, is the refuse behind the fire coal of fuel-burning power plant, pile up like a mountain, the modern treatment of wastes with processes of wastes against one another, and reduce cost of water treatment significantly.Flyash is coal dust incendiary product in high temperature gas flow, and its single body is the garden pearl, sees Fig. 2, and little garden pearl body has opening 7, and cavity is arranged in the body, and 8 is housing.The absorption filtration properties of flyash are better than gac.Add tackiness agent (cement and gypsum) in flyash, just can make the suction strainer spheroid, see Fig. 3,9 for connecting the tackiness agent of each garden pearl.

The prescription of suction strainer ball and brick is: flyash 70% ± 5, Portland cement 20～30%, terra alba 5～8% (by weight), moisture content is an amount of, make ball (φ 25～35) with balling equipment behind the mixing, after airing solidified, the ball that also will rub was handled: because of spherome surface has the excessive tackiness agent of one deck (cement and gypsum), it can block the opening of little garden pearl, just influences the suction strainer function of spheroid.Be contained in the ball ball operation that rubs of rolling in the machine that rubs.The size of suction strainer brick and the common brick that builds a house are similar, and hair also will rub in its two roomy sides.The suction strainer brick is built two-layer (see figure 1) by laying bricks or stones in woven wire one side, and the brickwork joint between two-layer will miss mutually, could improve whole suction strainer effect.Spheroid is through for some time (1～3 month), and the saturated gradually miopragia of its suction strainer amount just needs the suction strainer spheroid that more renews.The suction strainer spheroid through high-temperature disinfection treatment (high-temperature steam or burn with stove high temperature Sub-Notebooks), with its inner absorption and filter the dirt (or bacterium) that stays and burn, just can be used as road-making material after using, be mainly used in to pave, and sees Fig. 5.Spheroid mixes use with the stone 10 of paving the way, and requires as follows:

1, the volume of stone 10 is 5 times of spheroid,

2, portfolio ratio: spheroid 40%, stone 60%.

Spheroid itself has good physical strength, adds the processing requirement of stating, and spreads fine particle stone 11 and pitch 12 at top layer at last, just guarantees the weight capacity and the used suction strainer brick of intensity on road surface fully, cuts into fritter and also can make ground surface material.

Claims

1, muddy water of the present invention becomes clear technology and device, mainly comprises settling tank, casting bed, suction strainer spheroid etc.It is characterized in that:

Described suction strainer spheroid 4 its material formulas are: flyash 70%, cement 25%, terra alba 5% (by weight).

2, become clear technology and device according to right 1 described muddy water, it is characterized in that:

The exhausted spheroid, (road surface) material of after high-temperature sterilization, can building the road,

3, become clear technology and device according to claim 1,2 described muddy waters, it is characterized in that:

Described spheroid high-temperature disinfection treatment is with high-temperature steam or use the stove high-temperature roasting.
