Description

Sewage treatment device with automatic slag discharging function

Technical Field

The invention relates to the field of sewage treatment technology, in particular to a sewage treatment device with an automatic slag discharge function.

Background

Sewage is the effluent from life and production that is contaminated to some extent. The water which loses the original use function is called sewage for short.

Sewage may be defined as a waste-laden liquid or water mixed with ground water, surface water, snow storms, etc. discharged from residential, institutional, commercial or industrial areas from the point of view of the source of the sewage. Sewage is classified into many categories, and there are many techniques and processes for reducing the environmental impact of sewage accordingly. Sewage can be classified into these four categories according to the source of the sewage.

The first type: industrial wastewater is derived from sewage from manufacturing mining and industrial production activities, including runoff leachate from industrial or commercial storage, processing, and other wastewater that is not domestic sewage.

The second type: domestic sewage is sewage from a house, an office building, an office or the like; sanitary sewage; sewage water, including industrial waste water mixed in domestic sewage water in a sewer system. Garbage, various atmospheric particulates, and the like, which enter the water environment through surface runoff, soil erosion, farmland drainage, and the like. The method has the characteristics of dispersity, concealment, randomness, latency, accumulation, ambiguity and the like, so that the method is difficult to monitor and quantify, and the difficulty of research, prevention and control is high. The discharge of water pollutants into the body of water causes the substances of pollution.

In the third category: commercial sewage comes from commercial facilities and some components exceed the non-toxic, harmless sewage of domestic sewage. Such as restaurant sewage. Laundry sewage, animal feeding sewage, sewage generated by a hair salon, and the like.

The fourth type: surface runoff comes from rain, snow, highway sewage, water from urban and industrial areas, etc., and surface runoff does not seep into the soil and enters groundwater along streets and lands.

The common way of sewage treatment is to mix a medicament with sewage, adsorb and solidify pollutants in the sewage into solid sediments through chemical reaction, and then filter the sewage to realize the separation of the pollutants;

however, the existing online sewage treatment device has some problems, such as poor mixing reaction efficiency of sewage and medicament; and sewage and medicament constantly let in, solid-state precipitate also constantly produces, after a period of time, can pile up a large amount of solid-state precipitates on the filter screen, cause the filter screen filter effect to reduce, produce the pipe blockage even, and current scarfing cinder, row's sediment mode are mostly just shut down and clear up the filter screen, take out solid-state precipitate, but to online sewage treatment, this kind of mode can cause the interrupt of sewage treatment process, produce the problem.

Therefore, the inventor designs a sewage treatment device with an automatic slag discharge function, and solves the problems.

The following describes the use of the machine by taking this embodiment as an example:

the sewage inlet pipe 102 feeds sewage into the stirring tank 101, and the chemical inlet pipe 103 synchronously feeds a treatment chemical, such as a flocculating agent, into the stirring tank 101;

the servo motor 202 is started to drive the first bevel gear 203 to rotate, and based on the rotation of the bevel gears, on one hand, the first bevel gear 203 drives the third bevel gear 301 to drive the stirring shaft 302 to rotate, and the stirring shaft 302 drives the first-class stirring rod 303 to stir in the stirring tank 101, so that sewage and a medicament are mixed, a solid-state sediment is generated by an accelerated reaction, and the content of pollutants in the wastewater is reduced or reduced; the solid sediment flows into the filter cavity 105 along with the water flow through the guide pipe 104 and is filtered by the filter screen 107; the solid sediment is blocked by the filter screen 107 and is left on the filter screen 107, and the purified sewage is discharged through the drain pipe 106 and is introduced into the subsequent sewage treatment section;
