Description of drawings
Fig. 1 is a fundamental diagram of the present invention.
Embodiment
According to accompanying drawing the present invention is done further detailed description below:
Like rubbish and the sewerage integrated purification of Fig. 1 with produce fertile system, at first be that community's liquid dung dregs is formed and initial gross separation; With the food refuse in the kitchen, use the food refuse kibbler to be ground into pasty state (or microgranular), through sewer line, rush in community's closure septic tank with tap water.Water in the toilet, and stool and urine wait dirt, and through sewer line, water is flushed to community's ladder filtering type septic tank.After said two devices all is flushed to this community's ladder filtering type septic tank; Ladder filtering type septic tank divides two portions: liquid dung dregs settling tank and prefiltration sewage lagoon; The prefiltration sewage lagoon is lower than liquid dung dregs settling tank position, so sewage can lean on weight, through first filter screen from flowing out liquid dung dregs settling tank; First filter screen wherein is dismountable, and convenient the taking-up cleaned.Taking treatment tank away through transferpump then handles.The liquid dung dregs precipitates in settling tank gradually, continues to handle through the transhipment of liquid dung dregs transport pipe then.
Liquid dung conveying and solid-liquid separation, deodorizing, the liquid dung dregs is indoor to the solid-liquid separation of sealing through special pipe-line transportation, and through the robotization press filtration of belt filter press, last sewage flows in the foul water tank, is transported to next step through sewer line and handles; Water-containing sludge is transported away, and next step continues to handle.Whole process is carried out in the special workshop of sealing, and spray deodorant is innoxious mode of operation simultaneously.
WWT; Sewage in the treatment tank of sealing, through multistage WWT, passes through the uv lamp sterilization and disinfection through pipe-line transportation then, after the deodorizing, can become and reaches emission standard, the middle water that can supply afforestation to use.
The thermophilic fermentation compost; The mud that will contain suitable moisture adds an amount of powdery plant auxiliary material simultaneously (by agricultural wastes, like various straws, leaf; Branch, the plant auxiliary material that shell pericarp etc. is processed is used to increase nutrient, regulates moisture); A small amount of extra large breeze is through just mixing fermentation, turning; Processes such as aeration stop appropriate time, accomplish the high-temperature aerobic fermentation compost.Extra large breeze is wherein processed with the high-tech physical method by seabed mikrobe remains mineral, extremely microporous inorganic powder, and fundamental component is similar to shell, has the environment toxicological harmless, and the smelly power of suction suction is strong, the effect of slowly-releasing fertility.
