Embodiment
As shown in Figure 1, pig farm high-concentration sewage treatment system comprises combined air flotation, the biochemical treatment tank of biological filter and built-in spherical film, combined air flotation injects case continuously with two chemical reagent meterings respectively, materialized mud pond, biological filter is connected by pipeline with grille well, biological filter is connected by pipeline with one end of the biochemical treatment tank of built-in spherical film, the biochemical treatment tank of built-in spherical film is provided with oxygen supply equipment, the other end of the biochemical treatment tank of built-in spherical film is connected by pipeline with one end of settling tank, the other end of settling tank is connected by pipeline with materialized mud pond, materialized mud pond is connected by pipeline with one end of belt press filtration treatment facility, the other end of press filtration treatment facility is connected by pipeline with one end of anaerobic fixed film reactor, the other end of anaerobic fixed film reactor is connected by pipeline with one end of grille well.
Pig farm process for treating high-concentration sewage comprises one-level materialization and two steps of aerobic biochemical:
One-level materialization: the sewage through anaerobic hydrolysis and grille well filtration enters combined air flotation, with the speed of 260-300L/h, 350-400mL/h, in combined air flotation, inject the aluminium chlorohydroxide solution coagulating agent of 7.5%-10%, the emulsion PAM coagulant aids of 0.3-0.5% respectively, sewage is carried out to materialization processing, isolated organic pollutant is sent into materialized mud pond, by belt press filtration treatment facility, carry out solid-liquid separation again, separated dry dirt is made fertilizer, separated liquid enters anaerobic fixed film reactor, then enters combined air flotation repetition said process until isolate dry dirt;
Aerobic biochemical: the water completing by said process preliminary treatment enters biological filter and carries out anaerobic/anoxic processing filtering-depositing, then enter in the biochemical treatment tank of built-in spherical film, oxygen supply equipment carries out aerobic treatment to water body, spherical membrane technique is processed increases active sludge carrier volume, strengthen the capacity of resisting impact load of biochemical sludge, improve the adsorptive power of mud to the nitrogen phosphate and sulfur ion in water, last water enters settling tank and carries out mud-water separation, the sewage qualified discharge after processing or be directly used in pig farm and recycle.
PAM is poly-propionic acid amide, and emulsion PAM is cationic polymers.
Beneficial effect of the present invention: dry dirt is made fertilizer and can be promoted live pig to produce optimum ecological circulation development, drives the structure of agricultural production to optimize and revise; It is A that one-level materialization adds aerobic biochemical
2o+MBBR method is processed the sewage on pig farm, reduces expensive processing cost, is convenient to promote; Effectively process high density pig farm sewage, make it to reach discharging standards, in use, water reclaims, saving water resource; The application of emulsion PAM, when keeping sludge calorific value, improves the content of mud organic substance, has reached sludge reduction, innoxious object, for recycling sludge, has reserved the road of Sustainable development, has expanded the approach that biochemical sludge utilizes.
