The specific implementation process is as follows:
referring to fig. 1, domestic garbage leachate (hereinafter referred to as sewage) is driven by a water pump 2 to sequentially pass through a water inlet 1 and a mechanical grid 3, when the sewage passes through the mechanical grid 3, impurities such as fibers, metals, stones and large particles in the sewage are filtered by the mechanical grid 3, and then the sewage automatically flows into a sewage deodorization regulating tank 4.
Besides uniformly mixing the sewage and precipitating medium-sized particulate matters in the sewage, the regulating tank also adds a deodorant to reduce the influence of foul gas generated by the sewage on the air of the surrounding environment. Sewage passing through the deodorization regulating tank 4 is pumped into a pretreatment device 11 by a delivery pump 6, polyaluminium chloride solution in a first storage tank 8 and polyacrylamide solution in a second storage tank 9 are fully mixed with sewage in a pipeline mixer 10 in the pretreatment device 7, the mixed sewage enters the bottom of a sedimentation tank of the pretreatment device 7 through a pipeline and passes through an inclined pipe from bottom to top, fine particles and part of organic pollutants in the sewage are coagulated into large particles and separated from water, and sludge is sent out by a sludge discharge pipe 14; then the sewage flow rises mechanically into the air flotation device 11, the light flocculate and the oil stain in the sewage are removed after the air flotation device 11 is started, and the separated oil stain and sludge are discharged through an oil discharge port 12 respectively. ,
the treatment of the wastewater itself is as follows: the sewage from which the particulate matter, oil stains and part of organic matters are removed enters the anaerobic biological tank 16 through a pipeline. Microorganisms released from the anaerobic microorganism slow-release balls in the anaerobic organism pool 16 are distributed in the whole anaerobic organism pool 16 through domestication, multiplication and release, when sewage enters the anaerobic organism pool 16, most of oil stains remained in the sewage are decomposed by oil removing bacteria in the anaerobic organism pool 16, most of other organic pollutants are decomposed by anaerobic COD removing bacteria, and ammonia nitrogen is decomposed by nitrogen removing bacteria.
The sewage treated by the anaerobic biological tank 16 enters an oxygen-enriched biological tank 18 through a conduit 15, at the moment, the residual oil stain and organic pollutants in the sewage are further decomposed by aerobic COD (chemical oxygen demand) removing bacteria, and ammonia nitrogen is converted into nitrate nitrogen by nitrogen removing bacteria; phosphorus is separated by phosphorus removing bacteria. Because the advanced MBR technology is adopted in the oxygen-enriched biological tank 18, the membrane bioreactor 19 in the prior art adopts a tubular ultrafiltration ceramic membrane, a suction pump 23 of the membrane bioreactor 19 and a reciprocating brush type self-cleaning technology, and because the prior pretreatment device 7 separates oil stains and sludge in sewage, the sewage entering the membrane bioreactor 19 cannot cause the surface of the ceramic membrane to be polluted, so that stable and efficient water purification is ensured, and the service life of the ceramic membrane is prolonged. Meanwhile, due to the application of the MBR technology, a secondary sedimentation tank is not required, and the occupied area is reduced.
Then the tubular ultrafiltration ceramic membrane in the membrane bioreactor 19 intercepts the sludge saturated with microorganisms in the aerobic biological tank, so that the concentration of the microorganisms in the oxygen-enriched biological tank 18 is several times higher than that in the conventional oxygen-enriched biological tank, and the treatment efficiency is enhanced.

The method is circulated continuously, and the ceramic membrane tube is ensured to maintain normal flux under normal pressure. The sewage which reaches the standard is discharged into a clear water tank 24 through a suction pump 23 of the membrane bioreactor to be used as backwashing water, redundant treated water overflows into an adsorption tank 25, and the water is deeply treated by the adsorption tank and then is discharged into the environmental water body through a water outlet 26.
The treatment method of the gas in the sewage is as follows: the gas separator 20 separates air into oxygen-enriched gas and others. The oxygen-enriched gas enters an aeration pipe 21 of the oxygen-enriched biological pond 18 and an aeration pipe 22 of the membrane bioreactor to provide sufficient oxygen for aerobic microorganisms. The rest of the air floaters 11 entering the pretreatment device 7 are used as carrier gas for separating water from sludge.
